IMPORTANT SAFETY INFORMATION
12431-9-0408Page 4
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
by point with the members of your household. Someday when
there may not be a minute to lose, everyone's safety will depend
on knowing exactly what to do. If, after reading the following
information, you feel you still need more information, please
contact your gas supplier.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the odor
of LP-Gas prior to and while lighting pilot lights or perform-
ing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your LP-gas
dealer. A periodic sniff test of the LP-gas is a good safety
measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having
it refilled before it is completely empty.
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!

If this appliance is installed directly on carpeting, tile or other
combustible material other than wood flooring the appliance shall
be installed on a metal or wood panel extending the full width and
depth of the appliance.
The base referred to above does not mean the fire-proof base as
used on wood stoves. The protection is for rugs that are extremely
thick and light colored tile.
Installation in Residential Garages
Gas utilization equipment in residential garages shall be installed
so that all burners and burner ignition devices are located not less
than 18" above the floor.
Such equipment shall be located, or protected, so it is not subject
to physical damage by a moving vehicle.
Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equip-
ment or accessories and repair and servicing of equipment shall be
performed only by a qualified agency. The term "qualified agency"
means any individual, firm, corporation or company which either
in person or through a representative is engaged in and is respon-
sible for (a) the installation or replacement of gas piping or (b) the
connection, installation, repair or servicing of equipment, who is
experienced in such work, familiar with all precautions required
and has complied with all the requirements of the authority having
jurisdiction.
State of Massachusetts: The installation must be made by
a licensed plumber or gas fitter in the Commonwealth of
Massachusetts.
The installation must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code ANSI Z223.1/NFPA
54* Natural Gas and Propane Installation Code, CSA B149.1.
*Available from the American National Standards Institute, Inc., 11 West 42nd St.,
New York, N.Y. 10036.
High Altitudes
For altitudes/elevations above 2,000 feet, input ratings should
be reduced at the rate of 4 percent for each 1,000 feet above sea
level. Canadian High Altitudes for locations having an eleva-
tion above mean sea level between 2,000 feet (610m) and 4,500
feet (1370m), the manifold pressure is to be decreased from 4.0"
w.c. to 3.2" w.c. for Natural Gas and from 10.0" w.c. to 8.0" w.c.
for Propane Gas.
Piezo Pilot Ignitor Instructions
Depressing the red button completely causes a spark to occur at
the pilot. This is a substitute for a match which requires opening
the pilot hole cover.
To light the pilot, it is important that the electrode be 1/8" from
the thermocouple. The spark must occur at the point the burner
flame hits the thermocouple. The end of the electrode will be red
hot with the pilot on.
On a new installation with air in the gas line, it is suggested that a
match be used. The match will light the pilot faster than the piezo
under this condition.

Locating Gas Supply
The gas line can enter the unit either through the floor or outside
wall. The gas line opening should be made at this time. Location
of the opening will be determined by the position of floor joists
and the valve and union used for servicing.
Note: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a flexible
appliance connector cannot exceed three feet in length.
Figure 1
Consult the current National Fuel Gas Code, ANSI Z223.1 CAN/
CGA-B149 (.1 or .2) installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of
the unit. Where none exists, or where its size or location is not
adequate, contact your local authorized installer for installation
or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip line be installed near
the gas inlet. This should consist of a vertical length of pipe tee
connected into the gas line that is capped on the bottom in which
condensation and foreign particles may collect.
Figure 2
Method of Installing a Tee Fitting Sediment Trap
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2
psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the above procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve,
it will result in a hazardous condition.

