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.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a confined space 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 is excerpts from National Fuel Gas Code. NFPA 54/ANSI 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 page 4 (Determining Air Flow) 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
-11
(6x10 less with openings gasketed or sealed
b.weather stripping has been
added on openable windows and doors
c.caulking or sealants are ap-
plied 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 page 6.
Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ2123.1, 1992 Section 5.3) 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.
* Adjoining rooms are communicating only if there are doorless passageways or ventila­tion grills between them.
DETERMINING 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:
16 ft. (width) x 8 ft. (ceiling height) = 2304 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)
Example:
space) ÷ 50 cu. ft. = 46.1 or 46,100 (maximum Btu/Hr the space can sup­port)
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
Example:
Gas water heater 40,000 Btu/Hr Vent-free heater + 6,000 Btu/Hr Total = 46,000 Btu/Hr

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

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/ANSI 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/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation
grills or ducts.
IMPORTANT:
