WARNING

Important
Environmental Concerns!
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment. Trane advocates the responsible handling of
all refrigerants-including industry replacements for CFCs
such as HCFCs and HFCs.

Responsible Refrigerant Practices!
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified. The Federal Clean Air Act
(Section 608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that

© 2012 Trane All rights reserved

must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.

WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.

General Information
Description
The duct furnace design is certified by ETL for use with
natural and LP (propane) gases. ANSI and NFPA Standards
as well as Canadian installation codes referred to in this
manual are the ones that were applicable at the time that
the design was certified. In addition, the duct furnace may
be installed on the downstream side of a cooling unit,
without need of a bypass duct.
If the unit is to be installed at an altitude exceeding
2,000 feet (610 m) above sea level, derate the input by
4 percent for each 1,000 foot (305 m) rise above sea level.
Special orifices are required for installations above
2,000 feet (610 m).
When units are installed in Canada, any reference to
derations at altitudes in excess of 2000 feet (610 m) are to
be ignored. At altitudes of 2000 to 4500 feet (610 to
1372 m), the units must be orificed to 90 percent of the
normal altitude rating, and be so marked in accordance
with the ETL certification.

“Installation Codes for Propane Gas Burning
Appliances and Equipment”. These indoor duct
furnaces have been designed and certified to
comply with CSA 2.6. Also see sections on
installation in “Aircraft Hangers,” p. 11 and
“Public Garages,” p. 11.
•

Do not alter the duct furnace in any way or
damage to the unit and/or severe personal injury
or death could occur!

•

Turn off the gas supply and disconnect all
electric power, including remote disconnects
before servicing unit. Follow proper lockout/
tagout procedures to ensure the power can not
be inadvertently energized and the gas can not
be inadvertently turned on. Failure to turn off
gas or disconnect power before servicing could
result in death or serious injury.

•

Follow installation instructions CAREFULLY to
avoid creating unsafe conditions. All wiring
should be done and checked by a qualified
electrician, using copper wire only. All external
wiring must conform to applicable local codes
and to the latest edition of the National
Electrical Code ANSI/NFPA No. 70.

•

All gas connections should be made and leaktested by a suitably qualified individual, per
instructions in this manual. Also follow
procedures listed in “Gas Equipment Start-Up,”
p. 32.

•

Use only the fuel for which the duct furnace is
designed (see rating plate). Using LP gas in a
heater that requires natural gas, or vice versa,
will create the risk of gas leaks, carbon
monoxide poisoning and explosion.

General Safety Information
Important:

This product must be installed by a licensed
plumber or gas fitter when installed within
the Commonwealth of Massachusetts.

WARNING
Safety Alert!
You MUST follow all recommendations below. Failure
to do so could result in death or serious injury.
•

Installation must be made in accordance with
local codes, or in absence of local codes with the
latest edition of ANSI Standard Z223.1 (N.F.P.A.
No. 54) National Fuel Gas Code.
All of the ANSI and NFPA Standards referred to
in these installation instructions are those that
were applicable at the time the design of this
appliance was certified. The ANSI Standards are
available from the CSA Information Services,
1-800-463-6727. The NFPA Standards are
available from the National Fire Protection
Association, Batterymarch Park, Quincy, MA
02269. These duct furnaces are designed for use
in airplane hangars when installed in
accordance with current ANSI/NFPA No. 409
and in public garages when installed in
accordance with current NFPA No. 88A and
NFPA No. 88B.
If installed in Canada, the installation must
conform with local building codes, or in absence
of local building codes, with CSA-B149.1
“Installation Codes for Natural Gas Burning
Appliances and Equipment” or CSA-B149.2

GLND-SVX01B-EN

Important:

Do not attempt to convert the furnace
for use with a fuel other than the one
intended. Such conversion is
dangerous, as it could create the risks
listed previously.

•

Make certain that the power source conforms to
the electrical requirements of the furnace.

•

All field-installed wiring must be completed by
qualified personnel. All field-installed wiring
must comply with NEC and applicable local
codes. Failure to follow this instruction could
result in death or serious injuries.

