W ARNING
COMBUSTION
AND
VENTILATION
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 fuel-burning 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 5 through 8 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 (6x10
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
If your home does not meet all of the three criteria above, proceed to page 6.

and
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. ** Cubic feet equals length x width x height of room.

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)
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =
2560 cu. ft. (volume of space)
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:
2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum
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
Gas water heater 40,000 Btu/Hr Vent-free heater + 20,000 Btu/Hr Total = 60,000 Btu/Hr
51,200 Btu/Hr (maximum 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 Ventilation Air From Inside Building, page 7. B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8. 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.

CONNECTING
NOTICE
TO GAS
SUPPLY
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
13. Pointing the vent down protects it from freezing rain or sleet.

External Regulator
Vent Pointing Down
Figure 13 - 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 large enough diameter 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 Model 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 14, page 15). 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 14, page 15. 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
14
installed wrong, heater may not run properly.

THERMOSTAT CONTROL OPERATION
The thermostatic control used on these models 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.
MANUAL LIGHTING PROCEDURE
1. Remove front panel (see Figure 7, page 11).
2. Follow steps 1 through 5 under Lighting Instructions, pages 17 and 18.
3. With control knob pressed in, strike match. Hold match to pilot until pilot
lights.
4. Keep control knob pressed in for 30 seconds after lighting pilot. After 30
seconds, release control knob.
5. Replace front panel.

BURNER FLAME PATTERN
Figure 21 shows a correct burner flame pattern. Figure 22 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than 1/2 the glass panel height.
W ARNING
If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this page.
NOTICE
Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.
