SAFETY INFORMATION
WARNING:
Carbon monoxide Poisoning: Early signs of
carbon monoxide poisoning resemble the flu,
with headaches, dizziness, or nausea. If you
have these signs, the heater may not be working properly. Get fresh air at once! Have
heater serviced. Some people are more affected by carbon monoxide than others. These
include pregnant women, people with heart or
lung disease or anemia, those under the influence of alcohol, and those at high altitudes.
Natural and Propane/LP Gas: Natural and
propane/LP gases are fuel gases. Fuel gases
are odorless. An odor-making agent are
added to fuel gases. The odor helps you detect
a fuel gas leak. However, the odor added to
fuel gas can fade. Fuel gas may be present
even though no odor exists.

Depletion Sensing (ODS) safety shutoff system.
The ODS/pilot is a required feature for ventfree room heaters. The ODS/pilot shuts off the
heater if there is not enough fresh air.
Piezo ignition system
This heater has a piezo ignitor. This system
requires no matches, batteries, or other

AIR FOR COMBUSTION AND VENTILATION
Today’s home 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 ensure
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
following ventilation classification:
1. Unusually Tight Contruction
2. Unconfined Space
3. Confined Space
The information on page 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.
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 sole plates and floors, between
wall panels, at penetrations for plumbing,
electrical, and gas lines, and at other
openings.
If your home meets all of three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, page 6
If you home does not meet all of the three criteria above, proceed to Determining Fresh-Air
Flow For Heater Location, page 5
4
WARNING: This heater shall not be installed
in a confined space or unusually tight construction unless provisions are provided for
adequate combustion and ventilation. Read
the following instructions to ensure proper
fresh air for this and other fuel-burning
appliances in your home.
WIR 2 26-06-2003 18:21 Pagina 4
Confined and Unconfined Space
The National Fuel gas Code, ANSI
Z223.1/NFP A 54 defines a confined space as
a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour (4,8 m
3
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
m
3
per kw) of the aggregate input rating of all
apliances 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
grilles between them.
DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION.
Determining if you have a confined or unconfined space.
Use this work sheet 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 grilles
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 20ft. (length) x 16 ft
(width) x 8ft (ceiling height) = 2560 cu. ft.
(volume of space)
If additional ventilation to adjoining room
is supplied with grilles or openings, add
the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to deter-
mine the maximum Btu/Hr the space can
support.
________ (volume of space) x 20= 51.200
(maximum 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 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
* Do not include direct-vent gas appliances. Direct-
vent draws combustion air from the outdoors and
vents to the outdoors.
Example
Gas water heater* 40,000
Btu/Hr
Vent-free heater + 20,000
Btu/Hr
Total = 60,000
Btu/Hr
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 4
B. Vent room directly to outdoors. See ventila-
tion air from outdoors, page 4
C. Install a lower Btu/Hr heater, if lower
Btu/Hr size makes room unconfined.
5
WIR 2 26-06-2003 18:21 Pagina 5
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space
is an unconfined space. Y ou will need no additional fresh air ventilation.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconfined space.
When ventilating to an adjoining unconfined
space, you must provide two permanent openings: one within 12” of the ceiling and one
within 12” of the floor on the wall connecting
the two spaces (see options 1 and 2, figure
??). Follow the National Fuel gas Code, ANSI
Z223.1/NFA 54, section air for combustion
and ventilation for required size of ventilation
grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grilles
or ducts. You must provide two permanent openings: one within 12”of the ceiling and one within
12” of the floor . Connect these items directly to the
outdoors. These spaces include attics and crawl
spaces. Follow the National Fuel gas Code, ANSI
Z223.1/NFA 54, section air for combustion and
ventilation for required size of ventilation grills or
ducts.
IMPORT ANT: Do not provide openings for inlet
or outlet air into attic has a thermostat-controlled power vent. Heated air entering the
attic will activate the power vent.
6
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.

