Preparing for Installation
WATER VAPOR IS A BY-PRODUCT OF UNVENTED ROOM HEATERS
Gas combustion creates water vapor as a by-product. Unvented room heaters create about one (1) ounce (30
ml) of water for every 1,000 BTUs (0.3 kW) of gas input per hour. An unvented room heater is recommended
as a supplemental heat source for a single room rather than as a primary heat source for an entire house. The
water vapor does not typically create a problem. In most cases, the water vapor enhances the low humidity
conditions that are typical of cold weather.
Keep these points in mind so that the water vapor does not create a problem:
•The heater must be the proper size for the application. Provide adequate combustion air and circulation air.
• In humid environments, use a dehumidifier to help lower the amount of water vapor in the air.
• Do not use an unvented room heater as your primary heat source.
AIR FOR COMBUSTION AND VENTILATION
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, ANS Z223.1/NFPA 54, the International Fuel
Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
Spaces in homes can be divided into these ventilation classifications:
•Unusually Tight Construction
• Unconfined Space
• Confined Space
The information on pages 7–9 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space:
A confined space has a volume less than 50 cu. ft. per 1,000 BTU/hr (4.8 m3 per kW) of the total input rating
of all appliances installed in that space. An unconfined space has a volume not less than 50 cu. ft. per
1,000 BTU/hr (4.8 m3 per kW) of the total input rating of all appliances installed in that space. Rooms that
are directly connected to the space in which the appliances are installed*, through openings that do not
have doors, are considered a part of the unconfined space.
Do not install this heater in a confined space or unusually tight construction unless you provide provisions
for adequate combustion and ventilation air.
*Adjoining rooms are directly connected only if there are doorless passageways or ventilation grills between them.
Unusually Tight Construction:
Doors and windows may leak air that provides enough fresh air for combustion and ventilation. However,
you must provide additional fresh air in buildings of unusually tight construction. Unusually tight
construction is defined as construction that meets the following criteria:
A. Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a
rating of one perm or less with openings that are gasketed or sealed.
B. Doors and windows that can be opened have weather stripping.
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 residence meets all the above criteria, additional fresh air must be provided. See VENTILATION AIR
FROM OUTDOORS on page 9 for more information. If your residence does not meet those three criteria,
continue to DETERMINING FRESH-AIR FLOW FOR THE HEATER LOCATION.

Preparing for Installation (cont.)
DETERMINING FRESH-AIR FLOW FOR THE HEATER LOCATION
Determining if You Have a Confined or Unconfined Space:
Use the below information to determine if you have a confined or unconfined space. Your space includes
the room in which you will install the heater plus any other rooms that are directly connected and have
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space. Length × Width × Height = cu. ft. (volume of space)
• Example: 20 ft. (length) × 16 ft. (width) × 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
If additional ventilation to adjoining room(s) is supplied with grills or openings, add the volume of these
rooms to the total volume of your space.
2. Divide the space’s volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.
_______ (volume of space) ÷ 50 cu. ft. = (maximum BTU/hr the space can support)
•Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 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 Example:
Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr
Total = ____BTU/hr Total = 56,000 BTU/hr
*Do not include direct-vent gas appliances. Direct-vent appliances draw combustion air from outdoors
and vent 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) 56,000 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. Add the space of an adjoining room and rework the above information. If the extra space creates an
unconfined space, remove the door to the adjoining room or add ventilation grills between rooms.
See VENTILATION AIR FROM INSIDE A BUILDING, page 9.
B. Vent the room directly to the outdoors. See VENTILATION AIR FROM OUTDOORS, page 9.
C. Install a heater that uses less BTUs/hr if the lower BTUs/hr creates an unconfined space. If the actual BTU/
hr used is less than the maximum BTU/hr the space can support, the space is an unconfined space. In
this case, no additional fresh air ventilation is needed.

Vent-Free Gas Log Heater User’s Manual
Preparing for Installation (cont.)
If the area in where the heater operates does not meet the required volume for
indoor combustion air, you must provide combustion and ventilation air 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.
WARNING
VENTILATIONAIRFROMINSIDEABUILDING
Fresh air comes from a connected unconfined space.
You must provide two permanent openings when
ventilating to a connected unconfined space, one of
which that’s within 12" of the wall that connects the
two spaces (see options 1 and 2, Fig. 1). You may also
remove the door into the adjoining room (see option 3,
Fig. 1). Follow the National Fuel Gas Code NFPA 54/ANS
Z223.1 for the required size of ventilation grills or ducts.
VENTILATION AIR FROM OUTDOORS
Extra fresh air is provided via ventilation grills or
ducts. You must provide two permanent openings:
one within 12" of the ceiling and one within 12" of
the floor. They must connect directly to the outdoors
or spaces that open to the outdoors. Such spaces
may include attics or crawl spaces. Follow the
National Fuel Gas Code NFPA 54/ANS Z223.1 for the
required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or
outlet air into an attic if the attic has a thermostat-
controlled power vent. The power vent will be
activated by heated air that enters the attic. You must
add the space of the connected unconfined space
and rework the information on page 8. The combined
spaces must have enough fresh air to supply all
appliances in both spaces.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
NOTE: When used as a vented heater, the heater must
be installed only in a solid-fuel burning fireplace with a
working flue constructed of noncombustible material.
You may use this heater as a vented product. When
used as a vented decorative appliance, use of the
thermostat function is prohibited—operate manually
only. There are three reasons for operating your heater
as a vented model:
1. The fireplace does not meet the clearance requirements
for vent-free operation.
2. State or local codes do not permit vent-free operation.
3. You prefer vented operation.
Any chimney damper must be fixed in a manner that will maintain the minimum permanent vent opening
at all times. Installing a damper clamp to prevent the damper from accidentally closing is recommended
(see Fig. 9).

