VENT-FREE NATURAL GAS RADIAN'I FLAME HEATER

AIR FOR

COMBUSTION AND

VENTILATION

WARNING: This heater shall

not be installed Inaconfined space

or unusually tight construction

unless provisions are provided

for adequate combustion and ven-

tilation air. Read the following in-

structions to insure proper fresh

air for this and other fuel-burning

appliances in your home.

Today's homes are built more energy effi-

cient than ever. New materials, increased

insulation, and new construction methods

help reduce heat loss inhomes. Home owners

weather strip and caulk around windows and

doors to keep the cold air out and the warm air

in. During heating months, home owners

want their homes as airtight as possible.

While it is good to make your home energy

efficient, your home needs to breathe. Fresh

air must enter your home. All fuel-burning

appliances need fresh air for proper com-

bustion and ventilation.

PROVIDING ADEQUATE

VENTILATION

The following are excerpts from National

Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-

tion 5.3, Air for Combustion and Ventila-

tion.

All spaces in homes fall into one of the three

following ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 6 through 8 will

help you classify your space and provide

adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and win-

dows may provide enough fresh air for

combustion and ventilation. However, in

buildings of unusually tight construction,

you must provide additional fresh air.

Unusually tight construction is de-

fined as construction where:

a°

Exhaust fans, fireplaces, clothes dryers, and

fuel burning appliances draw air from the

house to operate. You must provide ad-

equate fresh air for these appliances. This b.

will insure proper venting of vented fuel-

burning appliances.

walls and ceilings exposed to the

outside atmosphere have a con-

tinuous water vapor retarder with

a rating of one perm (6x10 "11kg

per pa-sec-m =)or less with open-

ings gasketed or sealed and

weather stripping has been

added on openable windows and

doors and

caulking or sealants are applied

to areas such as joints around

window and door frames, be-

tween sole plates and floors, be-

tween wall-ceiling joints, be-

tween wall panels, at penetra-

tions for plumbing, electrical, and

gas lines, and at other openings.

If your home meets all of the three

criteria above, you must provide ad-

ditional fresh air° See Ventilation Air

From Outdoors, page 8.

If your home does not meet all of the

three criteria above, proceed to Deter-

mining Fresh-Air Flow for Heater

Location, page 7.

Confined and Unconfined Space

The National Fuel Gas Code (ANS Z223. l,

1992 Section 5.3) defines a confined space

as a space whose volume is less than 50

cubic feet per 1,000 Btu per hour (4.8 m3per

kw) of the aggregate input rating of all

appliances installed in that space and an

unconfining space as a space whose volume

is not less than 50 cubic feet per 1,000 Btu

per hour (4.8 m3per kw) of the aggregate

input rating of all appliances installed in that

space. Rooms communicating directly with

the space in which the appliances are in-

stalled*, through openings not furnished

with doors, are considered a part of the

unconfined space.

This heater shall not be installed in a con-

fined space or unusually tight construction

unless provisions are provided for adequate

combustion and ventilation air.

* Adjoining rooms are communicating only

if there are doorless passageways or ventila-

tion grills between them.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between

the rooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height = cu. ft. (volume of space)

Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of

the space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

(volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. =51.2 or 51,200 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free heater Btu/Hr

Gas water heater* Btu/Hr

Gas furnace Btu/FIr Example: Gas water heater 30,000 Btu/Hr

Vented gas heater Btu/Hr Vent-free heater + 28,000 Btu/Hr

Gas fireplace logs Btu/Hr Total = 58,000 Btu/Hr

Other gas appliances* + Btu/Hr

Total =Btu/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

Btu/Hr (maximum the space can support)

Btu/Hr (actual amount of Btu/l-lr used)

Example: 51,200 Btu/Hr (maximum the space can support)

58,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.

You must provide additional fresh air. Your options are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-

ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 8.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.

C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/I-lr the space can support, the space is an unconfined space. You will need no

additional fresh air ventilation.

WARNING: If the area In which the heater may beoperated Is smaller than that defined as an unconfined space

or If the building is of unusually tight construction, provide adequate combustion and ventilation air by one of

the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3, or applicable local codes.

C. MOUNTING HEATER WITH

OPTIONAL HEARTH BASE

TO OPTIONAL MANTEL See

instructions included with

mantel kit.

Assembling Mantel

IMPORTANT: Only use the optional man-

tels specified in this manual. See Accesso-

ries, pages 24 and 25 for proper mantel kits.

