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, 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.
Natural Gas: Natural gas is odorless. An odor-making agent is added to natural
gas. The odor helps you detect a natural gas leak. However, the odor added to
natural gas can fade. Natural 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.

5. This heater needs fresh, outside air ventilation to run properly. This heater has
an oxygen depletion sensor (ODS) pilot light safety system. The ODS shuts
down the heater if not enough fresh air is available. See Fresh Air for Combus-
tion and Ventilation, pages 8 through 11.
6. Never run heater in small, closed room. Open door into next room to help
ventilate.
7. If heater shuts off, do not relight until you provide fresh, outside air. If heater
keeps shutting off, have it serviced.
8. Do not run heater
• where flammable liquids or vapors are used or stored.
• under dusty conditions.
9. Never place any objects on the heater.
10.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 shut-down. Allow surface to cool before touching.
11.Carefully supervise young children when they are in same room with heater.
12.Make sure screen is in place before running heater.
13.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

FRESH AIR
WARNING
FOR
COMBUSTION
AND
VENTILATION
This heater must have fresh air for proper operation. If not, poor
fuel combustion could result. 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 fuel-burning appliances.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.
The information on pages 8 through 11 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 continu-
ous water vapor retarder with a rating of one perm or less with open-
ings 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
If your home does not meet all of the three criteria above, continue reading.
Ventilation Air From Outdoors
and
, page 11
and
.
Unconfined Space
An unconfined space has a minimum air volume of 50 cubic feet for each 1000
BTU/Hr input rating of all appliances in the space (cubic feet equals length x
width x height of space). Include adjoining rooms only if there are doorless
passageways or ventilation grills between the rooms.
Confined Space
A confined space has an air volume of less than 50 cubic feet for each 1000
BTU/Hr input rating of all appliances in the space (cubic feet equals length x
width x height of space). Include adjoining rooms only if there are doorless
8
passageways or ventilation grills between the rooms.

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:
BTU/Hr the space can support)
3. Add the BTU/Hr of all fuel burning appliances in the space.
Example:
* 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 adjoining room or add ventilation grills between
rooms. See Ventilation Air From Inside Building, page 10.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 11.
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

THERMOSTAT CONTROL OPERATION
The thermostatic control used on this heater differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat
used on this heater senses the room temperature. The thermostat adjusts the
amount of gas flow to the burner. This increases or decreases the burner flame
height. At times the room may exceed the set temperature. If so, the burner
will shut off. The burner will cycle back on when room temperature drops
below the set temperature.
The control knob can be set to any heat level between HI and LO.
Note:
The thermostat sensing bulb measures the temperature of air near the
heater cabinet. This may not always agree with room temperature (depending
on housing construction, installation location, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own
comfort levels.

not apply to you.