•

Special attention must be given to any
grounding information pertaining to this duct
furnace. To prevent the risk of electrocution, the
furnace must be securely and adequately
grounded. This should be accomplished by
connecting a grounded conductor between the
service panel and the furnace. To ensure a proper

7

General Information
ground, the grounding means must be tested by
a qualified electrician.

Duct furnace components

•

Do not insert fingers or foreign objects into the
furnace or its air moving device. Do not block or
tamper with the heater in any manner while in
operation or just after it has been turned off, as
some parts may be hot enough to cause injury.

•

This furnace is intended for general heating
applications ONLY. It must NOT be used in
potentially dangerous locations such as
flammable, explosive, chemical-laden or wet
atmospheres.

•

When connecting to existing gas lines be sure to
valve off the gas supply ahead of connection
point. To avoid explosion or possible fire, always
purge all residual gas from piping before cutting
into existing line or removing threaded fittings.
Failure to remove all gas vapors could result in
death or serious injury or equipment or propertyonly-damage.

NOTICE:
Equipment Damage!

NOTICE:
Maintain Minimum Thermostat Setting!

Do not install duct furnaces in corrosive or flammable
atmospheres! Premature failure of, or severe damage to
the unit could result! Avoid locations where extreme
drafts can affect burner operation. Duct furnaces must
not be installed in locations where air for combustion
would contain chlorinated, halogenated or acidic
vapors. If located in such an environment, premature
failure of the unit could occur!

Duct furnaces should not be installed to maintain low
temperatures and/or freeze protection of buildings. A
minimum of 50°F (10°C) thermostat setting must be
maintained. If duct furnaces are operated to maintain
lower than 50°F (10°C), hot flue gases are cooled inside
the heat exchanger to a point where water vapor (a flue
gas by-product) condenses onto the heat exchanger
walls. The result is a mildly corrosive acid that
prematurely corrodes the aluminized heat exchanger
and can actually drip water down from the duct furnace
onto the floor surface. Additional duct furnaces should
be installed if a minimum 50°F (10°C) thermostat
setting cannot be maintained. Failure to follow these
recommendations could result in equipment or
property damage.

When the unit is equipped with an automatic gas ignition
system, the duct furnaces must be installed such that the
gas ignition control system is not directly exposed to water
spray, rain, or dripping water.
Note: Location of duct furnaces is related directly to the
selection of sizes. Basic rules are as follows:

Aircraft Hangers. Duct furnaces must be installed in
aircraft hangars and public garages as follows: in aircraft
hangars, duct furnaces must be at least 10 feet (3.0 m)
above the upper surface of wings or engine enclosures of
the highest aircraft to be stored in the hangar, and 8 feet
(2.4 m) above the floor in shops, offices and other sections
of the hangar where aircraft are not stored or housed.
Refer to current ANSI/NFPA No. 409, Aircraft Hangars. In
Canada, installation is suitable in aircraft hangars when
acceptable to the enforcing authorities.
Public Garages. In repair garages, duct furnaces must
be installed in a detached building or room separate from
repair areas as specified in the latest edition of NFPA 88B,
Repair Garages.
In parking structures, duct furnaces must be installed so
that the burner flames are located a minimum of 18 inches
(457 mm) above the floor or protected by a partition not
less than 18 inches (457 mm) high. Refer to the latest
edition of NFPA 88A, Parking Structures.
In Canada, installation must be in accordance with the
latest edition of CSA B149 “Installation Codes for Gas
Burning Appliances and Equipment.”

GLND-SVX01B-EN

WARNING
Overheating or Flooding Could Cause Fire
or Explosion!
Overheating or flooding (where any part of the duct
furnace has been under water) could result in fire or
explosion. Should overheating occur, or the gas supply
fails to shut off, shut off the manual gas valve to the
duct furnace before shutting off the electrical supply.
Do not use the duct furnace if any part has been under
water. Immediately call a qualified service technician to
inspect the duct furnace and replace any gas control
which has been underwater. Failure to follow these
recommendations could result in death or serious
injury.

WARNING
Hazardous Gases and Flammable Vapors!
Exposure to hazardous gases from fuel substances
have been shown to cause cancer, birth defects or other
reproductive harm. Improper installation, adjustment,
alteration, service or use of this product could cause
flammable mixtures. To avoid hazardous gases and
flammable vapors follow proper installation and set up
of this product and all warnings as provided in this
manual. Failure to follow all instructions could result in
death or serious injury.