This heater is only approved for use with

models GMF800(A,B )/GMU801 (A,B),

GMg00F(A,B)/GM901U(A,B), GM700F/

GM701U, GMC22F/GMC23U/GMC24U,

GMC32F(B)/GMC33U(B), and GMC26F/

GMC27U/GMC28F mantel kits. Using any

other mantel will void the A.G.A. approval

for this heater. Do not use models

GMF800(A,B)/GMU80 1(A,B),

GM900F(A,B)/GM901U(A,B), and

GM70OF/GM701U, GMC22F/GMC23U/

GMC24U, GMC32F(B)/GMC33U(B), and

GMC26F/GMC27U/GMC28F mantels with

any other product. Before installing mantel

to heater, the heater must be mounted on the

optional hearth base.

Installing Mantel to Heater

_k WARNING: If installing the

GHB802 or GHB802A base on

heater, and using with a GA se-

ries heater blower accessory

along with a GS601 surround or a

GM800 or GM900 series mantel,

the surround or mantel clearance

to back wall should be 3/4 inch.

This will improve flame appear-

ance and combustion.

Use only a GHB802B, GHB802C,

OR GHB38 series hearth base if

using a GA series heater blower

accessory with a GM70O series,

GMC32F series, or GMC33U se-

ries mantel.

CONNECTING TO GAS

SUPPLY

NOTICE: A qualified service per-

son must connect heater to gas

supply. Follow all local codes.

WARNING: Never connect

heater to private (non-utility) gas

wells. This gas is commonly

known as wellhead gas.

IMPORTANT: Check gas line pressure be-

fore connecting heater to gas line. Gas line

pressure must be no greater than 14 inches

of water. If gas line pressure is higher,

heater regulator damage could occur.

CAUTION : Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

your local codes. Use pipe of 1/2"

or greater diameter to allow

proper gas volume to heater. If

pipe is too small, undue loss of

pressure will occur.

Installation must include a manual shutoff

valve, union, and plugged 1/8" NPT tap.

Locate NPT tap within reach for test gauge

hook up. NPT tap must be upstream from

heater (see Figure 20).

Apply pipe joint sealant lightly to male

threads. This will prevent excess sealant

from going into pipe. Excess sealant in pipe

could result in clogged heater valves.

_k CAUTION: Use pipe ioint seal-

ant that is resistant to liquid pe-

troleum (LP) gas.

Install sediment trap in supply line as shown

in Figure 20. Locate sediment trap where it

is within reach for cleaning. Locate sedi-

ment trap where trapped matter is not likely

to freeze. Asediment trap traps moisture

and contaminants. This keeps them from

going into heater controls. If sediment trap

is not installed or is installed wrong, heater

may not run properly.

_k CAUTION: Avoid damage to

control. Hold gas fitting with

wrench when connecting it to gas

piping and/or fittings.

ITHERMOSTAT I

CONTROL OPERATION

The thermostatic control used on this

heater differs from standard thermostats.

Standard thermostats simply turn on and

off the burner. The thermostat used on

this heater senses the room temperature.

The thermostat adjusts the amount of gas

flow to the burner. This increases or de-

creases the burner flame height. At times

the room may exceed the set tempera-

ture. If so, the burner will shut off. The

burner will cycle back on when room

temperature drops below the set tem-

perature. The control knob can be set to

any heat level between HI and LO.

Note:. The thermostat sensing bulb mea-

sures the temperature of air near the

heater cabinet. This may not always agree

with room temperature (depending on

housing construction, installation loca-

tion, room size, open air temperatures,

etc.). Frequent use of your heater will let

you determine your own comfort levels.

MANUAL LIGHTING 1

PROCEDURE

1. Remove front panel (see Figure 2,

page 4).

2. Follow steps 1 through 5 under Light-

ing Instructions, page 15.

3. With control knob pressed in, strike

match. Hold match to pilot until pi-

lot lights.

4. Keep control knob pressed in for 30

seconds after lighting pilot. After 30

seconds, release control knob.

5. Replace front panel.

6. Turn control knob counterclockwise

to desired heating level. The

main burner should light. Set control

knob to any heat level between HI

and LO.

INSPECTING

BURNER

Check pilot flame pattern and burner flame

pattern often.

PILOT FLAME PATTERN

Figure 25 shows acorrect pilot flame pat-

tern. Figure 26 shows an incorrect pilot

flame pattern. The incorrect pilot flame is

not touching the thermocouple. This will

cause the thermocouple to cool. When the

thermocouple cools, the heater will shut

down.

If pilot flame pattern is incorrect, as shown

in Figure 26
