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. Make certain you read and understand all warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.

Piezo ignition system
This heater has a piezo ignitor. This system requires no matches, batteries, or other sources to light heater.
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.

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.

WIR 2 26-06-2003 18:21 Pagina 7
INSTALLATION
• Sign in the wall to make the hole “A”.
• Drill the wall by using a 1/4” drill.
• Insert the two plastic expansion anchors supplied in the installation kit, in the holes.
• Insert two of the four screws supplied in the holes letting them stick out from the wall for at least 5 mm (see fig. aside)
• Hook the appliance and label the holes B.
• Remove the appliance and by using the same drill as before, drill the holes. Insert the removing 2 plas­tic anchors.
• 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.
9
WARNING: Use pipe joint sealant that is resist­ant to liquid petroleum (LP) gas.
WARNING: test all gas piping and connections for leaks after installing or servicing . Correct all leaks at once.
WARNING: never use an open flame to check for a leak. Apply a non-corrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: For propane/LP gas, make sure external regulator has been installed between propane/LP supply and heater. See guidelines under connecting to Gas Supply, page 8.
* A CSA design-certified equipment shutoff valve with 1/8” NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design certified shutoff valve from your dealer.

OPERATING HEATER
A. This appliance has a pilot which must be
lighted by hand. When lighting the pilot, follow these instructions exactly.
B. Before lighting smell all around the appli-
ance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS.
• Do not try to light any appliance.
• 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 instruction.
• 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.

The thermostatic control used on this model turn on and off the burner. The thermostat used on this heater senses the room temperature. 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 2 comfort level between HI and LOW. All plaques will turn off and on. 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.
Shutting off burner only (pilot stays lit)
Turn thermostat control knob clockwise
to the PILOT position.
Shutting off heater
Turn thermostat control knob clockwise to the OFF position.
INSPECTING HEATER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure shows a correct pilot flame pattern. Figure 13 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 14.
• turn heater off (see above, to turn off the
gas to appliance )
• see troubleshooting, pages 16 through 18

CLEANING AND MAINTENANCE
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.
14
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
