WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

• Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (0.3 KWs) of gas input per hour.
• Unvented room heaters are recommended as supplemental heat (a room) rather than a primary heat source (an entire house).
• In most supplemental heat applications, the water vapor does not create a problem.
• In most applications, the water vapor enhances the low-humidity atmosphere experienced during cold weather.
• The following steps will help ensure that water vapor does not become a problem.

1. Be sure the heater is sized properly for the application, including ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.

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 ensure 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. Homeowners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, homeowners 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.
• WARNING: This heater shall not be installed in a room or space unless the required vol-ume of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.
• 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, the International Fuel Gas Code, or applicable local codes.

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 2). You can also remove the door into the adjoining room (see option 3, Figure 2).
• Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for the required size of ventilation grills or ducts.
• Ventilation Air From Outdoors Provides extra fresh air by using ventilation grills 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 or spaces open to the outdoors. These spaces include attics and crawl spaces.
• Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for the required size of ventilation grills or ducts.
• IMPORTANT: Do not provide openings for inlet or outlet air into the attic if the attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.
• Rework the worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

INSTALLATION

• NOTICE: This heater is intended for use as 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 the system’s circulating blower while using the heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source.
• WARNING: A qualified service person must install a heater. Follow all local codes.
• WARNING: Never install the heater
• in a bedroom or a bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other flammable objects are less than 36″ from the front, top, or sides of the heater
• in high-traffic areas
• in windy or drafty areas
• CAUTION: This heater creates warm air currents. These currents move heat to wall surfaces next to the heater.
• Installing a heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may cause walls to discolor.
• IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heaters in rooms without enough ventilation air may cause mildew to form too much moisture. See Air for Combustion and Ventilation, pages 7 and 8.

CHECK GAS TYPE

• Be sure your gas supply is right for your heat-er. Otherwise, call the dealer where you bought the heater for the proper type of heater.

2. Position the heater to the desired location. Secure the base feet to the floor by using two Phillips head screws (provided) (see Figure 13).

GAS SELECTION

• This appliance is factory preset for propane gas. No changes are required for connecting to propane. Only a qualified installer or service technician can perform gas selection and connect to the gas supply.
• CAUTION: Two gas line installations at the same time are prohibited.
• CAUTION: To avoid gas leakage for the gas not being used at the inlet of the regulator, a qualified installer or service technician must use the supplied cap.
• You will notice a color-coded plunger on the inside of the regulator. This is normal. When the inlet connection fitting is inserted and tightened, this plunger will be pushed back by the fitting making all of the adjustments for the gas being supplied. DO NOT REMOVE THE PLUNGER. The regulator will not work and the warranty will be voided.
• The inlet regulator is color-coded for identification of the correct gas type. Blue is for propane and yellow is for natural gas.

FOR PROPANE GAS INSTALLATION: BLUE

• Apply thread sealant to the threads on a 3/8″ NPT brass connection fitting. While pushing in, rotate the fitting clockwise until the threads engage the regulator.
• After the fitting has been hand-tightened into the regulator use a wrench to complete tightening of the fitting. Install additional fitting to connect to the housing supply.

FOR NATURAL GAS

INSTALLATION: YELLOW

1. Remove the metal cap installed over the NG regulator inlet.
2. Install metal cap over Propane regulator
   • Use only the cap supplied on the regulator. Do not use an off-the-shelf pipe plug.
3. This can damage the plunger. The supplied regulator cap is designed so it will not engage the unused gas type.
4. Apply thread sealant to the threads on the connection fitting. While pushing in, rotate the fitting clockwise until the threads engage the regulator.
   • After the fitting has been hand-tightened into the regulator use a wrench to complete tightening of the fitting. Install additional fitting to connect to the house supply.

• Use only the metal cap. DO NOT use an off-the-shelf 3/8″ NPT pipe plug. This will damage the plungers located inside the regulator.
• DO NOT TRY TO REMOVE THE PLUNGERS FROM INSIDE THE REGULATOR. THE PLUNGER WILL BE PUSHED BACK AS THE FITTING IS INSTALLED.
• REMOVING THE PLUNGERS WILL VOID THE WARRANTY.
• Make sure the type of gas being used is correct. Check to make sure the connection fitting is in the correct inlet on the regulator. Refer to Connecting to Gas Supply
• If you are using natural gas and the pilot will not light, see Troubleshooting

