AIR FOR COMBUSTION AND
VENTILATION
Today’s homes are built more energy efficient than ever. New mate-
rials,increased insulation, andnewconstructionmethods helpreduce
heat loss in homes. Home owners weather strip and caulk around
windowsanddoorstokeepthecoldairoutandthewarmairin.During
heatingmonths,homeownerswanttheirhomesasairtightaspossible.
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.
Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances
drawairfromthehousetooperate.Youmustprovideadequatefresh
air for these appliances. This will insure proper venting of vented
fuel-burning appliances.
PRODUCT FEATURES
OPERATION
This vent-free fireplace is clean burning. It requires no outside
venting. There is no heat loss out a vent or up a chimney. Heat is
generated by both realistic flames and glowing embers. When used
without the blower, the fireplace requires no electricity making it
ideal for emergency backup heat.
SAFETY DEVICE
Thisfireplace has apilotwith anOxygen DepletionSensing(ODS)
safety shutoff system. The ODS/pilot is a required feature for vent-
free room heaters. The ODS/pilot system shuts off the fireplace if
there is not enough fresh air.

DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space
Usethis worksheetto determineifyou haveaconfined orunconfinedspace.
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining
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)
Ifadditional ventilationtoadjoining roomissupplied withgrillsor open-
ings, 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 com-
bustion air from the outdoors and vents to the outdoors.
Example:
Gas water heater _____________ Btu/Hr
Vent-free heater + _____________ Btu/Hr
Total = _____________ Btu/Hr
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)
73,000 Btu/Hr (actual amount of Btu/Hr used)
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, ANSI
Z223.1/NFPA 54, 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 4 through 6 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 construc-
tion where:
a. walls and ceilingsexposedto theoutsideatmosphere
have a continuous water vapor retarder with a rating
of one perm (6 x 10-11 kg per pa-sec-m2) or less with
openings gasketed or sealed and
b. weather stripping has been added on openable win-
dows and doors and
c. caulking or sealants are applied to areas such as
joints around window and door frames,between sole
platesandfloors,betweenwall-ceilingjoints,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 additional fresh air. See Ventilation Air
From Outdoors , page 6 .
Ifyourhome does notmeetall ofthethree criteria above,
proceed to Determining Fresh-Air Flow for Fireplace
Location , column 2.
Confined Space and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 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 unconfined space as
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper
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 installed*, through openings not
furnishedwithdoors,are considereda part ofthe unconfinedspace.
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.

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 3). You can also remove door into
adjoining room (see option 3, Figure 3). Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion
and Ventilation for required size of ventilation grills or ducts.

Before installing fireplace, make sure you have the items listed
below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap (optional)
• tee joint
• pipe wrench
* ACSAdesign-certifiedequipmentshutoffvalvewith1/8"NPTtap
is an acceptable alternative to test gauge connection. Purchase the
optional CSA design-certified equipment shutoff valve from your
dealer. See Accessories, pages 32 and 33.
Theinstallermustsupplyanexternalregulator.Theexternalregulator
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
externalregulatorwiththeventpointingdownasshowninFigure17.
Pointing the vent down protects it from freezing rain or sleet.
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
Figure 18 - Gas Connection
* Purchase the optional CSA design-certified equipment shutoff
valve from your dealer. See Accessories, pages 32 and 33.
** Minimum inlet pressure for purpose of input adj.
Installation must include an equipment 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 fireplace (see Figure 17).
WARNING:Use pipejointsealant thatisresistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in supply line as
showninFigure18.Locatesedimenttrapwhereitiswithinreachfor
cleaning.Installinpipingsystembetweenfuelsupplyandfireplace.
Locatesediment trapwhere trappedmatter isnot likely tofreeze. A
sediment trap traps moisture and contaminants. This keeps them
from going into fireplace gas controls. If sediment trap is not
installed or is installed wrong, fireplace may not run properly.

CLEANING BURNER INJECTOR HOLDER
AND PILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to mix with
thegas.Thisprovidesacleanburningflame.Keeptheseholesclearof
dust, dirt, lint, and pet hair. Clean these air inlet holes prior to each
heatingseason.Blockedairholeswillcreatesoot.Werecommendthat

inspected yearly by a qualified service person.
We also recommend that you keep the burner tube and pilot
assembly clean and free of dust and dirt. To clean these parts we
recommendusingcompressedairnogreaterthan30PSI.Yourlocal
computer store, hardware store, or home center may carry com-
pressed air in a can. You can use a vacuum cleaner in the blow
position. If using compressed air in a can, please follow the direc-
tionsonthecan.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 36).
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
