operate, or service this heater. Improper use of this heater can cause serious injury ordeath from burns, fire, explosion, electrical shock, and carbon monoxide
poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, ornausea. If
you have these signs, the heater may not be
working properly. Get fresh air at once! Have heater serviced. Some people are more affected by carbon monoxide than others.
These include pregnant women, people with heart or lung disease or anemia, those under the influence of alcohol, and those at high
altitudes. Propane/LP Gas: Propane/LP gas is odor-
less. An odor-making agent is added to the gas. The odor helps you detect a gas leak.
However, the odor added to the gas can fade. Gas may be present even though no odor
exists. Make certain you read and understand all
Warnings. Keep this manual for reference. It is your guide to safe and proper operation
of this heater.

AIR FOR COMBUSTION AND VENTILATION
_[_ WARNING: This heater shall
not be installed in a confined space unless provisions are pro-
vided for adequate combustion and ventilation air. Read the fol-
lowing instructions 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 in homes. Home own- ers 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 pos-
sible.
While it is good to make your home energy efficient, your home needs tobreathe.Fresh air must enter your home. All fuel-burning
appliances need fresh air for proper com- bustion and ventilation.
Exhaust fans, fu:eplaces, clothes dryers, and fuel burning appliances draw air from the
house to operate. You must provide ad- equate fresh air for these appliances. This
will insure proper venting of vented fuel- burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Venti- lation.
All spaces inhomes fall into one of the three following ventilation classifications: 1.Un-
usually Tight Contruction; 2. Unconfined Space; 3. Confined Space.
The information on pages 4 through 6 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 com-
bustion and ventilation. However, in build- ings 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 continuous water vapor retarder
with a rating of one perm (6x10"" per pa-sec-m 2) or less with openings gnsketed or sealed and
b.weather stripping has been added
on openable windows and doors
and
e. caulking or sealants are applied to
areas such as joints around window and door frames, between sole plates and floors, between
wall-ceillng joints, between wall
panels, at penetrations for plumbing, electrical, and gas fines,
and at other openings.
If your home meets all of the three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors,
page 6.
If your home does not meet all of the three criteria above, proceed to page 5.
Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ223.1,
1992 Section 5.3) defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btuper 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.
*Adjoining rooms are communicating only
if there are doorless passageways or ventila-
tion grills between them.
_WARNING: Ifthearea inwhich
the heater may be operated is smaller than that defined as an
unconfined space, provide ad-
equate combustion and ventila- tion air by one of the methods
described in the National Fuel
Gas Code, ANSI Z223.1, 1992, Section 5.3.

DETERMINING 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 wilt 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 20ft. (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/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 + 33,000 Btu/Hr Total = 73,000 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/I-Ir 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/Hr (maximum the space can support)
73,000 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 adjoining
room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6. 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/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.

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 pro- vide 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 1and 2, Figure 2). You can also
remove door into adjoining room (see op- tion 3, Figure 2). Follow the National Fuel
Gas Code NFPA 54/ANSI Z223.1, Section
5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
_kWARNING:Rework work-
sheet, adding the space of the adjoining unconfined space. The
combined spaces must have enough fresh air to supply all appliances in both spaces.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two per-
manent openings: one within 12" of the ceiling and one within 12" of the floor.
Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces.
IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air entering the attic will activa_: the power
vent.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
Note: When used as a vented beater, appli-
ance must be installed only in a solid-fuel burning fueplace with a working flue and
constructed of non combustible material. ffyour heater is amanually 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.
Ifreasons number 1 or 2 above apply to you, you must permanently open chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, page
25). 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 permanent
flue opening will be maintained at all times.

Before installing heater, make sure you have
the items listed below.
external regulator (supplied by installer, see page 12)
piping (check local codes)
sealam (resistant to propane/LP gas)
manual shutoff valve *
test gauge connection *
sediment trap
tee joint
pipe wrench
An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Pur- chase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See
Accessories, page 25. Continued

The installer must supply an external regu- lator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14
inches of water, ffyou do not reduce incom- ing 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.
_IL WARNING: Never connect
heater to private (non-utility) gas wells. This gas is commonly
known as wellhead gas.
_k 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 of1/2"
diameter or greater 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 118" NPT tap.
Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from
heater (see Figure 14). Apply pipe joint sealant lighdy 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 joint seal-
ant that is resistant to liquid pe- troleum (LP) gas.
Install sediment trap in supply line as shown in Figure 14. Locate sediment trap where it is within reach for cleaning. Locate sedi-
ment 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.

Fireplace
If your log set cycles to pilot, but the room temperature drops to a lower than ideal comfort level before the log set comes back on, you may want to reposi- tion the thermostat sensing bulb.
The thermostat sensing bulb is located on the gas valve assembly. This location al-
lows the thermostat to keep the room tem-
perature at an ideal comfort level for most
fireplace applications. For positioning the thermostat sensing bulb elsewhere, an ad-
hesive-backed mounting clip has been pro- vided.
Tools needed: 5/16" hex driver or socket
1. Locate the gas valve assembly and
thermostat sensing bulb (see Figure 29).
2. The adhesive-backed mounting clip (see Figure 30) is attached to the
thermostat sensing bulb. Remove the adhesive-backed mounting clip.
3. With 5/16" hex driver or socket, loosen the thermostat screw. Carefully slide
the thermostat sensing bulb out of the
retaining clamp (see Figure 31).
Note: Do not remove the screw. Make sure you tighten the screw after
removing the thermostat sensing bulb.
4.
IMPORTANT: Do not force or bend the thermostat sensing bulb or capillary. A
crimped capillary will not allow ther- mostat to operate properly. It cannot be
repaired, the valve must be replaced. The thermostat sensing bulb may be
located to the lower right front side of fireplace. Determine location of sens- ing bulb, but do not mount sensing bulb until step 5. If you have a masonry fireplace, see Figure 32 for location.
