AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a
room or space unless the required volume of indoor
combustion air is provided by the method described
in the National Fuel Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas Code, or applicable
local codes. Read the following instructions to ensure proper fresh air for this and other fuel-burning
appliances in your home.
Today’s homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help
reduce heat loss in homes. Homeowners apply weather strip and
caulk around windows and doors to keep the cold air out and the
warm air in. During heating months, homeowners 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.
Exhaust fans, some fireplaces, clothes dryers and some fuel-burning
appliances draw air from the house to operate. You must provide
adequate fresh air for these appliances. This will ensure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, ANSI
Z223.1/NFPA 54, 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 6-7 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.
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
-11
(6 x 10
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, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations
for plumbing, electrical and gas lines and at other openings.
If your home meets all three criteria above, you must provide
additional fresh air. See Ventilation Air From Outdoors, Page 7.
If your home does not meet all three criteria above, proceed to
Determining Fresh-Air Flow For Heater Location.
kg per pa-sec-m2) or less with openings gasketed or
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/ NFPA54 allows two
methods for determining whether the space in which the heater is
being installed is confined or unconfined space. The standard method
defines a confined space as a space whose volume is less than 50
cubic feet per 1,000 Btu/hr (4.8 m3 per kw) of the aggregate input
rating of all appliances installed in that space and an unconfined
space as a space whose volume is not less than 50 cubic feet per
1,000 Btu/hr (4.8 m3 per 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
furnished with doors, are considered a part of the unconfined space.
Where the air infiltration rate of a structure is known, the Known
Air Infiltration Rate Method may be used. Follow The National Fuel
Gas Code, ANSI Z223.1/NFPA 54 to use this method to determine
if the space is confined or unconfined.
* 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 Using
the Standard Method
Use this work sheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install fireplace 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 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 fireplace ________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.
Example:Gas water heater 40,000 Btu/Hr
Vent-free fireplace + 33,000 Btu/Hr
Total = 73,000 Btu/Hr

Compare the maximum Btu/Hr the space can support with the
actual amount of Btu/Hr used.
______ Btu/Hr (maximum can support)
______ Btu/Hr (actual amount 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.
B. Vent room directly to the outdoors. See Ventilation Air From
Outdoors.
C. Install a lower Btu/Hr fireplace, 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 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 2). You can also remove door into adjoining room
(see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and Ventilation for required
size of ventilation grills or ducts.
WARNING: If the area in which the heater may
be operated does not meet the required volume for
indoor combustion air, combustion and ventilation air
shall be provided by one of the methods described
in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable
local codes.
Figure 2 - Ventilation Air from Inside Building
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent 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. Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for required size of
ventilation grills or ducts.
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 activate the power vent.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED
OPERATION
NOTE: When used as a vented heater, appliance must be installed only
in a solid-fuel burning fireplace with a working flue and constructed
of noncombustible material.
For Massachusetts Residents Only: Installation of this vented gas
log set in the Commonwealth of Massachusetts requires the damper
be permanently removed or welded in the fully open position.
If your heater is a manually-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.
If reasons number 1 or 2 apply to you, you must permanently open
chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, Page 28). This will ensure vented
operation (see Figure 10). The damper clamp will keep damper
open. Installation instructions are included with clamp accessory.

INSTALLING HEATER BASE ASSEMBLY
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 or log
misplacement.
WARNING: If installing in a sunken fireplace,
special care is needed. You must raise the fireplace
floor to allow access to heater control panel. This will
ensure adequate air flow and guard against sooting
and controls being damaged. Raise fireplace floor
with noncombustible material. Make sure material
is secure.
CAUTION: Do not pick up heater base assembly
by burners. This could damage heater. Only handle
base assembly by grates.
IMPORTANT: Make sure the heater burners are level. If heater is not
level, heater will not work properly.

WARNING: This appliance requires a 3/8" NPT
(National Pipe Thread) inlet connection to the pressure regulator.
WARNING: A qualified service person must connect
heater to gas supply. Follow all local codes.
CAUTION: Never connect propane/LP fireplace directly to the propane/LP supply. This heater requires an
external regulator (not supplied). Install the external
regulator between the heater and propane/LP supply.
Installation Items Needed
Before installing heater, 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
• tee joint
• pipe wrench

Figure 12 - Attaching Base to Fireplace Floor
For propane/LP units, the installer must supply an external regulator.
The external regulator will reduce incoming gas pressure. You must
reduce incoming gas pressure to between 11" and 14" of water. If
you do not reduce incoming 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.

INSTALLATION Continued
WARNING: Never connect natural gas fireplace to
private (non-utility) gas wells. This gas is commonly
known as wellhead gas.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to heater.
If pipe is too small, undue loss of volume will occur.
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 heater (see Figure 14).
IMPORTANT: Install equipment shutoff valve in an accessible loca-
tion. The equipment shutoff valve is for turning on or shutting off
the gas to the appliance.
Check your building codes for any special requirements for locating
equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male NPT threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe could
result in clogged heater valves.
CAUTION: Avoid damage to regulator. Hold gas
regulator with wrench when connecting it to gas piping and/or fittings.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections,
internal and external to unit, for leaks after installing
or servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for
a leak. Apply a noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak. Correct all
leaks at once.
CAUTION: Make sure external regulator has been
installed between propane/LP supply and heater. See
guidelines under Connecting to Gas Supply, Page 12.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in supply line as
shown in Figure 14. 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 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.

INSPECTING BURNERS
CLEANING AND MAINTENANCE
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 31 shows a correct pilot flame pattern. Figure 32 shows an
incorrect pilot flame pattern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermocouple to cool. When
the thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 32
• turn heater off (see To Turn Off Gas to Appliance, Page 18)
• see Troubleshooting, Page 21
NOTE: The pilot flame on natural gas units will have a slight curve,
but flame should be blue and have no yellow or orange color.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the fitting at the
burner entrance. These holes may become blocked with dust or lint.
Periodically inspect these holes for any blockage and clean if needed.
Blocked air holes will create soot.

WARNING: Turn off heater and let cool before
cleaning.
CAUTION: You must keep control areas, burners
and circulating air passageways of heater clean.
Inspect these areas of heater before each use. Have
heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due
to excessive lint from carpeting, pet hair, bedding
material, etc.
WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in sooting and property damage.
BURNER ORIFICE 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 create soot. We recommend
that you clean the unit every three months during operation and have
heater 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
recommend using compressed air no greater than 30 PSI. Your
local computer store, hardware store or home center may carry
compressed air in a can. If using compressed air in a can, please
follow the directions on the can. If you don’t follow directions on
the can, you could damage the pilot assembly.
Figure 32 - Incorrect Pilot Flame Pattern (Your pilot may vary
from pilots shown)
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 become blocked
by debris or rust, with no flame present. If so, turn off heater and let
cool. Remove blockage. Blocked burner flame holes will create soot.
