SAFETY INFORMATION
WARNINGS
WARNING ICON G 001
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, per­sons 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.

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.
103569
Grill Guard
Heat Shield (RP30D) or Glass Panel (CGP20[L])
Heater Cabinet
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 pages 3 through 5 will help you classify your space and provide adequate ventilation.
3
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 page 4.

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 unconfining 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) = 2560 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. = 51.2 or 51,200 (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
Space size 20 ft. (length) x
2560 cu. ft. (volume of
Example:
Gas water heater 40,000 Btu/Hr Vent-free heater + 20,000 Btu/Hr
Total = 60,000 Btu/Hr * Do not include direct-vent gas appli-
ances. 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 can support) 60,000 Btu/Hr (actual amount of
Btu/Hr used)
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 V entila- tion Air From Inside Building.
B. Vent room directly to the outdoors. See
V entilation Air From Outdoors, page 5.
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.
WARNING: If the area in which the heater may be oper­ated is smaller than that defined as an unconfined space, provide adequate combustion and venti­lation air by one of the methods described in the
Gas Code, ANSI Z223.1, 1992, Section 5.3
codes.

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 page 5). 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.

CONNECTING TO GAS SUPPLY
NOTICE: 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
12. Pointing the vent down protects it from freezing rain or sleet.
Propane/LP Supply Tank
External Regulator
Vent Pointing Down
Figure 12 - External Regulator with Vent Pointing Down
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.
Typical Inlet Pipe Diameters
20,000 Btu/Hr models 3/8" or greater 30,000 Btu/Hr models 1/2" or greater
Installation must include a manual 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 13, page 9).
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.
Install sediment trap in supply line as shown in Figure 13, page 9. Locate sediment trap where it is within reach for cleaning. 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.
