FRESH 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 fuelburning appliances in your home.
WARNING
Today’s homes are built more energy efcient 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 efcient, your home needs to breathe. Fresh air must enter your home. All fuelburning appliances need fresh air for proper combustion and ventilation.
Exhaust fans, replaces, 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 are 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 classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 9 and 10 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 dened 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 10.
If your home does not meet all of the three criteria above, proceed to “Determining Fresh- Air Flow For Heater Location,”
page 9.
CONFINED AND UNCONFINED SPACE
The National Fuel Gas Code, ANSI Z223.1 denes a conned 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 unconned
space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m 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 unconned space. This heater shall not
be installed in a conned space or unusually tight construction unless provisions are provided for adequate combustion and
ventilation air.
* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.

Page 9
FRESH AIR FOR COMBUSTION AND VENTILATION
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 conned or unconned 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.
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: 2560 cu. ft. (volume of space)¸ 50 cu. ft. = 51.2 x 1000 = 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 replace logs _______________ Btu/Hr
Other gas appliances* + _______________ Btu/Hr
Total = _______________ Btu/Hr
Example:
Gas water heater 30,000 Btu/Hr
Vent-free heater + 30,000 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 out-doors.
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 conned 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 unconned space, remove
door to adjoining room or add ventilation grills between rooms. See “Ventilation Air From Outdoors,” page 10.
B. Vent room directly to the outdoors. See “Ventilation Air From Outdoors,” page 10.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconned.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconned space. You will
need no additional fresh air ventilation.
If the area in which the heater may be operated is smaller than that defined as an
unconfined space or if 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
INSTALLATION
This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection
to the pressure regulator.
WARNING
Never connect heater to private (nonutility) gas wells. This gas is commonly
known as wellhead gas.
WARNING
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
column. 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.
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" or greater diameter to allow
proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.
CAUTION
A qu alified service perso n must
connect heater to gas supply. Follow
all local codes.

OPERATING INSTRUCTIONS
TO TURN OFF GAS TO HEATER
SHUTTING OFF HEATER
1. Turn control knob clockwise to OFF position to completely shut off the heater.
2. If applicable: Turn off all electric power to the heater.
SHUTTING OFF BURNER ONLY (PILOT STAYS LIT)
Turn control knob clockwise to the PILOT position.
THERMOSTAT CONTROL OPERATION
The thermostatic control used on this heater 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 ow to the burner. This increases or decreases the burner ame 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.
MATCH LIGHTING INSTRUCTIONS
1. Open lower access door (see Figure 1, page 6).
2. Follow steps 1 through 6 under Lighting Instructions, page 20.
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.
Now follow step 9 under Lighting Instructions, page 20.
5. Close lower access door. Contact your dealer to relace or repair the piezo ignitor.

CLEANING AND MAINTENANCE
You must keep control areas, burner, and circulating air passageways of heater clean.
Inspect these areas of heater before each use. Have heater inspected yearly by a qualified
service person. Heater may need more frequent cleaning due to excessive lint from
carpeting, pet hair, bedding material, etc.
CAUTION
CLEANING BURNER INJECTOR HOLDER ANDPILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to
mix with the gas. This provides a clean burning ame. Keep
these holes clear of dust, dirt, lint, and pet hair. Clean these
air inlet holes prior to each heating season. Blocked air holes
will create soot. We recommend that you clean the unit every
three months during operation and have heater inspected yearly by a qualied service person.
We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts
we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store, or home center may
carry compressed air in a can. You can use a vacuum cleaner
in the blow position. If using compressed air in a can, please
follow the directions on the can. If you don’t follow directions
on the can, you could damage the pilot assembly.
Turn off heater and let cool before
cleaning.
WARNING
Ports/Slots

1. Shut off the unit, including the pilot. Allow the unit to
cool for at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figure 24).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner
tube again. Remove any large particles of dust, dirt, lint,
or pet hairs with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector
holder.
6. In case any large clumps of dust have now been pushed
into the burner repeat steps 3 and 4.
Clean the pilot assembly also. A yellow tip on the pilot ame
indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot ame
comes out of the pilot assembly (see Figure 25). With the unit off,
lightly blow air through the air inlet hole. You may blow through a
drinking straw if compressed air is not available.
