COMBUSTION AND
VENTILATION
The following are excerpts from National
Fuel Gas Code ANSI Z223.1/NFPA 54, Sec-
tion5.3, AirforCombustionandVentilation.
WARNING: This heater shall

or unusually tight construction
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.
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.
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weather strip and caulk around windows and
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
* Adjoining rooms are communicating only
iftherearedoorlesspassagewaysorventila-
tion grills between them.
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:
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 com-
bustion and ventilation.
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
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.
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-
tions for plumbing, 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
three criteria above, proceed to Deter-

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.

* 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)
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 cansupport.
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 the area in which the heater may be operated is smaller than that defined as an unconfined space
or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of
themethodsdescribedintheNationalFuelGasCode, ANSIZ223.1/NFPA54, Section5.3orapplicablelocalcodes.

from going into pipe. Excess sealant in pipe
could result in clogged heater valves.
Installation Items Needed
6. Carefully remove logs without moving
heater base.
Beforeinstallingheater,makesureyouhave
the items listed below.
7. Mark screw locations through one hole
on each side of the mounting bracket
(see Figure 12). If installing in a brick-
bottom fireplace, mark screw locations
in mortar joint of bricks.
• external regulator (supplied by installer,
see above)
WARNING:Usepipejointseal-
ant that is resistant to liquid pe-
troleum (LP) gas.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
8. Remove heater base from fireplace. If
installing optional control accessories,
do so at this time. Follow all directions
provided with accessory.
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
from going into heater controls. If sediment
trap is not installed or is installed wrong,
heater may not run properly.
9. Drill holes at marked locations using
3/16" drill bit.
• tee joint
• pipe wrench
10. Attach base assembly to fireplace floor
using two masonry screws (in hardware
package).
* ACSAdesign-certifiedequipmentshutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection.
Masonry Screw
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incominggaspressuretobetween11and14
inches of water. If you 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.
CAUTION: Avoid damage to
control. Hold fitting with wrench
when connecting it to gas piping
and/or fittings.

wise
to the OFF position.
WARNING: If you do not fol-
low these instructions exactly, a
fireorexplosionmayresultcaus-
ing property damage, personal
injury or loss of life.
5. Wait five (5) minutes to clear out any
gas. Then smell for gas, including
near the floor. If you smell gas,
STOP! Follow “B” in the safety in-
formation, column 1. If you don’t
smell gas, go to the next step.
A. This appliance has a pilot which must
be lighted by hand. When lighting the
pilot, follow these instructions exactly.
• You must operate this heater
withafireplacescreeninplace.
Make sure fireplace screen is
closed before running heater.
6. Press in and turn control knob coun-
terclockwise
to the PILOT
position. Press in control knob for
five (5) seconds (see Figure 20).
B. BEFORE LIGHTING smell all
around the appliance area for gas. Be
sure to smell next to the floor because
some gas is heavier than air and will
settle on the floor.
Note: You may be running this
heater for the first time after hook-
ing up to gas supply. If so, the con-
trol knob may need to be pressed in
for 30 seconds or more. This will al-
low air to bleed from the gas system.
NOTICE: During initial operation
of new heater, burning logs will
give off a paper-burning smell.
Open damper or window to vent
smell.Thiswillonlylastafewhours.
WHAT TO DO IF YOU SMELL
GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do
not use any phone in your building.

into the room. However, there may be
times you will desire the full flames of the
HI heat setting but will find the heat
output excessive. You can open the chim-
ney damper (if you have one) fully or
partially to release some of the heat.
Note: If pilot does not stay lit, con-
tact a qualified service person or gas
supplier for repairs. Until repairs are
made, light pilot with match. To light
pilot with match, see Manual Light-
ing Procedure on page 15.
C. Use only your hand to push in or turn
the gas control knob. Never use tools.
If the knob will not push in or turn
by hand, don’t try to repair it, call a
