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.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall

not be installed in a conned 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 fuel-burning appliances in your home.

Today’s homes are built more energy efcient 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 efcient, 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, 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 fuel-burning appliances.

3. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.

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 dehumidier 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.

WARNING: This heater shall

not be installed in a room or space unless the required volume 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 dened as an unconned 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.

INSTALLATION

CONNECTING TO GAS SUPPLY

WARNING: A qualied ser-

vice technician must connect heater to 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 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 pipe of 1/2" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

CAUTION: For natural gas, check your gas line pressure before connecting heater to 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/ LP gas, Never connect heater directly to the gas supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and gas supply. Gas supplier provides external regulator for natural gas. The installer provides the external regulator for propane/LP gas.

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or ttings.

CAUTION: Use pipe joint sealant that is resistant to gas (Propane/LP or Natural Gas).

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

• piping (check local codes)

• sealant (resistant to natural gas and propane/LP gas)

• equipment shutoff valve*

• test gauge connection*

• sediment trap

• tee joint

• pipe wrench

• exible gas hose (check local codes)

* A CSA design-certied equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design certied equipment shutoff valve from your dealer.

INSTALLATION

Typical Inlet Pipe Diameters

Use 3/8" black iron pipe or greater. Installation must include an equipment 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 15).

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 pipe. Excess sealant in pipe could result in clogged heater valves.

The installer must supply an external regulator. The external regulator will reduce incom-

ing 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 external regulator with the vent pointing down as shown in Figure 16. Pointing the vent down protects it from freezing rain or sleet.

Install sediment trap in supply line as shown in Figure 15. 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 sediment trap is not installed or is installed wrong, heater may not run properly.

CARE AND MAINTENANCE

MAINTENANCE OF BLOWER MOTOR

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 ame 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, as well as the fan heater 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 for debris restricting air ow. If the fan does not move freely, the unit must be turned off and the fan replaced immediately in order to prevent further damage to the unit.

TROUBLESHOOTING

WARNING: If you smell gas:

• Shut off 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 re department.

WARNING: Only a qualied service technician should service and repair heater. Make sure that 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 ODS/ pilot unit.

IMPORTANT: Operating heater where impurities in air exist may create odors. Cleaning supplies, paint, paint remover, cigarette smoke, cements 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.

Problem Possible Cause Corrective Action

Using natural gas and pilot will not light.

Pressure Switch

When using natural gas (NG), there is a pressure switch that acts to turn off the gas ow 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/LP). 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 qualied service technician can bypass the pressure switch.

Inlet pressure exceeds

9.5" WC.

Before attempting to bypass the pressure switch, make sure the type of gas being used is correct. Check to make sure the connection tting is in the correct inlet on the regulator. Refer to Connecting to Gas Supply, page 15.

Only a qualied installer should bypass the pressure switch. To bypass the pressure switch locate the set screw on the regulator. Use a small at bladed screw driver to turn the set screw counterclockwise 2 turns. This will bypass the pressure switch function.