CONNECTING TO GAS SUPPLY

• WARNING: A qualified ser-vice technician must connect the heater to the gas supply. Follow all local codes.
• WARNING: This appliance requires a 3/8″ NPT (National Pipe Thread) inlet connection to the pressure regulator.
• WARNING: For natural gas, Never connect the heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
• WARNING: Do not over-tighten gas connections.
• CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain areas. Check your local codes.
• Use a pipe of 1/2″ diameter or greater to allow proper gas volume to the heater. If the pipe is too small, undue loss of pressure will occur.
• CAUTION: For natural gas, check your gas line pressure before connecting the heater to the gas line. Gas line pressure must be no greater than 9.5″ of water. If gas line pressure is higher, heater regulator damage could occur.
• CAUTION: For propane gas, Never connect the heater directly to the gas supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and the gas supply.
• Gas supplier provides external regulators for natural gas.
• The installer provides the external regulator for propane gas.
• CAUTION: Avoid damage to the regulator. Hold the gas regulator with a wrench when connecting to gas piping and/or fittings.
• CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).

Before installing the heater, make sure you have the items listed below:

• piping (check local codes)
• sealant (resistant to natural gas and propane gas)
• equipment shutoff valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
• flexible gas hose (check local codes)
• 3/8″ NPT brass fitting
• A CSA design-certified equipment shutoff valve with a 1/8″ NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer.

Typical Inlet Pipe Diameters

• Use 3/8″ black iron pipe or greater. Installa-tion must include an equipment shutoff valve, union, and plugged 1/8″ NPT tap. Locate the NPT tap within reach for test gauge hook-up.
• NPT tap must be upstream from the heater (see Figure 16
• IMPORTANT: Install an equipment shutoff valve in an 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 threads. This will prevent excess sealant from going into the pipe. Excess sealant in the pipe could result in clogged heater valves.
• The installer must supply an external regulatory. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11″ and 14″ of water.
• If you do not reduce incoming gas pressure, heater regulator damage could occur. Install an external regulator with the vent pointing down as shown in Figure 17. Pointing the vent down protects it from freezing rain or sleet.
• Install sediment trap in the supply line as shown in Figure 16. Place sediment trap where it is within reach for cleaning. Place 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 the sediment trap is not installed or is installed wrong, a heater may not run properly.

CHECKING GAS CONNECTIONS

• 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 noncorrosive leak detection fluid to all joints. If bubbles form, there is a leak. Correct all leaks at once.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM Test Pressures Above 1/2 PSIG (3.5 kPa)

1. Disconnect the heater with its appliance main gas valve (control valve) and equipment shutoff valve from the gas supply piping sys-tem. Pressures above 1/2 PSIG will damage the heater regulator.
2. Cap off the open end of gas pipe where the equipment shutoff valve was connected.
3. Pressurize the supply piping system by either using compressed air or opening the gas supply valve.
4. Check all joints of the gas supply piping sys-tem. Apply a noncorrosive leak detection fluid to all joints. If bubbles form, there may be a leak.
5. Correct all leaks at once.

THERMOSTAT CONTROL OPERATION

• The thermostatic control used on this model differs from standard thermostats. You set standard thermostats to a specific tempera-ture such as 72° F. The control of this heater establishes a “comfort level”. For the thermostat to operate effectively, the heater should be the main source of heat in the room. Follow the instructions for lighting the heater.
• When the room reaches the desired comfort level, rotate the control knob clockwise slowly until the main burner turns off and the pilot remains on (this position on the knob will change depending on room temperature).
• Turn the knob counter-clockwise slowly until the main burner reignites.
• Note the position of the control knob by the numbers printed on the knob. Leave the knob in this position. As the room temperature increases, the main burner will turn off and the pilot will remain on. When the room temperature cools, the heater’s main burner will come back on. If left at this set point the thermostat will turn the main burner on or off as needed to maintain the room temperature at the desired comfort level.
• Note: The thermostat sensing bulb reacts to the temperature depending on housing construction.

• CAUTION: Label all wires before disconnection when servicing controls. Wiring errors can cause improper and dangerous operations.
• WARNING: Never attempt to service the heater while it is plugged in, operating, or hot. Burns and electrical shock could result. Only a qualified service person should service or repair the heater.
• Verify proper operation after servicing. If any of the original wires as supplied with the appli-ance must be replaced, it must be replaced with a wire of at least a 105º C temperature rating.

INSPECTING BURNERS

• IMPORTANT: Owners should check the pilot flame pattern and burner flame pattern often. Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance) or service.
• WARNING: Only a qualified service person should service and repair the heater. This includes maintenance requiring replacement or alteration of components.