CONNECTING TO A GAS SUPPLY
The installer must supply an external regulator for liquid propane. For natural gas, the gas supplier supplies
the external regulator. The external regulator reduces incoming gas pressure, and the pressure must be
reduced to between 11" and 14" of water column for propane and between 6" and 10.5" of water column
for natural gas. Heater regulator damage could occur if the pressure of the incoming gas is not reduced.
Install the external regulator with the vent pointing down as shown in Fig. 10. The purpose of pointing the
vent down is to protect it from freezing rain or sleet.
*The equipment shutoff valve can be purchased from your local home center store.
A qualified service technician must connect heater to gas supply. Follow all local codes.
WARNING
Never connect the heater directly to the gas supply. This heater requires an external
regulator (not supplied). The external regulator between the gas supply and heater
must be installed. Your gas supplier provides the external regulator for natural gas.
CAUTION
Never connect the heater to private/non-utility gas wells (commonly known as
wellhead gas).

IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is
for turning on or shutting off the gas to the heater. Apply pipe joint sealant lightly to the male threads.
This prevents excess sealant from going into the pipe. The heater valves may become clogged if excess
sealant gets into the pipes.
Use only new black iron or steel pipe. Internally tinned copper tubing may be used
in certain areas, depending on your local codes. Use pipe of 1/2" diameter or greater
to allow proper volume gas to heater. If the pipe is too small, loss of pressure will occur. Installation must
include an equipment shutoff valve, union, and plugged 1/8" NPT tap. The NPT tap must be located within
reach for the test gauge hook up and be upstream from heater (see Fig. 11).

Vent-Free Gas Log Heater User Manual
Installation (cont.)
Use pipe joint sealant that is resistant to gas (propane or NG). We recommend that you
install a sediment trap in a supply line, which traps moisture and contaminants. The
sediment trap should be located within reach for cleaning and where it is not likely to freeze. Install it in the
piping system between the fuel supply and heater. This keeps contaminants from getting into the heater
controls. The heater may not run properly if the sediment trap is not installed or is installed incorrectly.
CAUTION
Avoid damage to the regulator. Hold the gas regulator with a wrench when connecting
into gas piping and/or fittings. NG Models: 6" to 10.5 W.C. /11" to 14" W.C..
Your gas supplier provides an external regulator for natural gas.
CAUTION
INSTALLATION ITEMS NEEDED (NOT PROVIDED):
•8" Adjustable Wrench
•8" Pipe Wrench
• 3/8" Flexible Gas Line (24" Min.) or 1/2" Black Pipe
• 90 Deg. 3/8 NPT x 3/8" Flare Fitting or 3/8" Street Elbow
• Sealant (Resistant to natural or propane gas)
•Shutoff Valve
1. Depending on where your gas supply line is located, a variety of options are possible for routing the gas
connection lines. First, install the 3/8" fitting to the heater regulator using sealant. Direct the attachment
either left or right toward the gas supply line.
NOTICE: Most building codes do not permit concealed gas connections. Check your local building
code before using a flexible gas line for this installation.
2. Install the gas line to the 90 deg. fitting, and attach it to the shutoff valve (see Fig. 12 & 13). Depending on
your connection, it might be necessary to cut and access the hole in the side or bottom of the mantel cabinet.
3. Check all connections for gas leaks.

CHECKING GAS CONNECTIONS
Pressure Testing Gas Supply Piping System
Test Pressures in Excess Of 1/2 PSIG (3.5 kPa):
1. Disconnect the heater, including the main gas valve (control valve) and equipment shutoff valve, from
the gas supply piping system. Pressures greater than 1/2 PSIG will damage the regulator.
2. Cap off the open end of the gas pipe where the equipment shutoff valve was connected.
3. Open the gas supply tank valve or use compressed air to pressurize the supply piping system.
4. Check all joints of the gas supply piping system. Use a mixture of liquid soap and water in the gas joints
to check for leaks—bubbles may indicate a leak.
5. Immediately correct all leaks.
6. Reconnect the heater and equipment shutoff valve to gas supply. Check reconnected fittings or leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa):
1. Close the equipment shutoff valve (see Fig. 14).
2. Open the gas supply tank valve or use compressed air to pressurize the supply piping system.
3. Check all joints from the gas meter to the equipment shutoff valve (see Fig. 15.1 & 15.2).
4. Use a mixture of liquid soap and water in the gas joints to check for leaks—bubbles may indicate a leak.
5. Immediately correct all leaks.
Pressure Testing Heater Gas Connections:
1. Open the equipment shutoff valve (see Fig. 14).
2. Open the gas supply tank valve.
3. Ensure the control knob of the heater is in the OFF position.
4. Check all joints from the equipment shutoff valve to the control
valve (see Fig. 15.1 & 15.2). Use a mixture of liquid soap and water
in the gas joints to check for leaks—bubbles may indicate a leak.
5. Light the heater (see OPERATION, page 21-23). Check all other
internal joints for leaks.