Clearances

Ductwork

WARNING
Combustible Materials!
Maintain proper clearance between the unit heat
exchanger, vent surfaces, and combustible materials.
Refer to unit nameplate and installation instructions for
proper clearances. Improper clearances could result in a
fire hazard. Failure to maintain proper clearances could
result in death or serious injury or property damage.
Maintain adequate clearances around air openings into
combustion chamber:
Table 3.

Minimum clearances

Sides

6” (152 mm)

Top

6” (152 mm)

Bottom

6” (152 mm)

Flue

6” (152 mm)

Properly designed and installed ductwork, providing a
uniformly distributed flow of air across the surfaces of the
heat exchanger, is essential to satisfactory unit
performance and life of the equipment.
All duct connection flanges/seams must be sealed to
prevent air leaks. Sealant/tape must be suitable for
temperatures 250°F (121°C) minimum.

NOTICE:
Use 90° Duct Connection Flanges!
Ducts must be properly connected to duct furnaces for
operation. Do not straighten the 90° duct connection
flanges on the duct furnaces. Straightening the 90° duct
connection flanges will affect the operation of the
furnace and will void the warranty.
If uniform air distribution is not obtained, install additional
baffles and/or turning vanes in the ductwork.

Note: When the clearances required for accessibility are greater than the
minimum required safety clearances, the accessibility clearances
take precedence.

Figure 7 and Figure 8 illustrate recommended ductwork
designs for both the straight-through and elbowed air inlet
arrangements.

Accessibility

Figure 7.

If the unit is a bottom service access type, allow a
minimum of 21 inches (533 mm) at the bottom of the unit
to facilitate servicing the burners and pilot, or six inches
(152 mm) if the unit has a side access burner drawer.
Provision should also be made to assure accessibility for
recurrent maintenance purposes.

Recommended design for field installation of
ductwork for straight-through arrangement

Drafts
Avoid installing the duct furnace in an extremely drafty
location. Strong drafts may cause pilot outage. Units with
intermittent pilot ignition may be preferable in areas
where drafts cannot be avoided.
Atmospheres containing commercial solvents or
chlorinated hydrocarbons will produce corrosive acids
when coming in contact with the flames. This will greatly
reduce the life of the gas duct furnace and may void the
warranty. Avoid such areas.

WARNING
Fire Hazard!
If the gas duct furnace is to be used in a building
classified as having a hazardous atmosphere, the
installation must comply with the standards set by the
National Board of Fire Underwriters. Consult the
authorities having jurisdiction before starting the job.
Failure to follow recommendations could result in
death or serious injury.
The duct furnace must be installed on the positive
pressure side of the air circulation blower.

resulting in a low air temperature rise, install a damper
bypass around the gas duct furnace to bypass a portion of
the air.

Suspension
WARNING
Heavy Objects!
Ensure that all hardware used in the suspension of each
duct furnace is capable of supporting the unit weight.
Failure to do so could result in unit falling off its
mounting location, which could result in death or
serious injury.

NOTICE:
Equipment Damage!
Access panels large enough to observe smoke and
reflected light, and to detect the presence of leaks in the
heating equipment, are required both upstream and
downstream from gas duct furnaces. These panels must
be sealed to prevent air leaks. If allowed by local
regulations, install canvas connectors between the
ductwork and fan discharge opening to eliminate the
transmission of mechanical vibration.

Air Flow
The installation is to be adjusted to obtain an air
throughput within the range specified on the appliance
rating plate.

Combustion Inlet Air Ventilation
Inlet Air From Another Room
If the duct furnace is installed in a tightly constructed room
or compartment, provide two inlet air openings. The size
of each vent opening should be no less than one square
inch (6.452 square centimeters) of free area for each 1000
Btu/hr. (293 W) input. Each opening must not be less than
100 square inches (645 square centimeters).

The duct furnace must be hung level from side to side
and front to back, from four suspension points provided
at the top of the unit. Failure to do so could result in
poor performance and/or premature failure of the unit.
Refer to Figure 9, p. 14 for typical suspension
arrangements.

WARNING
Heavy Objects!
Make certain that the lifting methods used to lift the
duct furnace and the method of suspension used in the
field installation of the duct furnace are capable of
uniformly supporting the weight of the furnace at all
times. Make certain that the structure to which the
furnace is mounted is capable of supporting its weight.
Under no circumstances must the heater gas lines, the
venting system or the electrical conduit be used for
support. Failure to follow recommendations could
result in death, serious injury, or property damage.

Inlet Air From Outdoors
If the enclosed space is to have inlet combustion air from
the outside, the vent opening must not be smaller than one
square inch (6.452 square centimeters) of free area for
each 2500–3000 Btu/hr (733–879 W) input. Each opening
must not be less than 100 square inches (645 square
centimeters).

Bypass
When a gas duct furnace is installed to operate in
conjunction with a summer air conditioning system, the
cfm air delivery of the system blower should be adjusted
to meet the design air volume requirements for cooling. If
this cfm delivery is greater than that required for heating,

company to make certain that the existing line is of
adequate size to handle the combined load.

WARNING
Flammable Vapors!
When connecting to existing gas lines be sure to valve
off the gas supply ahead of connection point. To avoid
explosion or possible fire, always purge all residual gas
from piping before cutting into existing line or
removing threaded fittings. Failure to remove all gas
vapors could result in death or serious injury or
equipment or property-only damage.

Pipe Sizing
To provide adequate gas pressure at the gas duct furnace,
size the gas piping as follows:
1. Find the ft3/hr by using the following formula:
ft3/hr =

Input
Btu per ft3

2. Refer to Table 4, p. 17. Match “Length of Pipe” with
appropriate “Gas Input - Ft3/Hr” value. This value can
then be matched to the pipe size at the left of the table.
Example: It is determined that a 67 foot (20.4 m) run of
gas pipe is required to connect a 200 MBtu gas duct
furnace to a 1,000 Btu/ft3 (0.29 kW) natural gas supply.
200,000 Btu/hr
1,000 Btu/ft3

= 200 ft3/hr

Using Table 4, p. 17, a 1-inch nominal diameter pipe is
needed.
Notes:
•

See “General Safety Information,” p. 7 for English/SI
(metric) unit conversion factors.

•

If more than one gas duct furnace is to be served by the
same piping arrangement, the total cubic feet per hour
input and length of pipe must be considered.

•

If the gas duct furnace is to be fired with LP gas, refer
to Table 4 and consult the local LP gas dealer for pipe
size information.

WARNING
Hazard of Explosion and Fire!
Heater installation for use with propane (LP gas) must
be made by a qualified LP Gas Dealer or LP Gas Installer
to ensure that all appropriate codes, installation
procedures, and precautions have been followed.
Failure to follow these instructions could result in death
or serious injury.
Before any connection is made to an existing line
supplying other gas appliances, contact the local gas

Notes:
1. Determine the required ft3/h by dividing the rated heater input by 1000. For SI / Metric measurements: Convert unit Btu/h to kilowatts. Multiply the
unit input (kW) by 0.0965 to determine m3/h.
2. FOR NATURAL GAS: Select the pipe size directly from the table.
3. FOR PROPANE GAS: Multiply the ft3/h (m3/h) value by 0.633; then use the table.
4. Refer to the metric conversion factors listed in “General Safety Information,” p. 7 for more SI unit measurements/conversions.
(a) Maximum capacity of pipe in cubic feet of gas per hour (cubic meters per hour) for gas pressures of 0.5 psig (3.5 kPa) or less, and a pressure drop of
0.5 inch water column (124.4 Pa) (based on a 0.60 specific gravity gas).

Pipe Installation
1. Install the gas piping in accordance with applicable
local codes.
2. Check gas supply pressure. Each duct furnace must be
connected to a manifold pressure and a gas supply
capable of supplying its full rated capacity as specified
in Table 5, p. 18. A field LP tank regulator must be used
to limit the supply pressure to maximum of 14 in. wc
(3.5 kPa). All piping should be sized in accordance with
the latest edition of ANSI Standard Z223.1 National
Fuel Gas Code; in Canada, according to CSA B149. See
Table 1, p. 9, and Table 4, p. 17 for correct gas supply
piping size.
If gas pressure is excessive on natural gas applications,
install a pressure regulating valve in the line upstream
from the main shutoff valve.

WARNING
Hazard of Explosion!
Adequately support the piping to prevent strain on the
gas manifold and controls. To prevent explosion, fire, or
gas leaks, support piping so that piping does not sag or

Your venting system must not be blocked by any snow,
snow drifts, or any foreign matter. Inspect your venting
system to ensure adequate ventilation exists at all
times! A blocked venting system could result in carbon
monoxide poisoning. Symptoms of such condition
include grogginess, lethargy, inappropriate tiredness, or
flu-like symptoms. Failure to follow these
recommendations could result in death or serious
injury.

Venting for Power Vented (Category III)
Duct Furnaces
All duct furnaces must be vented!

WARNING
Carbon Monoxide!
Your venting system must not be blocked by any snow,
snow drifts, or any foreign matter. Inspect your venting
system to ensure adequate ventilation exists at all
times! A blocked venting system could result in carbon
monoxide poisoning. Symptoms of such condition
include grogginess, lethargy, inappropriate tiredness,
or flu-like symptoms. Failure to follow these
recommendations could result in death or serious
injury.

WARNING
Risk of Fire and Carbon Monoxide
Poisoning with Improper Piping!
Never use a pipe of a diameter other than that specified
in Table 1, p. 9! To prevent pipe from melting and
introducing exhaust fumes into the air supply, never
use PVC, ABS or any other non-metallic pipe for
venting! To prevent fan restriction, an elbow should
never be attached directly to the venter. Failure to
follow recommendations could result in death or
serious injury or equipment damage.
All venting installations shall be in accordance with the
latest edition of Part 7, venting of Equipment of the
National Fuel Gas Code, ANSI Z223.1, or applicable
provisions of local building codes for power vented units.
Also see p. 21 for additional Canadian installations.
Horizontal vent systems must be in compliance with UL
1738 for installations in the United States, and ULS636 for
installations in Canada.
Power vented units are designed to be used with single
wall vent pipe utilizing horizontal or vertical venting
arrangements. These arrangements must terminate
external to the building using either a single wall or
double wall vent. See Figure 11, p. 20 through Figure 19,

GLND-SVX01B-EN

p. 24 for special installation requirements regarding these
venting conditions.

WARNING
Risk of Carbon Monoxide Poisoning with
Type B Vent!
Do not use a type B double wall vent internally within
the building on power vented units! Type B vent does
not seal well under positive pressure and could result in
exhaust fume leaks. Failure to follow these
recommendations could result in death or serious
injury.
If double wall venting (other than Type B; see preceding
warning) is used, components which are UL Listed and
approved for Category III positive pressure venting
systems MUST be used.
A Briedart Type L, Field Starkap or an equivalent vent cap
must be supplied by the customer for each power vented
unit. The vent pipe diameter MUST be as specified in
Table 1, p. 9 (“D” Dia. Flue Opening). A reducer must be
field installed for 100 through 175 MBh Unit Sizes. All 300
through 400 MBh Unit sizes are factory equipped with the
required flue increaser. Refer to Figure 11, p. 20 through
Figure 19, p. 24 for additional requirements.
The venting system for these appliances shall terminate at
least four feet (1.2 m) below, four feet (1.2 m) horizontal
from, or one foot (0.3 m) above any door, window, or
gravity air inlet into any building.
Through the wall vents for these appliances shall NOT
terminate over public walkways, or over an area where
condensate or vapor could create a nuisance or hazard or
could be detrimental to the operation of regulators, relief
valves, or other equipment.
The vent pipe equivalent length must be five feet (1.5 m)
minimum and must not exceed 50 feet (15.2 m).
Equivalent length is the total length of straight sections
PLUS 15 feet (4.6 m) for each 90 degree elbow, eight feet
(2.4 m) for each 45 degree elbow, and 10 feet (3.0 m) for
the vent cap.
Maintain six inches (152 mm) between vent pipe and
combustible materials. A minimum of 12 inches (305 mm)
of straight pipe is required from the venter outlet before
installing an elbow in the vent system. Never attach an
elbow directly to the venter (see preceding warning).
Use single wall pipe constructed of 26 gauge galvanized
steel or material of equivalent durability and corrosion
resistance for the vent system. For installation in Canada,
use pipe constructed from 0.025-inch thick aluminum or
0.018-inch thick stainless steel.
Any run of single wall vent pipe passing through an
unheated space must be insulated with an insulation
suitable to 550°F.

