AIR FOR
WARNING
COMBUSTION
AND
VENTILATION
This heater shall not be installed in a confined space unless
provisions are provided for adequate combustion and ventilation
air. Read the following instructions to insure proper fresh air for
this and other fuel-burning appliances in your home.
Today's homes are built more energy efficient than ever. New materials, increased
insulation, and new construction methods help reduce heat loss in homes. 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 combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from
the house to operate. You must provide adequate fresh air for these appliances.
This will insure proper venting of vented fuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following is excerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Ventilation.
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 5 through 7 will help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows 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 defined as construction where:
a. walls and ceilings exposed to the outside atmosphere have a con-
tinuous water vapor retarder with a rating of one perm (6x10 "11per
pa.aec.m =) or less with openings gasketed or sealed and
b. weather stripping has been added on openable windows and doors and
c. caulking or sealants are applied to areas such as joints around window
and door frames, between sole plates and floors, between wall-ceiling
Joints, between wall panels, at penetrations for plumbing, electrical, and
gas lines, and at other openings.
If your home meets all of the three criteria above, you must provide addi-
tional fresh air. See Ventilation Air From Outdoors, page 7.
If your home does not meet all of the three criteria above, proceed to page 6.
10_604
Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ223.1, 1992 Section 5.3) defines a confinod
space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8
m 3 per kw) of the aggregate input rating of all appliances installed in that space and
an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000
Btu per hour (4.8 m 3per kw) of the aggregate input rating of all appliances installed
in that space. Rooms communicating directly with the space in which the appliances
are installed*, through openings not furnished with doors, are considered apart of the
unconfined space.
* Adjoining rooms are communicating only if there are doorless passageways or
ventilation grills between them. Continued _"

DETERMINING AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space-
Use this work sheet 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 an fuel burning appliances in the space.
Vent-free heater Btu/Hr
Gas water heater* Btu/Hr
Gas furnace Btu/Hr
Vented gas heater Btu/Hr
Gas fireplace logs Btu/Hr
Other gas appliances* + .Btu/Hr
Total = Btu/Hr
Example: Gas water heater 40,000 Btu/Hr
Vent-free heater + 39,000 Btu/Hr
Total = 79,000 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/Hr used)
Example: 51,200 Btu/T-Ir(maximum thespacecansupport)
79,000 Btu/Hr (actualamount of BtuiHr 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 wurksheet, adding the space of an adjoining room. If the extra space provides
an unconfined space, remove door to adjoining room or add ventilation grills between
rooms. See Ventilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.
C. Install a lower Btu/Hr heatar, if lowar Btu/Hr size makes room unconfined.
Iftbe actual Btu/Hr used is less than the maximum Btu/I-Irthe 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 be operated is smaller than
that defined as an unconfined space, provide adequate combus-
tion and ventilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3 or appli-
cable local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. When ventilating to an
adjoining unconfined space, you must provide two permanent openings: one within 12" of the
ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1
and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion
2nd Ventilation for required size of ventilation grills or ducts.
WARNING
Rework worksheet, adding the space of the adjoining unconfined
space. The combined spaces must have enough fresh air to supply all
appliances in both spaces.

and firebox must be cleaned of soot, creosote, ashes and loose paint
by a qualified chimney cleaner. Creosote will ignite if highly heated.
Inspect chimney flue for damage. If damaged, operate heater with
flue damper closed.
WARNING
Seal any fresh air vents or ash clean-out doors located on floor or wall
of fireplace. If not, drafting may cause pilot outage or sooting. Use a
heat-resistant sealant. Do not seal chimney flue damper.
WARNING
Never install the heater
• in a bedroom or bathroom unless installed as ave, nted appli-
• ance (Variable Manually-Controlled Models Only) (see page 13)
• in a recreational vehicle
• where curtains, furniture, clothing, or other flammable objects
are less than 36 inches from the front, top, or sides of the heater

INSTALLING DAMPER CLAMP ACCESSORY FOR
VENTED OPERATION
Note: When used as a vented heater, appliance must be installed only in a solid-
fuel burning fireplace with a working flue and constructed of non-combustible
material.
If your heater is a manually controlled model, you may use this heater as a vented
product. There are three reasons for operating your heater in the vented mode.
1. The fireplace does not meet the clearance to combustibles requirements for
vent-free operation.
2. State or local codes do not permit vent-free operation.
3. You prefer vented operation.
If reasons number 1or 2 above apply to you, you must permanently open chimney flue
damper. You must install the damper clamp accessory (to order, seeAccessories, page
33). This will insure vented operation (see Figure 10). The damper clamp will keep
damper open. Installation instructions are included with clamp accessory.
See chart below for minimum permanent flue opening you must provide. Attach
damper clamp so the minimum permaneni flue opening will be maintained at all times.

CONNECTING TO GAS SUPPLY
NOTICE
A qualified service person must connect heater to gas supply.
Follow all local codes.
CAUTION
Never connect heater directly to the propane supply. This heater
requires an external regulator (not supplied). Install the external
regulator between the heater and propane supply.
Installation Items Needed
Before installing heater, make sure you have the items listed below.
• external regulator (supplied by
installer, see page 16)
• piping (check local codes)
• sealant (resistant to propaneJLP gas)
• manual shutoff valve *
* An A.G.A. design-certified manual shutoffvalve with 1/8" NFFtap is an acceptabh
alternative to test gauge connection. Purchase the optional A.G.A. design-eertifiex
manual shutoff valve from your dealer. See Accessories, page 33.
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench

The installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and
14 inches of water. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator with the vent pointing down as
shown in Figure 13. Pointing the vent down protects it from freezing rain or sleet.

CAUTION
Use only new, black iron or steel pipe. Internally-tinned copper
tubing may be used in certain areas. Check your local codes. Use
pipe of 1/2" diameter or greater to allow proper gas volume to
heater. If pipe ts 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 14, page 17).
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.
CAUTION
Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown in Figure 14, page 17. Locate sedi-
ment trap where it is within reach for cleaning. Locate sediment trap where trapped
matter is not likely to freeze. A sediment 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.

The thermostat control knob can be set to any comfort level between Hi and Lo. The
thermostat will gradually modulate the heat output and flame height from higher to
lower settings, or pilot, in order to maintain the comfort level you select. The ideal
comfort setting will vary by household depending upon the amount of space to be
heated, the output of the central heating system, etc.
Note: Selecting the Hi setting with the control knob will cause the burner to remain
fully on, without modulating down in most cases.
