AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater shall
not be installed in a confined space
or unusually tight construction
unless provisions are provided
for adequate combustion and ventilation air. Read the following instructions to insure 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. Home owners
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, home owners
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, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide adequate fresh air for these appliances. This
will insure proper venting of vented fuelburning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code, NFPA 54/ANS Z223.1, Section 5.3, 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 4 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 10
per pa-sec-m2) or less with openings gasketed or sealed
b. weather stripping has been
added on openable windows and
doors
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 of the three
criteria above, you must provide additional fresh air. See
From Outdoors
If your home does not meet all of the
three criteria above, proceed to
mining Fresh-Air Flow for Heater Location,

Confined and Unconfined Space
The National Fuel Gas Code, ANS Z223.1
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.
This heater shall not be installed in a confined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
* 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
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:
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)
Example:
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
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.
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:
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 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.
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)
Example:
Gas water heater 40,000 Btu/Hr
Vent-free heater + 33,000 Btu/Hr
Total = 73,000 Btu/Hr
51,200 Btu/Hr (maximum the space can support)
73,000 Btu/Hr (actual amount of Btu/Hr used)
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
the methods described in the
105073
National Fuel Gas Code, ANS Z223.1, Section 5.3

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
system’s circulating blower while
using heater. This will help circulate the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
WARNING: A qualified service person must install heater.
Follow all local codes.
NOTICE: State or local codes may
only allow operation of this appliance in a vented configuration.
Check your state or local codes.
WARNING: Make sure the selector switch is in the OFF position before installing heater.
WARNING: Before installing
in a solid fuel burning fireplace,
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 may create and distribute soot within the house. Inspect
chimney flue for damage. If damaged, operate heater with flue
damper closed.
WARNING: Seal any fresh air
vents or ash clean-out doors located on floor or wall of fireplace.
If not, drafting may cause pilot
outage or sooting. Use a heatresistant sealant. Do not seal
chimney flue damper.
WARNING: Never install the

currents move heat to wall surfaces next to heater. Installing
heater next to vinyl or cloth wall
coverings or operating heater
where impurities (such as tobacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls.
IMPORTANT:
Vent-free heaters add moisture to the air. Although this is beneficial,
installing heater in rooms without enough
ventilation air may cause mildew to form
from too much moisture. See Air for Com-
bustion and Ventilation, pages 4 through 6.

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.
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 clear-
ance 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 above apply to you,
you must permanently open chimney flue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
24). This will insure vented operation (see
Figure 10). The damper clamp will keep
damper open. Installation instructions are
included with clamp accessory.
See chart below for minimum permanent
flue opening you must provide. Attach
damper clamp so the minimum permanent
flue opening will be maintained at all times.
Area of Various Standard Round Flues

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 fireplace floor. If
not, heater will move when you
adjust controls. Moving heater
may cause a gas leak.
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 insure adequate air flow and guard
against sooting. 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:
ers are level. If heater is not level, heater will
not work properly.
Make sure the heater burn-

CONNECTING TO GAS
SUPPLY
WARNING: This appliance requires a 1/2" 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
heater 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.
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
inches 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.
WARNING: Never connect
heater 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
pressure 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 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 going into pipe. Excess sealant in pipe
could result in clogged heater valves.
CAUTION: 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.
CAUTION: Avoid damage to
gas control. Hold gas control with
wrench when connecting it to gas
piping and/or fittings.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator (supplied by installer,
see Figure 13)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* An CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection.

CLEANING AND
MAINTENANCE
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,
bedding material, pet hair, etc.
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. You can use a vacuum
cleaner in the blow position. 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.
1. Shut off the unit, including the pilot.
Allow the unit to cool for at least thirty
minutes.
2. Inspect burners, pilot, and primary air
inlet holes on injector holder for dust
and dirt (see Figure 30).
3. Blow air through the ports/slots and
holes in the burners.
4. Check the injector holder located at the
end of the burner tube again. Remove
any large particles of dust, dirt, lint, or
pet hair with a soft cloth or vacuum
cleaner nozzle.
5. Blow air into the primary air holes on
the injector holder.
6. In case any large clumps of dust have
now been pushed into the burner repeat
steps 3 and 4.
Clean the pilot assembly also. A yellow tip
on the pilot flame indicates dust and dirt in
the pilot assembly. There is a small pilot air
inlet hole about two inches from where the
pilot flame comes out of the pilot assembly
(see Figure 31). With the unit off, lightly
blow air through the air inlet hole. You may
blow through a drinking straw if compressed
air is not available.

CLEANING BURNERS
INJECTOR 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.
