PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code ANSI Z223.1/NFPA 54, Sec-
tion5.3,AirforCombustionandVentilation.
Allspacesinhomesfallintooneofthethree
following ventilation classifications:
1. Unusually Tight Construction
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
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. walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6 x 10-11 kg
per pa-sec-m2) or less with open-
ings 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, be-
tween sole plates and floors,be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsforplumbing,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 6.
If your home does not meet all of the
threecriteria above,proceedto Deter-
miningFresh-AirFlowForHeaterLo-
cation, page 5.
AIR FOR
COMBUSTION AND
VENTILATION
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weatherstripandcaulkaround windows and
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient,yourhomeneedstobreathe.Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaustfans,fireplaces,clothesdryers,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.
WARNING: This heater shall

unless provisions are provided
foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Confined and Unconfined Space

DETERMINING FRESH-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: Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween
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. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.
_________________ (volume of space) x 20 = (maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x 20 = 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
* 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/Hr (maximum the space can support)
71,500 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
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 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.

WARNING: If installing in a
sunken fireplace, special care is
needed. You must raise the fire-
place floor to allow access to
heater control panel. This will in-
sureadequateair flowand guard
against sooting and controls be-
ingdamaged.Raisefireplace floor
with noncombustible material.
Make sure material is secure.
CAUTION: Do not pick up
heater base assembly by the
burner. This could damage
heater.Onlyhandle base assem-
bly by grates.
WARNING: You must secure
this heater to fireplace floor. If
not, heater will move when you
adjust controls. Moving heater
may cause a gas leak.
IMPORTANT: Makesuretheheaterburner
is level. If heater is not level, heater will not
work properly.
Installation Items Needed
• hardwarepackage (providedwith heater)
• approvedflexible gas hose(notprovided)
(if allowed by local codes)
• sealant (resistant to propane/LP gas, not
provided)
• electric drill with 3/16" drill bit (metal
or masonry as applicable)
• flathead screwdriver
1. Apply pipe joint sealant lightly to male
threads of the fitting to be threaded into
gas control. Connect approved flexible
gas hose to gas control fitting in heater
(see Figure 11). IMPORTANT: Hold

INSTALLING DAMPER
CLAMP ACCESSORY FOR
VENTED OPERATION
Note: When used as a vented heater, appli-
ance must be installed only in a solid-fuel
burning fireplace with a working flue and
constructed of noncombustible material.
Ifyourheaterisamanually-controlledmodel,
youmay use thisheater asa vented product.
There are three reasons for operating your
heater in the vented mode.
1. The fireplace does not meet the clear-
ance to combustibles requirements for
vent-free operation.
2. State or local codes do not permit vent-
free operation.
3. You prefer vented operation.
Ifreasonsnumber1or2aboveapplytoyou,
you must permanently open chimney flue
damper.Youmustinstall the damperclamp
accessory (to order, see Accessories, page
21). 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
flueopeningwillbe maintained atalltimes.

WARNING:Aqualifiedservice
person must connect heater to
gassupply.Followalllocalcodes.
CAUTION: Never connect
heaterdirectly tothe propane/LP
supply. This heater requires an
externalregulator(notsupplied).
Install the external regulator be-
tweentheheaterandpropane/LP
supply.
Installation Items Needed
Beforeinstallingheater,makesureyouhave
the items listed below.
• external regulator (supplied by installer,
see above)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* ACSAdesign-certifiedequipmentshutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incominggaspressuretobetween11and14
inchesofwater.Ifyoudonotreduceincom-
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.

tap. Locate NPT tap within reach for test
gauge hook up. NPT tap must be upstream
from heater (see Figure 14, page 12).
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
yourlocalcodes.Usepipeof1/2"
diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.
We recommend that you install a sediment
trap in supply line as shown in Figure 14,
page 12. Locate sediment trap where it is
within reach for cleaning. Install in piping
system between fuel supply and heater.
Locate sediment trap where trapped matter
is not likely to freeze. A sediment trap traps
moistureandcontaminants.Thiskeepsthem
fromgoing intoheater controls.If sediment
trap is not installed or is installed wrong,
heater may not run properly.
WARNING:Usepipejointseal-
ant that is resistant to liquid pe-
troleum (LP) gas.
CAUTION: Avoid damage to
control. Hold fitting with wrench
when connecting it to gas piping
and/or fittings.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heaterinspectedyearlybyaquali-
fied service person. Heater may
needmorefrequentcleaningdue
to excessive lint from carpeting,
bedding material, pet hair, etc.
LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 13, to properly re-
place logs.
• Replace log(s) if broken or chipped
(dime-sized or larger).
MAIN BURNER
Periodically inspect all burner flame holes
with the heater running. All slotted burner
flame holes should be open with yellow
flame present. All round burner flame holes
should be open with a small blue flame
present. Some burner flame holes may be-
comeblockedbydebrisorrust,withnoflame
present. If so, turn off heater and let cool.
Remove blockage. Blocked burner flame
holes will create soot.
CLEANING BURNER
INJECTOR HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This
provides a clean burning flame. Keep these
holes clear of dust, dirt, lint, and pet hair.
Clean these air inlet holes prior to each
heating season. Blocked air holes will cre-
ate soot. We recommend that you clean the
unit every three months during operation
andhave heater inspectedyearly bya quali-
fied service person.
Wealsorecommendthatyoukeeptheburner
tubeandpilotassemblycleanandfreeofdust
anddirt.To clean theseparts werecommend
usingcompressed airno greater than30 PSI.
Yourlocalcomputerstore,hardwarestore,or
home center may carry compressed air in a
can. You can use a vacuum cleaner in the
blow position. If using compressed air in a
can, please follow the directions on the can.
Ifyoudon'tfollowdirectionsonthecan, you
could damage the pilot assembly.
1. Shut off the unit, including the pilot.
Allow the unit to cool for at least thirty
minutes.
2. Inspect burner, pilot, and primary air
inlet holes on injector holder for dust
and dirt (see Figure 26).
3. Blow air through the ports/slots and
holes in the burner.

4. Check the injector holder located at the
end of the burner tube again. Remove
any large particles of dust, dirt, lint, or
pet hair with a soft cloth or vacuum
cleaner nozzle.
5. Blow air into the primary air holes on
the injector holder.
6. In case any large clumps of dust have
now been pushed into the burner repeat
steps 3 and 4.
Clean the pilot assembly also. A yellow tip
on the pilot flame indicates dust and dirt in
the pilot assembly. There is a small pilot air
inlet hole about two inches from where the
pilot flame comes out of the pilot assembly
(see Figure 27). With the unit off, lightly
blowair through theairinlet hole. Youmay
