SAFETY
INFORMATION

WARNINGS

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, 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, and/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 pro­pane/LP gas. The odor helps you detect a
propane/LP gas leak. However, the odor added
to propane/LP gas can fade. Propane/LP 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 use any
accessory not approved for use
with this heater.

Due to high temperatures, the
appliance should be located out
of traffic and away from furniture
and draperies.

Do not place clothing or other
flammable material on or near
the appliance. Never place any
objects on the heater.

Surface of heater becomes very
hot when running heater. Keep
children and adults away from
hot surface to avoid burns or
clothing ignition. Heater will re­main hot for a time after shut­down. Allow surface to cool be­fore touching.

Carefully supervise young chil­dren when they are in the same
room with heater.

Make sure grill guard is in place
before running heater.

Keep the appliance area clear and
free from combustible materials,
gasoline, and other flammable
vapors and liquids.

4. Heater shall not be installed in a bath­room.

5. Always run heater with control knob
at LOW or HIGH locked positions.
Never set control knob between locked
positions. Poor combustion and higher
levels of carbon monoxide may result.

6. This heater needs fresh, outside air ven­tilation to run properly . This heater has
an Oxygen Depletion Sensing (ODS)
safety shutoff system. The ODS shuts
down the heater if not enough fresh air
is available. See Air for Combustion
and Ventilation, pages 4 through 6.

7. Keep all air openings in the front and
bottom of heater clear and free of de­bris. This will insure enough air for
proper combustion.

8. If heater shuts off, do not relight until
you provide fresh, outside air. If heater
keeps shutting off, have it serviced.

9. Do not run heater

• where flammable liquids or vapors

are used or stored

• under dusty conditions

10. Before using furniture polish, wax, car­pet cleaner, or similar products, turn
heater off. If heated, the vapors from
these products may create a white pow­der residue within burner box or on
adjacent walls or furniture.

11. Do not use heater if any part has been
under water. Immediately call a quali­fied service technician to inspect the
room heater and to replace any part of
the control system and any gas control
which has been under water.

12. Turn off heater and let cool before ser ­vicing. Only a qualified service person
should service and repair heater.

13. Operating heater above elevations of
4,500 feet could cause pilot outage.

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 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 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 worksheet 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 18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2304 cu. ft. (volume of space)

2304 cu. ft. (volume of space) ÷ 50 cu. ft. = 46.1 or 46,100 (maximum Btu/Hr the space can support)

Example:

Gas water heater
Vent-free heater +
Total =

46,100 Btu/Hr (maximum the space can support)

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

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

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.

IMPORTANT:

inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.