19

Installation: Piping
The vent terminal must be installed with a minimum
clearance of four feet (1.2 m) from electric meters, gas
meters, regulators and relief equipment.
Seal ALL vent pipe joints and seams to prevent leakage.

silicone sealant or 3M #425 aluminum foil tape or
equivalent.

Reconnect all wires according to the unit’s wiring
diagram.
Figure 11.

(Optional) Top vent position

The vent system must be installed to prevent collection of
condensate. Vertical vent pipes should be equipped with
condensate drains. Pitch horizontal pipes downward 1/4
inch per foot (21 mm per m) toward outlet for condensate
drainage.
Horizontal portions of the venting system shall be
supported at maximum intervals of four feet (1.2 m) to
prevent sagging (in Canada, support at three feet (1 m)
minimum intervals).
Insulate single wall vent pipe exposed to cold air or
running through unheated areas.

WARNING
Carbon Monoxide!
Never operate duct furnaces without combustion air
and flue gas piping in place. Each unit MUST have its
own combustion air system and MUST NOT be
connected to other vent systems or to a chimney. Your
venting system must not be blocked by any snow, snow
drifts, or any foreign matter. Inspect your venting
system to ensure adequate ventilation exists at all
times! Failure to follow these recommendations could
result in death or serious injury.

Start-Up
Operation
Power Vented Duct Furnaces with
Intermittent (Spark) Pilot Ignition
WARNING
Check and Test Safety Devices!
It is the installer’s responsibility to check all safety
controls! Check and test the operational functions of all
safety devices supplied with this unit, and ensure that
all are operating effectively. Failure to do so could result
in unsafe conditions and could result in death, serious
injury or property damage.

Explanation of Controls
1. The duct furnace is equipped with a dual automatic gas
valve and electric ignition device (separate from the
gas valve on most models) which provide the following
functions:
a. The duct furnace is equipped with a power vent
system consisting of a power venter motor and
blower, pressure switch, and sealed flue collector in
place of the conventional draft diverter.

NOTICE:
Operate Unit within Specified Units!
Never operate the unit beyond the specified limits,
severe damage to, and/or premature failure of the unit
will result!
b. The power venter motor is energized by the room
thermostat on a call for heat. The pressure switch
measures the flow through the vent system and
energizes the indirect spark ignition system when
the flow is correct.

WARNING
Risk of Fire and Carbon Monoxide
Poisoning!
The pressure switch MUST NOT be bypassed. The unit
MUST NOT be fired unless the power venter is
operating. Failure to follow these recommendations
could result in death or serious injury.

NOTICE:
Additional Devices!
The addition of external draft hoods or power venters is
not permitted. Addition of such devices could cause
severe unit malfunction or failure!

c. The indirect spark ignition system consists of an
ignition control module, a dual combination gas
valve, and a spark-ignited pilot burner. When the
pressure switch closes, the pilot valve opens and a
spark is generated to light the pilot burner. When
the flame sensing circuit senses that pilot flame is
established, the main gas valve is opened to supply
gas to the main burners. When the thermostat is
satisfied, the vent system is de-energized and both
valves are closed to stop all flow of gas to the unit.
d. Pilot solenoid valve also functions as a main gas
valve to provide redundancy.
e. Pressure regulator provides proper and steady gas
pressure to the main burners.
f. Manual shutoff valve for service and long term
shut-down. (Separate from the automatic valve on
some models.)
2. The high limit switch interrupts the flow of electric
current to the main gas valve in case the heater
becomes overheated.
3. The fan switch delays the operation of the fan until the
heater is warmed, then keeps the fan running after the
gas has been turned off until the useful heat has been
removed. The start-up fan delay must not exceed
90 seconds from a cold start.
4. The wall thermostat (supplied optionally) is a
temperature sensitive switch which operates the vent
system and ignition system; it turns the main gas valve
ON or OFF to control the temperature of the space
being heated. It must be mounted on a vibration free,
vertical surface away from air currents, in accordance
with the instructions furnished with the thermostat
(also refer to “Installation: Electrical,” p. 25).