Clearances
1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation.
2. The DV-55 minimum wall depth is 4 1/2 inches and maximum
wall depth is 13 inches. The use of tubes not supplied by the
manufacturer results in unsatisfactory performance.
3. The DV-55 can be attached to the wall or recessed into the wall
up to 4 inches in depth but the minimum 4 1/2 inches vent/air
intake system wall depth must be maintained. Example: If
furnace is recessed into the wall at a depth of 4 inches, the
minimum wall depth must be 8 1/2 inches.
4. The wall in which the furnace is recessed has (0) zero clearance
to the furnace sides and top.
5. When using side discharge registers, SOR-1 or SOK-1, the
furnace cannot be recessed into the wall.
6. Clearance to sidewall or combustible material is 4 inches.
7. Ceiling clearance is 4 inches.
8. Floor and rear wall clearance is (0) zero inches.
9. Clearance of 18 inches is required to sidewall or combustible
material when flush mounted SOR-1, side outlet register is
used. See Figure 4.
10. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 24 inches.
The vent terminal of a direct vent appliance with an input over
50,000 BTU per hour shall be located at least 12 inches from any
opening through which flue gases could enter a building. The bot-
tom of the vent terminal and the air intake shall be located at least
12 inches above grade.
WARNING: The nearest point of the vent cap should
be a minimum horizontal distant of six (6) feet from any
pressure regulator. In case of regulator malfunction, the
six (6) feet distance will reduce the chance of gas entering
the vent cap.
Figure 4
Figure 3
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure regu-
lator in the gas valve. Natural gas models will have a manifold
pressure of approximately 4.0" w.c. at the valve outlet with the
inlet pressure to the valve from a minimum of 6.0" w.c. for the
purpose of input adjustment to a maximum of 7.0" w.c. Propane
gas models will have a manifold pressure approximately 10.0"
w.c. at the valve outlet with the inlet pressure to the valve from a
minimum of 11.0" w.c. for the purpose of input adjustment to a
maximum of 13.0" w.c.
A 1/8" N.P.T. plugged tapping, accessible for test gauge connection,
is located on the outlet side of the gas control.
The built-in regulator comes on at approximately 1/4th pressure
and full on in 10 seconds.

Cutting Vent Tubes
This is the most important part of the installation. With the furnace
installed on wall the 6" diameter air inlet tube and the 4" diam-
eter flue outlet tube are to be marked and cut using the following
procedure.
1. Attach 6" diameter air inlet tube onto the collar of air drop
assembly. Be sure 6" diameter air inlet tube is placed as far as
possible onto the collar of the air drop assembly. Mark the 6"
diameter air inlet tube 1/2" beyond the outside wall. Remove
6" diameter air inlet tube from collar of air drop assembly.
2. Attach 4" diameter flue outlet tube onto flue outlet collar on
combustion chamber. Be sure 4" diameter flue outlet tube is
placed as far as possible onto the collar of flue outlet. Mark
the 4" diameter flue outlet tube 2 1/4" beyond the outside wall.
Remove 4" diameter flue outlet tube from collar of flue outlet
on combustion chamber.
3. Mark or wrap tape completely around the tubes at the marked
points to help in making a true cut. Do not crimp or enlarge
tubes.
Installing Vent Assembly
1. Place provided caulking beneath the edge of the outside
mounting plate. Use additional caulking to correct uneven
wall surface, such as clapboard.
2. Attach 6" diameter air inlet tube onto the collar of air drop
assembly. Attach caulked, outside mounting plate into the 6"
diameter air inlet tube. Position the outside mounting plate so
that 6" diameter air inlet tube has a slight downward slope to

When vent-air intake system is removed for servicing the furnace,
the following steps will assure proper reassembly and resealing of
the vent-air intake assembly.
1. Remove old caulking beneath the edge of the outside mount-
ing plate. Apply new caulking beneath the edge of the outside
mounting plate. Use additional caulking to correct uneven wall
surface, such as clapboard.
2. Remove old furnace cement from flue outlet collar on com-
bustion chamber and collar of vent cap. Remove old furnace
cement from both ends of 4" diameter flue outlet tube.
3. Attach 6" diameter air inlet tube onto the collar of air drop
assembly. Attach caulked, outside mounting plate into the 6"
diameter air inlet tube. Position the outside mounting plate so
that 6" diameter air inlet tube has a slight downward slope to
the outside. The downward slope is necessary to prevent the
entry of rainwater. Attach outside mounting plate to exterior
wall with (4) #10 x 1" screws provided.

