SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensing (ODS)
safety shutoff system. The ODS/pilot is a required feature for ventfree room heaters. The ODS/pilot shuts off the heater if there is not
enough fresh air.
PIEZO IGNITION SYSTEM
This heater has a piezo Igniter. This system requires no matches,
batteries or other sources to light heater.
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 5 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 construction where:
a. walls and ceilings exposed to the outside atmosphere have a
continuous water vapor retarder with a rating of one perm (6 x
-11
10
kg per pa-sec-m2) or less with openings 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, 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 6.
If your home does not meet all three criteria above, proceed to
Determining Fresh-Air Flow For Heater Location.
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 per hour (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
per hour (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 heater 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

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.
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.
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 31). This will ensure vented operation
(see Figure 9, page 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.

CONNECTING TO GAS SUPPLY
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
* An equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional equipment
shutoff valve from your dealer.
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 12. Pointing the vent down protects it from freezing
rain or sleet.

Regulator
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 13).
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.
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.
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 13. 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.
