IMPORTANT SAFETY INFORMATION
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces
approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (.3KW) of gas
input per hour. Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most supplemental heat
applications, the water vapor does not create a problem. In most applications, the water
vapor enhances the low humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not become a problem:
1. Be sure the heater is sized properly for the application, including ample combustion
air and circulation air.
2. Ifhighhumidityisexperienced,adehumidiermaybeusedtohelplowerthewater
vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.
PRODUCING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1. Air
for Combustion and Ventilation. All spaces in homes fall into one of the three following
ventilationclassications:
1. Unusually Tight Construction
2. UnconnedSpace
3. ConnedSpace
The information on pages 7 through 9 will help you classify your space and provide
adequate ventilation.
Conned and Unconned Space
TheNationalFuelGasCode,ANSZ223.1denesaconnedspaceasaspacewhose
volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned 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 × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft. (width)× 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. Divide the space volume by 50 cubic feet to determine the maximum BTU/hr the space
can support.
(volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
3. Add the BTU/hr of all fuel burning appliances in the space.

outdoors and vents to the outdoors.
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 dened as construction where:
walls and ceilings exposed to the outside atmosphere have a continuous water vapor
retarder with a rating of one perm (6×10-11kg per pa-sec-m2) or less with openings
gasketed or sealed and
Weather stripping has been added on openable windows and on doors and
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 of the three criteria above, you must provide additional fresh
air. See “Ventilation Air From Outdoors”. If your home does not meet all of the three
criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

Ventilation Air From Inside Building
This fresh air would come from adjoining un-
conned space. When ventilating to an adjoin-
ing unconned space, you must provide two
permanent openings: one within 12 inches of
the wall connecting the two spaces (see op-
tions 1 and 2, Figure 1). You can also remove
door into adjoining room (see option 3, Figure
2). Follow the National Fuel Gas Code NFPA
54/ANS Z223.1. Air for Combustion and Ven-
tilation for required size of ventilation grills or
ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or duct. You must provide two permanent
openings: one within 12 inches of the
ceiling and one within 12 inches of the oor
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 NFPA 54/ANS Z223.1,.
Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
The space in the above example is a conned 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:
Rework worksheet, adding the space of an adjoining room. If the extra space
provides an unconned space, remove door to adjoining room or add ventilation grills
between rooms. See “Ventilation Air From Inside Building”,page 9.
Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9.
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 unconned space. You will need no additional fresh air ventilation.
NOTE: If the area in which the heater may be operated is smaller than that dened
as an unconned space or if the building is of unusually tight construction, provide
adequate combustion and ventilation air by one of the methods described in the
National Fuel Gas Code, ANS Z223.1/NFPA. Air for combustion and ventilation or
applicable local codes.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is benecial,
installing heater in rooms without enough ventilation air may cause mildew to form
from too much moisture. See Air for Combustion and Ventilation, pages 8 through 10.
CHECK GAS TYPE
Make sure your gas supply is correct for your log set. If supply is not correct, do not install
heater. Call dealer where you purchased heater for proper gas log set.

Log size Side wall Ceiling
18 in., 24 in., 30 in. 16 in. 42 in.
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. Rework worksheet, adding the space of the adjoining unconfined space. The
combined spaces must have enough fresh air to supply all appliances in both spaces.
INSTALLATION
NOTICE: This heater is intended for use as supplemental heat. Use this heater along
with your primary heating system. Do not install this heater as your primary heat
source. If you have a central heating system you may run the system’s circulating
blower while using the heater. This will help circulate the heat throughout the house.
In the event of power outage, you can use this heater as your primary heat source.
WARNING: A qualied technician must install heater. Follow all local codes.
WARNING: Before installing in a solid flue burning firebox, the chimney flue and
firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified
chimney cleaner. Creosote will ignite if highly heated. A dirty chimney ue may create
and distribute soot within the house. Inspect chimney ue for damage.
WARNING: Maintain the minimum clearances. If possible, provide greater clearances
from the oor, ceiling, and adjoining wall than required.
WARNING: Seal any fresh air vents or ash clean-out doors located on the oor or
wall of replace to prevent drafting caused by pilot outage or sooting. Use a heat-
resistant sealant. Do not seal chimney ue damper.
CAUTION: This heater creates warm air currents. These currents move heat to
wall surface next to heater. Installing heater next to vinyl or cloth wall coverings
or operating heater where impurities (such as tobacco smoke, aromatic candles,
cleaning uids, oil or kerosene lamps, etc.) in the air exist may discolor walls.
NOTICE: State or local codes may only allow operation of this appliance in a vented
conguration. Check your state or local codes.

burning replace with a working ue constructed of noncombustible material. You may
use this heater as a vented product. There are three reasons for operating your heater as
a vented model:
1. The replace 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.
If reasons number 1 or 2 above apply to you, you must permanently open chimney ue
damper. You must install the damper clamp accessory (not provided). This will ensure
vented operation (see Figure 9). The damper clamp will keep damper open. Installation
instructions are included with clamp accessory.
See chart below for the minimum permanent ue opening you must provide. Attach
damper clamp so the minimum permanent opening will be maintained at all times.