4. Apply furnace cement to 4" diameter flue outlet collar on
combustion chamber and to 4" diameter collar on vent cap.
Attach 4" diameter flue outlet tube onto flue outlet collar on
combustion chamber. Attach vent cap into the 4" diameter flue
outlet tube. Attach vent cap to outside mounting plate with (3)
#10 x 1/2" screws provided.
5. Reassembly and resealing vent-air intake system is completed.
Installing a Vent Near a Window Ledge,
Other Type of Projection or on Siding (vinyl, aluminum, etc.)
Direct vent furnaces are designed to be installed on a uniform
outside wall. When the wind comes from any angle (up, down or
from either side), it must hit the vent cap equally over both the air
inlet and the flue outlet portions of the vent. Any wall projection,
such as a door or window casing, which disturbs the wind on one
side of the air inlet section will result in back pressure on the flue
section smothering the flame and eventual pilot outage.
When the vent cap is to be installed on siding or it appears that a
projection within 6" of any side of the air inlet section could shield
the air inlet section, the entire vent should be supported away from
the wall at least the distance of the projection. 2" x 4" framing
whose outside dimensions match the overall dimensions of the
mounting plate is recommended. The 2" x 4" framing protects sid-
ing from possible warpage or discoloration. All joints can then be
sealed and painted. The wall depth plus the additional depth of the
2" x 4" framing should not exceed a total depth of 13" for DV-55.
(See Figure 9)
Vinyl siding vent kit, DV-822, is available from Empire Comfort
Systems, Inc. The depth is 3", which enables the vent cap to be
extended away from siding or projections. The wall depth plus the
additional 3" depth of the vinyl siding vent cap extension should
not exceed a total depth of 13" for DV-55. (See Figure10)
Warning: When vinyl siding vent kit, DV-822 or 2" x 4"
framing is added to an existing installation (furnace is
installed) do not attempt to add sections of pipe to the flue
outlet tube or air inlet tube. An air tight seal is required for
both tubes. Refer to Parts List, page 16 to order tubes.

WARNING: If you do not follow these instructions exactly, a fire or explosion may result
causing property damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by
hand. When lighting the pilot, follow these instructions
exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch;
do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire
department.
C. Use only your hand to push in or turn the gas control
knob. Never use tools. If the knob will not push in or
turn by hand, don't try to repair it; call a qualified
service technician. Force or attempted repair may result
in a fire or explosion.
D. Do not use this appliance if any part has been under
water. Immediately call a qualified service technician
to inspect the appliance and to replace any part of the
control system and any gas control which has been under
water.
TO TURN OFF GAS TO APPLIANCE

The correct flame will be a short blue inner flame with a much
larger light blue outer flame. The main burner (Figure 12) shows
the approximate height of each part of the flame for each gas. The
burner does not have a primary air adjustment. The flame will be
correct if the factory-set pressure and orifice opening are used. After
the furnace has been operating, the burner ports may be blocked by
foreign matter carried in by combustion air. Therefore, cleaning of
the burner may be needed for proper flame.
To clean burner port disconnect the gas supply to the valve, and
remove the eight screws fastening the burner door. After remov-
ing the burner door from the combustion chamber, remove rear
burner, pilot burner and front burner. With front and rear burners
removed from furnace, force water into the ribbon ports and dry
with air pressure.
The correct pilot flame (Figure 11) will be blue, extending past
the thermocouple. The flame will surround the thermocouple just
below the tip.
Natural gas pilots require adjusting when the inlet gas pressure is
above 5" w.c. Remove the pilot cover screw on the control valve
(Figure 3, page 8), and turn the adjustment screw clockwise to
reduce flame. Replace pilot cover screw to eliminate gas leaking
at that control valve opening.
LP gas (propane) will not require adjustment.
After use, cleaning may be required for the proper flame.