LOCATING HEATER
This heater is designed to be mounted on a wall.
IMPORT ANT: vent-free heaters add moisture to the
air. Although this is beneficial, installing heater in
rooms without enough ventilation air may cause
mildew to form from too much moisture. See air
for Combustion and Ventilation, pages 4 through
6. If high humidity is experienced, a dehumidifier
may be used to help lower the water vapor content in the air.
For convenience and efficiency, install heater
•Where there is easy access for operation,
inspection, and service.
• In coldest part of room.
7
NOTICE: This heater is intended for use as a
supplemental heat. Use this heater along with
your primary heating system. Do not install this
heater as your primary heat source. If you have
a central heating system, you may run system’s
circulating blower while using heater. This will
help circulate the heat throughout the house. In
the event of a power outage, you can use this
heater as you primary heat source.
WARNING: A qualified service person must
install heater. Follow all local codes.
WARNING: maintain the minimum clearances
shown in figure 4 if you can, provide greater
clearances from floor, ceiling, and joining wall.
WARNING: Never install the heater
• in the bathroom
•in a recreational vehicle
• where curtains, furniture, clothing, or other
flammable object are less than 36 inches
CAUTION: if you install the heater in a home
garage
• heater pilot and burner must be at least 18
inches above floor
• place heater where moving vehicle will not
hit it.
CAUTION: This heater creates warm air currents. These currents move heat to wall surfaces
next to heater. Installing heater next to vinyl or
cloth wall coverings or operating heater where
impurities (such as, but not limited to, tobacco
smoke, aromatic candles, cleaning fluids, oil or
kerosene lamps, etc.) in the air exist, may discolor walls or cause odors.

• Hook the appliance and fix it in the lower
part, by using the remaining 2 screws.
CONNECTING TO GAS SUPPLY
IMPORTANT: For natural gas, 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.
For propane/LP gas, the installer must supply
an external regulator. The external regulatr
will 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 the external
regulator with the vent pointing down as
shown in figure 6. Pointing the vent down protects it from freezing rain or sleet.
8
WARNING: This appliance requires a 3/8”
NPT (National Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified 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.
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.
fig. 5
Fig.6 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 volume will occur.
WIR 2 26-06-2003 18:21 Pagina 8
Installation must include equipment shutoff
valve, union, and plugged 1/8” NPT tap.
Locate NPT tap within reach for test gauge
hook up. NTP tap must be upstream from
heater (see fig 7)
IMPORTANT: install an equipment shutoff
valve in 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 NTP
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged heater valves.
Install sediment trap in supply line as shown in
fig. 7. Place 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 incorrectly, heater may not run properly.
IMPORTANT: hold the pressure regulator with
wrench when connecting it to gas piping
and/or fittings. Do not over tighten pipe connection to regulator. The regulator body could
be damaged.
CHECKING GAS CONNECTIONS
1. Disconnect appliance with its appliances
main gas valve (control valve) and equipment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig will
damage heater regulator.
2. Cap off open end of gas pipe where
equipment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas
valve located on or near gas meter for natural gas, or using compressed air.
4. Check all joints of gas supply piping system. Apply a non-corrosive leak detection
fluid to all joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected fittings for leaks.

ODS/PILOT AND BURNER
•Use a vacuum cleaner, pressurized air, or
small, soft bristled brush to clean.
CLEANING BURNER PILOT AIR INLET
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides clean burning flame. Keep these holes
clear of dust, dirt, and lint. Clean these air inlet
holes prior to each heating season. Blocked
air holes will create soot. We reccommend
that you clean the unit every three months during operation and have heater inspected yearly by a qualified service person.
We also reccommend than 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 composition.
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.
1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot for dust and dirt.
3. Blow air through the ports/slots and holes
in the burner.
4. Never insert objects into the pilot tube.
Clean the pilot assembly also. A yellow tip
on the pilot flame indicates dust and dirt in
the pilot assembly (see figure 14). With the
unit off, lightly blow air through the air
inlet. You may blow through a drinking
straw if compressed air is not available.
CABINET
Air passageways
•Use a vacuum cleaner or pressurized air to
clean.
Exterior
• Use a soft cloth dampened with a mild
soap and water mixture.
Wipe the cabinet to remove dust.

CAUTION: you must keep control areas,
burner, and circulating air passageways of
heater clean. Do not close this zone. 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, bedding material, pet hair, etc.
WARNING: Turn off heater and let cool
before cleaning
