IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, oper­ate, or service this heater. Im­proper use of this heater can cause
serious injury or death from burns,
fire, explosion, electrical shock,
and carbon monoxide poisoning.

DANGER: Carbon monoxide

poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of

carbon monoxide poisoning resemble the flu,
with headaches, dizziness, or nausea. If you
have these signs, the heater may not be work­ing properly. Get fresh air at once! Have
heater serviced. Some people are more af­fected by carbon monoxide than others. These
include pregnant women, people with heart or
lung disease or anemia, those under the influ­ence of alcohol, and those at high altitudes.

Propane/LP Gas: Propane/LP gas is odor-

less. An odor-making agent is added to the gas.
The odor helps you detect a gas leak. How­ever, the odor added to the gas can fade. Gas
may be present even though no odor exists.

Make certain you read and understand all warn­ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.

WARNING: Any change to
this heater or its controls can be
dangerous.

WARNING: Do not allow fans
to blow directly into the fireplace.
Avoid any drafts that alter burner
flame patterns. Ceiling fans can
create drafts that alter burner
flame patterns. Altered burner
patterns can cause sooting.

WARNING: Do not use a
blower insert, heat exchanger
insert, or other accessory not ap­proved for use with this heater.

Due to high temperatures, the

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 (6x10
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

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 + 31,500 Btu/Hr
Total = 71,500 Btu/Hr

51,200 Btu/Hr (maximum the space can support)
71,500 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

105190

National Fuel Gas Code, ANS Z223.1, Section 5.3

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 NFPA 54/ANS Z223.1, Section

5.3, Air for Combustion and Ventilation for

required size of ventilation grills or ducts.

WARNING: 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.

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

OWNER’S MANUAL

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: 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 flue 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

heater

• in a bedroom or bathroom un­less installed as a vented ap­pliance, see page 10

• in a recreational vehicle

• where curtains, furniture,
clothing, or other flammable
objects are less than 42 inches
from the front, top, or sides of
the heater

• in high traffic areas

• in windy or drafty areas

CAUTION: This heater cre­ates warm air currents. These
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.

CHECK GAS TYPE

Use only propane/LP gas. If your gas supply
is not propane/LP, do not install heater. Call
dealer where you bought heater for proper
