AIR FOR COMBUSTION AND
VENTILATION
Today’s homes are built more energy efficient than ever. New
materials,increased insulation,and newconstructionmethods help
reduce heat loss in homes. Home owners weather strip and caulk
aroundwindows anddoors tokeepthe coldair outand thewarm 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.
Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances
drawairfromthehousetooperate.Youmustprovideadequatefresh
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, 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 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.
WARNING: This heater shall not be installed in a
confined space or unusually tight construction un-
less provisions are provided for adequate combus-
tion and ventilation air. Read the following instruc-
tionstoinsureproperfreshairforthisandotherfuel-
burning appliances in your home.
Unusually tight construction is defined as construction
where:
a. walls and ceilings exposedtotheoutsideatmosphere
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,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 additional fresh air. See
Ventilation Air
From Outdoors , page 7 .
If your home does not meet all of the three criteria above,
proceed to Determining Fresh-Air Flow for Fireplace Lo-
cation on page 6.
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
furnishedwith doors,areconsidered apartof theunconfinedspace.
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.

DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space
Usethisworksheettodetermineifyouhaveaconfined or unconfined space.
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 18 ft. (width) x 8 ft. (ceiling
height) = 2880 cu. ft. (volume of space)
Ifadditionalventilationtoadjoiningroomissuppliedwith grills or 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: 2880 cu. ft. (volume of space) x 20 = 57,600 (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: 57,600 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:
WARNING: If the area in which the heater may be
operated is smaller than that defined as an uncon-
fined space or if the building is of unusually tight
construction,provideadequatecombustionandven-
tilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec-
tion 5.3 or applicable local codes .
A. Rework worksheet, adding the space of an adjoining room. If the
extra space provides an unconfined space, remove door to adjoining
roomor add ventilation grillsbetweenrooms.SeeVentilationAir From
Inside Building.
B. Vent room directly to the outdoors. See Ventilation Air From Out-
doors, page 7.
C. Installa lower Btu/Hrheater, if lowerBtu/Hrsize 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.

commonly known as wellhead gas.
INSTALLING GAS PIPING TO FIREPLACE
LOCATION
WARNING: For propane/LP units, never connect
fireplace directly to propane/LP supply. This fire-
place requires an external regulator (not supplied).
Install the external regulator between the heater and
propane/LP supply.
Installation Items Needed
Beforeinstallingfireplace,makesureyouhavetheitemslistedbelow.
• externalregulator (suppliedbyinstaller,for propane/LPunits only)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by lo-
cal codes) (not provided)
* A CSA design-certified equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA design-certified equipment shutoff valve from
your dealer. See Accessories, pages 30 and 31.
For propane/LP units, the installer must supply an external regula-
tor. 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 point-
ing down as shown in Figure 14, page 12. Pointing the vent down
protects it from freezing rain or sleet.

WARNING:Usepipejoint sealant that isresistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in supply line as
showninFigure15.Locatesedimenttrapwhereitiswithinreachfor
cleaning.Installinpipingsystembetweenfuelsupplyandfireplace.
Locatesedimenttrap wheretrapped matter 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.
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 14).
IMPORTANT: Install equipment shutoff valve in an accessible
location. The equipment shutoff valve is for turning on or shutting
off the gas to the appliance.
Checkyourbuildingcodesforanyspecialrequirementsforlocating
equipment shutoff valve to fireplaces.
ApplypipejointsealantlightlytomaleNPTthreads.Thiswillprevent
excess sealant from going into pipe. Excess sealant in pipe could
result in clogged fireplace valves. Never use sealant on flare threads.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
diameter or greater to allow proper gas volume to
fireplace. If pipe is too small, undue loss of volume
will occur.

B. Using Hand-Held Wireless Remote Control
1. Set manual ignition bypass switch on control panel to OFF
position (automatic ignition position).
2. Wait five (5) minutes to clear out any gas. Smell for gas
around heater and near floor. If you smell gas, STOP! Fol-
low “B” in the safety information on warnings plate. If you
don’t smell gas, go to the next step.
3. Point remote control toward the lower front of fireplace
and push both buttons at the same time. Hold for 6 sec-
onds. The gas valve will open and electronic ignition will
begin sparking to light the pilot. Note: You will be able to
hear a clicking sound during this process. LED on wall
switch will light.
Note: You may be running this heater for the first time
after connecting to gas supply or at the start of your heat-
ing season. If so, the ON button may need to be pressed
again. This will allow air to bleed from gas system. If sev-
eral attempts to light pilot fail, contact a qualified service
person or gas supplier for repairs. Until repairs are made,
light and operate manually (see Manual Lighting Instruc-
tions for Electrical Power Outage).
4. When pilot flame is lit, the thermocouple is heated by the
flame. When thermocouple becomes hot (5 to 15 seconds),
main burner will automatically light on high flame.

PILOT FLAME PATTERN
Figure41 onpage 21showsacorrectpilot flamepattern. Figure42,
page 21, shows an incorrect pilot flame pattern. The incorrect pilot
flameisnot touchingthethermocouple.Thiswillcausethe thermo-
couple to cool. When the thermocouple cools, the heater will shut
down.
If pilot flame pattern is incorrect, as shown in Figure 42, page 21
• turn heater off (see To Turn Off Gas to Appliance, page 19 or col-
umn 1)
• see Troubleshooting, pages 23 through 25
Note: The pilot flame on natural gas units will have a slight curve,
but the flame should be blue and have no yellow or orange color.