PILOT FLAME PATTERN

• Figure 25 shows a correct pilot flame pattern. Figure 26 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple.
• This will cause the thermocouple to cool, which shuts the heater off.
• If a pilot flame pattern is incorrect, as shown in Figure 26
• turn the heater off (see To Turn Off Gas to Ap-pliance see Troubleshooting.
• WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If the burner flame pattern shows yellow tipping, follow the instructions at the bottom of this page.
• Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.

BURNER FLAME PATTERN

• Figure 27 shows a correct burner flame pattern. Figure 28 shows an incorrect burner flame pattern.
• The incorrect burner flame pattern shows a yellow tipping of the flame. It also shows the flame higher than 1/2 the heat shield height.
• If the burner flame pattern is incorrect as shown in Figure 28:
• turn the heater off (see To Turn Off Gas to Ap-pliance see Troubleshooting.

CARE AND MAINTENANCE

• WARNING: Turn off the heater and let cool before servicing.
• CAUTION: You must keep control areas, burner, and circulating air passageways of the heater clean. Inspect these areas of the heater before each use. Have the heater inspected yearly by qualified service technicians.
• A heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
• WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

MAIN BURNER

• Periodically inspect the main burner with the heater running. Debris or rust can cause blockages. If present, turn off the heater let it cool, and remove the blockage. Blockages will create soot.

BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

• We recommend that you clean the unit every 2,500 hours of operation or every three months. 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 PSl. 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.

1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2. Remove four screws securing the front panel.
3. Pull the front panel forward.
4. Inspect burner and pilot for dust and dirt.
5. Blow air through the ports/slots and holes in the burner.
6. Replace the front panel using screws removed.

ODS/PILOT

• Use a vacuum cleaner, pressurized air, or a small, soft-bristled brush to clean.
• A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about 2″ from where the pilot flame comes out of the pilot assembly (see Figure 29).
• 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.

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.

MAINTENANCE OF BLOWER MOTOR (IF EQUIPPED)

• Always disconnect the appliance from the main power supply and allow it to cool before any servicing operation.
• The motors used on the fan heater and flame blower are pre-lubricated for extended bearing life and require no further lubrication. However, periodic cleaning/vacuuming of the appliance around the air intake and exhaust is recommended.
• For heavy or continuous use, periodic cleaning must be done more frequently. If the heater blows alternating cold and warm air, check the fan for free movement and debris restricting airflow.
• If the fan does not move freely, the unit must be turned off and the fan replaced immediately to prevent further damage to the unit.

TROUBLESHOOTING

WARNING: If you smell gas:

• Shut off the gas supply.
• Do not try to light any appliance.
• Do not touch any electrical 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.
• WARNING: Only a qualified service technician should service and repair the heater. Make sure that the power is turned off before proceeding. Turn off and let cool before servicing.
• CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage the ODS/pilot unit.
• IMPORTANT: Operating a heater where impurities in air exist may create odors. Cleaning supplies, paint, paint remover, cigarette smoke, types of cement and glues, new carpet or textiles, etc., create fumes.
• These fumes may mix with combustion air and create odors.
• Note: All troubleshooting items are listed in order of operation.

Bypass pressure switch. See the instructions below.

Pressure Switch

• When using natural gas, there is a pressure switch that acts to turn off the gas flow to the pilot if the inlet pressure exceeds 9.5″ WC. This is to prevent the operation of the unit on the wrong gas (propane).
• If your natural gas supply exceeds 9.5″ WC the unit will not operate. Either contact your gas supplier to check and adjust the inlet pressure or a qualified service technician can bypass the pressure switch.
• Before attempting to bypass the pressure switch, make sure the type of gas being used is correct. Check to make sure the connection fitting is in the correct inlet on the regulator. Refer to Connecting to Gas Supply.

TROUBLESHOOTING

• Only a qualified installer should bypass the pressure switch. Remove the front panel of the heater.
• Locate the gas regulator. To by-pass the pressure switch locate the set screw on the regulator.
• Use a small flat-bladed screwdriver to turn the set screw counterclockwise 2 turns. This will bypass the pressure switch function.
• The entire gas delivery piping including connections inside the heater should be leak tested by the qualified installer.
• After leak testing the qualified installer should light the appliance. Refer to the correct flame pattern as illustrated.
• All flame patterns should be safely inside the product. If for any reason they are not, stop the use of the appliance and call for repairs.
