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.
Todayʼs 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 effi cient, 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 are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three fol lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space The information on pages 5 through 7 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 out
side atmosphere have a continuous water vapor retarder with a rating of one perm (6 x 10 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 these three cri teria, you must provide additional fresh air. See Ventilation Air From Outdoors, page 7.
If your home does not meet all of the three
-
criteria above, proceed to Determining Fresh-Air Flow For Heater Location.

1. Determine the volume of the space (length x width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 20 ft. (length) x 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. Multiply the space volume by 20 to determine the maximum Btu/Hr (kw) the space can support.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x 20 =
51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr (kw) of all fuel burning appli ances in the space.

Compare the maximum Btu/Hr (kw) the space can
40,000 (11.7) + 22,000 (6.4) = 62,000 (18.2)
support with the actual amount of Btu/Hr (kw) used.
___________ ___________

Example: 51,200 Btu/Hr (15 kw) (maximum
the space can support)
62,000 Btu/Hr (18.2 kw) (actual
amount of Btu/Hr used)
The space in the above example is a confined space because the actual Btu/Hr (kw) used is more than the maximum Btu/Hr (kw) the space can support. You must provide additional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoin-
ing 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.
B. Vent room directly to the outdoors. See Ventila
tion Air From Outdoors, page 7.

C. Install a lower Btu/Hr (kw) heater, if lower Btu/Hr
(kw) size makes room unconfined.
If the actual Btu/Hr (kw) used is less than the maxi mum Btu/Hr (kw) 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 or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 Section 5.3
or applicable local codes.

CONNECTING TO GAS SUPPLY
WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.
WARNIN G: A q ua li fi ed service person must connect heater to gas supply. Follow all local codes.
WARNING: For natural gas, never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
IMPORTANT: For natural gas, check gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5 inches (2.6 kPa) of water. If gas line pressure is higher, heater regulator damage could occur.
CAUTION: For propane/LP gas, 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.
For propane/LP gas, 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 (2.7 and 3.5 kPa) of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install the external regulator with the vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.
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 volume will occur.
Typical Inlet Pipe Diameter All models - 1/2" or greater
Installation must include equipment 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 11).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.
WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

INSPECTING HEATER

Check pilot flame pattern and burner flame pat­tern often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot flame pattern. Figure 21 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 21
turn heater off (see To Turn Off Gas to Appliance, page 14)
• see Troubleshooting, page 17
Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.