INSTALLING HEATER BASE ASSEMBLY
CAUTION: Do not remove the metal data plates attached to the heater base assembly.
The data plates contain important warranty information.
WARNING: You must secure this heater to replace oor. If not, heater will move when
you adjust controls. Moving heater may cause a gas leak.
WARNING: If installing in sunken replace, special care is needed. You must raise the
replace oor to allow access to heater control panel. This will insure adequate air ow
and guard against sooting. Raise replace oor with noncombustible material.
CAUTION: Do not pick up heater base assembly by the burner. This could damage
heater. Handle base assembly only by grates.
IMPORTANT: Make sure the heater burners are level. If heater is not level, heater will
not work properly. Avoid damage to thermostat bulb. Avoid nicks or sharp bends in ther-
mostat bulb wire. Keep thermostat bulb in mounting bracket.

CONNECTING TO GAS SUPPLY
WARNING: A qualied service technician must connect heater to gas supply.
Follow all local codes.
WARNING: This appliance requires 1/2-inch NPT (National Pipe Thread) inlet
connection to the pressure regulator.
WARNING: Never connect heater to private (non-utility) gas wells. This is com-
monly known as well-head gas.
CAUTION: Never connect heater directly to the natural or propane/LP supply.
This heater requires an external regulator (not supplied). Install the external
regulator between the heater and natural or propane/LP supply.
1. Apply pipe joint sealant lightly to tting threads. Connect approved exible gas
hose to gas regulator of heater (see Figure 11).
Figure 10 - Attaching Heater Base to Fireplace Floor
NOTE: Never apply pipe sealant to are tting threads.
IMPORTANT: Hold gas regulator with wrench when connecting exible gas hose.
2. Locate masonry screws in hardware package.
3. Position heater base assembly in replace.
4. Place logs in their proper position on heater base.
5. Center heater base and logs front-to-front and side-to-side in replace.
6. Carefully remove logs without moving heater base.
7. Mark screw locations through holes in mounting brackets (see Figure 11). If install-
ing in a brick-bottom replace, mark screw locations in mortar joint of bricks.
8. Remove heater base from replace.
9. Drill holes at marked locations using 3/16-inch drill bit.
10. Attach base assembly to replace oor using two masonry screws (in hardware
package) (see Figure 10).

A CSA/AGA design-certied equipment shutoff valve
with 1/8-inch NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA/
AGA design-certied equipment shutoff valve from
your dealer.
The installer must supply an external regulator. The
external regulator will reduce incoming gas pressure.
You must reduce incoming gas pressure to minimum
allowable on rating label. If you do not reduce incom-
ing gas pressure, heater regulator damage could
occur. Install external regulator with the vent down as
shown in Figure 12. Pointing the vent down protects it
from freezing rain or sleet.
Installation must include equipment shutoff valve,
union, and plugged 1/8-inch NPT tap. Locate NPT tap
within reach for test gauge hook up. NPT tap must
be upstream from heater (see Figure 13). To prevent
performance problems, Propane/LP tank of less than
100 lb. capacity is not recommended.
IMPORTANT: Install an equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to the
appliance. Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant from go-
ing into pipe. Excess sealant in pipe could result
in clogged heater valves.
CAUTION: Use only a new, black iron or steel
pipe. Internally-tinned copper tubing may be used
in certain areas. Check your local codes. Use
pipe of large enough diameter to allow proper gas
volume to heater. If pipe is too small, undue loss
of pressure will occur.
CAUTION: Use pipe joint sealant that is resistant
to natural gas (NG) or liquid petroleum (LP) gas.
Figure 13 - Gas Connection
We recommend that you install a sediment
trap in the supply line as shown in Figure
13. Place sediment trap where it is within
reach for cleaning and 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 incorrectly,
heater may not run properly.
IMPORTANT: Hold pressure
regulator with wrench when
connecting it to gas piping
and/or ttings.

CAUTION: Two gas line installation at the same time is forbidden.
Heater is pre-set at factory for propane gas, no changes are required for connecting to
propane. Only a qualied installer or service technician can perform gas selection and
connecting to gas supply.
For changing from propane to natural gas supply:
1. Overturn chassis, See Figure 14.
2. For NATURAL GAS, press knob using a at screwdriver with a blade the thickness of
a quarter and turn knob clockwise until the knob locks into the NG position (see
Figure 15). Selection valve must be locked in the NG position. Do not operate heater
between locked positions!
3. Remove hex plug (with wrench provided) from natural gas inlet of regulator and install
into LP inlet of regulator; use thread sealant to assure there are no leaks.
CAUTION: To avoid gas leakage at the inlet of regulator, a qualied installer or service
technician must use hex plug with sealant.
For changing from natural gas supply to propane supply:
1. Overturn chassis, See Figure 14.
2. For propane gas, press in knob using a at screwdriver with a blade the thickness of a
quarter and turn knob counterclockwise until the knob locks into the LP position,
see Figure 16. Selection valve must be locked in the LP position. Do not operate heater
between locked positions.
3. Remove hex plug from liquid propane inlet of regulator and install into NG inlet of
regulator; use thread sealant to assure there are no leaks.