Start-Up
1. Open the manual valve supplying gas to the unit
heater, and with the union connection loose, purge air
from the gas line. Tighten the union and check for gas
leaks, using a soapy water solution only.

WARNING
Hazard of Explosion!
Never use an open flame to detect gas leaks. Explosive
conditions may occur. Use a leak test solution or other
approved methods for leak testing. Before attempting
to light or relight the pilot, wait 5 minutes to allow gas
which may have accumulated in the burner
compartment to escape. Failure to follow
recommended safe leak test procedures or pilot
lighting/relighting instructions could result in death or
serious injury or equipment or property-only-damage.
2. Open the manual valve on the unit heater.
3. Turn ON electrical power.

GLND-SVX01B-EN

27

Start-Up
4. The unit should be under the control of the thermostat.
Turn the thermostat to the highest point and determine
that the power venter motor starts and the pilot and
main burners ignite. Turn the thermostat to the lowest
point and determine that the power venter motor shuts
off and pilot and main burners are extinguished.
5. If pilot adjustment is required, remove the pilot
adjustment seal cap and adjust the pilot screw to
obtain proper flame. Clockwise rotation decreases
pilot flame size. Replace the cap.
6. Turn the thermostat to the desired position.
7.

Refer to “Gas Pressure Adjustments,” p. 30 for more
specifications.

Shut-Down
1. Turn the valve selector knob to the “OFF” position.
2. Turn off the electricity.
3. To relight, follow the instructions in “Start-Up,” p. 27

Gas Pressure Adjustments
Adjust the gas pressure as follows:
1. NATURAL GAS: Best results are obtained when the
heater is operating at its full input rating with the
manifold pressure of 3.5 inches wc (0.9 kPa).
Adjustment of the pressure regulator is not normally
necessary since it is preset at the factory.
However, field adjustment may be made as follows:
a. Attach manometer at pressure tap plug adjacent to
control outlet.
b. Remove the regulator adjustment screw cap,
located on the combination gas valve.
c. With a small screwdriver, rotate the adjustment
screw counterclockwise to decrease or clockwise to
increase pressure. Do not force beyond stop limits.
d. Replace regulator adjustment screw cap.
2. PROPANE GAS: An exact manifold pressure of
10.0 inches wc (2.5 kPa) must be maintained for proper
operation of the heater. If the unit is equipped with a

accordance with the ETL certification.
(a) This schedule is for units operating at normal altitudes of 2000 feet
(610 m) or less. SPECIAL ORIFICES ARE REQUIRED FOR INSTALLATIONS ABOVE 2,000 FEET (610 m).

Primary Air Shutter Adjustment
After the unit has been operating for at least 15 minutes,
adjust the primary air flow to the burners. Turn the frictionlocked, manually-rotated air shutters clockwise to close, or
counterclockwise to open.
For correct air adjustment, close the air shutter until yellow
tips in the flame appear. Then open the air shutter to the
point just beyond the position where yellow tipping
disappears. Refer to Figure 22.
Note: There may be momentary and spasmodic orange
flashes in the flame. This is caused by the burning
of airborne dust particles, and should not be
confused with the yellow tipping, which is a stable
or permanent situation when there is insufficient
primary air.

Pilot Adjustment
1. Remove the pilot adjustment cap.
2. Adjust the pilot screw to provide a properly sized
flame.
3. A proper pilot flame is a soft steady flame that
envelops 3/8- to 1/2-inch (9.5 to 12.7 mm) of the flame
sensor tip.
4. Replace the pilot adjustment cap.

Manifold Pressure Adjustment
If the manifold pressure requires minor adjustment,
remove the cap from the pressure regulator and turn the
adjustment screw clockwise to increase the pressure, or
counterclockwise to decrease the pressure. The adjusted
manifold pressure should not vary more than 10 percent
from the pressures specified in Table 8, p. 30.

