FRESH 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 exerpts 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 Contruction
2. Unconfined Space
3. Confined Space.
The information on pages 4 through 6 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.
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.
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 (6x10-11 kg
per pa-sec-m2) or 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 the three
criteria above, you must provide additional fresh air. See Ventilation Air
From Outdoors, page 6.
If your home does not meet all of the
three criteria above, proceed to page 5.

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: 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.
3.
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: 2560 cu. ft. (volume of
space) ÷ 50 cu. ft. = 51.2 or 51,200
(maximum Btu/Hr the space can support)
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
+ 20,000 Btu/Hr
Total
= 60,000 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)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 6.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 6.
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 TO
GAS SUPPLY
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.
NOTICE: A qualified service person must connect heater to gas
supply. Follow all local codes.
WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as well-head gas.
Typical Inlet Pipe Diameters
20,000 Btu/Hr
IMPORTANT: Check gas line pressure before connecting heater to gas line. Gas line
pressure must be no greater than 14 inches
of water. If gas line pressure is higher,
heater regulator damage could occur.
3/8" 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).
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. 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.
IMPORTANT: Hold pressure regulator
with wrench when connecting it to gas piping and/or fittings.

• Do not touch any electric switch;
do not use any phone in your building.
• Immediately call your gas supplier
from a neighbor’s phone. Follow
the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
C. Use only your hand to push in or turn
the gas control knob. Never use tools.
If the knob will not push in or turn
by hand, don’t try to repair it, call a
qualified service technician or gas
supplier. Force or attempted repair
may result in a fire or explosion.
D. Do not use this appliance if any part
has been under water. Immediately
call a qualified service technician to
inspect the appliance and to replace
any part of the control system and
any gas control which has been under water.

BURNER
Continued
Check pilot flame pattern and burner flame
pattern often.
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.

Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob.
Replace front panel.

PILOT FLAME PATTERN
Figure 18 shows a correct pilot flame pattern. Figure 19 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.
Figure 20 shows a correct burner flame
pattern. Figure 21 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.
WARNING: 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
