PREPARING FOR INSTALLATION
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a room or space unless the required volume
of indoor combustion air is provided by the method described in the Nation Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 9 through 11 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
A conned space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw)
of the aggregate input rating of all appliances installed in that space and an unconning space as a
space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate
input rating of all appliances installed in that space. Rooms connecting directly with the space in
which the appliances are installed*, through openings not furnished with doors, are considered a
part of the unconned space.
This heater shall not be installed in a conned space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
* Adjoining rooms are connecting only if there are doorless passageways or ventilation
grills between them.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and venti-
lation. However, in buildings of unusually tight construction, you must provide additional
fresh air.
Unusually tight construction is dened as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder
with a rating of one perm (6x10-11kg per pa-sec-m2) or less with openings gasketed or sealed
and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames,
between sole plates and oors, 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 “Ventilation Air From Outdoors” (page 10). If your home does not meet all of the
three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

PREPARING FOR INSTALLATION
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned 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 × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 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 cu. ft. to determine the maximum BTU/hr the space can support.
_______ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
Example: 2560 cu. ft. (volume of 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 Example:
Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr
Total = ____BTU/hr Total = 56,000 BTU/hr
*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 : 51,200 BTU/hr (maximum the space can support) 56,000 BTU/hr (actual amount of
BTU/hr used)
The space in the above example is a conned 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
unconned space, remove door to adjoining room or add ventilation grills between rooms. See
“Ventilation Air From Inside Building,” page 11.
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 unconned. If the actual BTU/hr
used is less than the maximum BTU/hr the space can support, the space is an unconned space.
You will need no additional fresh air ventilation.

10
PREPARING FOR INSTALLATION
Ventilation Air From Inside Building
This fresh air would come from adjoining
unconned space. When ventilating to an
adjoining unconned space, you must
provide two permanent openings: one
within 12 in. of the wall connecting
the two spaces (see options 1 and 2,
Fig. 4). You can also remove door into
adjoining room (see option 3, Fig. 4).
Follow the National Fuel Gas Code
NFPA 54/ANS Z223.1. Air for Combustion
and Ventilation for required size of
ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or duct. You must provide two
permanent openings: one within 12 in. of
the ceiling and one within 12 in. of the oor.
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/ANS Z223.1. Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated
air entering the attic will activate the power
vent. Rework worksheet, adding the space
of the adjoining unconned space. The
combined spaces must have enough fresh
air to supply all appliances in both spaces.

CONNECTING TO GAS SUPPLY
WARNING: A qualied service technician must connect heater to gas supply. Follow all local
codes.
CAUTION: Never connect heater directly to the gas supply. This heater requires an external
regulator (not supplied). The external regulator between the gas supply and heater must be in-
stalled. Gas supplier provides external regulator for natural gas.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known
as wellhead gas.
The installer must supply an external regulator for liquid propane. The external regulator is
provided by the gas supplier for natural gas. The external regulator will reduce incoming gas pres-
sure. You must reduce incoming gas pressure to between 11 and 14 in. of water column for propane
and between 5 and 11 in. of water column for natural gas. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install external regulator with the vent pointing down as
shown in Fig. 6. Pointing the vent down protects it from freezing rain or sleet.
* Purchase the optional equipment shuto󰀨 valve from your local Home Center store.
INSTALLATION
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 ½ in. diameter
or greater to allow proper volume gas to heater. If pipe is too small, loss of pressure
will occur. Installation must include an equipment shuto󰀨 valve, union, and plugged
1/8-in. NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must
be upstream from heater (See Fig. 10).
IMPORTANT: Install equipment shuto󰀨 valve in an accessible location. The equipment
shuto󰀨 valve is for turning on or shutting o󰀨 the gas to the appliance. 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.