Maintenance
WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures
recommended in this section of the manual could
result in exposure to electrical, mechanical or other
potential safety hazards. Always refer to the safety
warnings provided throughout this manual concerning
these procedures. When possible, disconnect all
electrical power including remote disconnect and
discharge all energy storing devices such as capacitors
before servicing. Follow proper lockout/tagout
procedures to ensure the power can not be
inadvertently energized. When necessary to work with
live electrical components, have a qualified licensed
electrician or other individual who has been trained in
handling live electrical components perform these
tasks. Failure to follow all of the recommended safety
warnings provided, could result in death or serious
injury.

Periodic Service
All Maintenance/Service information should be recorded
accordingly on the inspection sheet provided in this
manual (see “Gas Equipment Start-Up,” p. 32).
Note: The heater and vent system should be checked
once a year by a qualified technician.

WARNING
Hazardous Voltage and Gas!
Turn off the gas supply and disconnect all electric
power, including remote disconnects before servicing
unit. Follow proper lockout/tagout procedures to
ensure the power can not be inadvertently energized
and the gas can not be inadvertently turned on. Failure
to turn off gas or disconnect power before servicing
could result in death or serious injury.
Important:

Gas tightness of the safety shut-off valves
must be checked on at least an annual basis.

WARNING
Hazard of Explosion!
Never use an open flame to detect gas leaks. Explosive
conditions may occur. Use a leak test solution or other
approved methods for leak testing. Failure to follow
recommended safe leak test procedures could result in
death or serious injury or equipment or property-onlydamage.
To check gas tightness of the safety shut-off valves, turn off
the manual valve upstream of the appliance combination
control. Remove the 1/8-inch pipe plug on the inlet side of
the combination control and connect a manometer to that
tapping. Turn the manual valve on to apply pressure to the
combination control. Note the pressure reading on the
GLND-SVX01B-EN

manometer, then turn the valve off. A loss of pressure
indicates a leak. If a leak is detected, use a soap solution to
check all threaded connections. If no leak is found,
combination control is faulty and must be replaced before
putting appliance back in service.
Should maintenance be required, perform the following
inspection and service routine:
1. Inspect the area near the unit to be sure that there is no
combustible material located within the minimum
clearance requirements listed in this manual (see
“Installation: Mechanical,” p. 11 and Table 3, p. 12).

WARNING
Combustible Materials!
Maintain proper clearance between the unit heat
exchanger, vent surfaces and combustible materials.
Refer to unit nameplate and installation instructions for
proper clearances. Improper clearances could result in a
fire hazard. Failure to maintain proper clearances could
result in death or serious injury or property damage.
2. Turn off the manual gas valve and electrical power to
the gas duct furnace.
3. To clean or replace the main burners, remove the
bottom panel and compress the spring by moving the
burner toward the manifold. Slide the opposite end of
the burner downward from the locating slot while
retaining spring is still compressed. Pull the burners
away from the manifold.
4. With the burners removed, wire brush the inside
surfaces of the heat exchanger.
5. Remove any dirt, dust, or other foreign matter from the
burners using a wire brush and/or compressed air.
Ensure that all parts are unobstructed. Inspect and
clean pilot burner if necessary.
6. Reassemble the gas duct furnace by replacing all parts
in reverse order.
7.

Complete the appropriate unit start-up procedure as
given in “Operation,” p. 27 (see lighting instruction
plate on the access side of the unit).

8. Check the burner adjustment (see “Primary Air Shutter
Adjustment,” p. 30).
9. Check all gas control valves and pipe connections for
leaks.
10. Check the operation of the automatic gas valve by
lowering the setting of the thermostat, stopping the
operation of the gas duct furnace. The gas valve should
close tightly, completely extinguishing the flame on
the main burners.
11. Check the operation of the pilot safety device by
closing the pilot line valve, extinguishing the pilot
flame. Within one minute the automatic gas valve

33

Maintenance
should close, extinguishing the flame on the main
burners.
12. Inspect and service the blower section of the system.
13. Check and test the operational functions of all safety
devices supplied with your unit.