Wiring
The appliance, when installed, must be electrically grounded in ac-
cordance with local codes or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70 or Canadian Electrical
Code, CSA C22.1, if an external electrical source is utilized. This
appliance is equipped with a three-prong [grounding] plug for
your protection against shock hazard and should be plugged
directly into a properly grounded three-prong receptacle. Do
not cut or remove the grounding prong from this plug. For an
ungrounded receptacle, an adapter, which has two prongs and a
wire for grounding, can be purchased, plugged into the ungrounded
receptacle and its wire connected to the receptacle mounting screw.
With this wire completing the ground, the appliance cord plug can
be plugged into the adapter and be electrically grounded. A 7/8" hole
is provided in the junction box for use with a conduit connector if
local codes require this type of protection.
Thermostat Installation
The thermostat should be installed in the same room as the furnace
4' to 5' above the floor and away from another heat source (cooking
stove, hot water heater, etc.) including walls and doorways with
a heat source in an adjoining room. Do Not Install Thermostat
on Outside Wall.
CAUTION: Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
WIRING
12431-9-0408 Page 15
Replacing Fan and Oiling the Motor
The fan motor should be cleaned and oiled once each heating season.
To reach the motor, withdraw the metal shroud surrounding the fan
blade by removing the screws on each side. Oil holes are located
on the top at each end of the motor. Use a few drops of #10 motor
oil. To clean the motor, blow air through its ventilation openings
with a vacuum cleaner or low pressure air source.
If fan motor is replaced, the silicone rubber gaskets, see Page 16,
Index No. 4, Part No. 712059, should also be replaced. The gaskets
must be stretched to fit the motor bolts into the gasket holes and then
the motor and gaskets installed on the motor mounting bars.
GENERAL : All furnaces have been fire-tested to check for proper
operation. This includes, main burner flame, pilot flame, fan opera-
tion, fan control, limit control and automatic valve operation. If
the furnace fails to function on initial installation, it is advisable
to re-check the following:
1. 115 volts to the junction box.
2. Inlet gas pressure.
3. The 24 volt system.
4. Type of gas being used and that shown on the rating label.
The Service Department at Empire Comfort Systems, Inc. may be
contacted to assist in servicing furnace or call a qualified service-
man..
Servicing the Pilot and Main Burners, Pilot Orifice, Thermo-
couple, and Main Burner Orifices: Disconnect the gas supply
at the inlet to the control valve. Then remove the burner door to
which the above components are attached.
Servicing The Fan Motor: The upper front panel, the shroud
surrounding the fan blade and fan blade must be removed. See
"Replacing Fan and Oiling the Motor" paragraph above.
Spark Igniter Does Not Light Pilot: With air in the gas line, such
as when the furnace is first installed or was off all summer, the
pilot flame may be too lean to ignite on the first few trials. Turn the
control valve knob to pilot position and depress the red reset button.
Holding the button down continually to bleed the line:
1. Use lighter rod to light pilot with a match.
2. Use the piezo ignitor at 30 second intervals until it lights.
If Electrode Does Not Produce Spark:
1. Check wire connections.
2. Check gap for pilot burner to the electrode tip. Should be
between 1/8" and 3/16". Electrode wire and tip must be more
than 1/4" away from all other metal components.
If Pilot Does Not Light By Any Means:
1. Check valve knob for being in the "Pilot" position.
2. Check pilot adjustment for being full open (counterclockwise
to open).
3. If gas is available in the supply tubing, the pilot orifice and/or
pilot burner is probably restricted by a spider web. Clean
pilot assembly and relight.
If Pilot Does Not Remain On After Releasing Knob:
1. Follow instructions and hold button down longer and
harder.
2. Determine if pilot flame extends past thermocouple; if not,
adjust input or clean pilot burner.
3. Replace thermocouple if millivolts read less than 15 mil-
livolts.
Pilot Outage During Normal Operation:
1. Check air inlet tube for a good tight fit at both ends (6"
diameter tube).
2. Check burner door and pilot hole cover for tight seal.
3. Check input by manifold pressure gauge or gas meter.
Main Gas Valve Does Not Open When Thermostat Is Turned
To On:
1. Check for 24 volts to valve by removing one wire and
touching to the SAME TERMINAL it was on. Terminal
should have a light spark. DO NOT SHORT ACROSS
TERMINALS, AS IT WILL BURN OUT THE WALL
THERMOSTAT.
2. Thermostat wires at the wall may be shorted, so check for
a faulty thermostat.
3. To check for line voltage to furnace, remove lower front
panel and switch compartment cover and short across two-
terminal fan control to allow fan to operate. (Figure 13)
