Ventilation from Outdoors

If necessary provide extra fresh air by using ventila- tion grills or ducts. Connect these items directly to the outdoors or spaces open to the outdoors. These include attics* and crawl spaces. Follow the National Fuel Gas Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for Com- bustion and Ventilation for required size of ventilation grills or ducts.

*IMPORTANT: Do not provide openings for inlet or outlet into attic. If attic has a thermostat-controlled power vent, heated air entering the attic will activate the power vent.

IMPORTANT: 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 Fresh Air for Combustion and Ventilation, pages 3 through 5.­

INSTALLATION

NOTICE: This heater is intended for the use as supple- mental heat. Use this heater along with your primary heating system. Do not install this heater as your pri- mary 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 your primary heat source for the duration of the outage.­

WARNING: A qualified service person must install heater. Follow all local codes.­

THIS INSTALLATION REQUIRES:

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

•Piping (check local codes)

•Sealant (resistant to natural gas)

•Equipment shutoff valve*

•Ground joint union

•Test gauge connection*

•Sediment trap

•Tee joint

•Pipe wrench

*A CSA/AGA certified equipment shutoff valve with 1/8” NPT tap is an acceptable alternative to test gauge connection. Purchase a CSA/AGA certified equipment shutoff valve from your dealer.

LOCATING HEATER

This heater is designed to be mounted on the wall. The heater can also be located on a non-combustible floor, away from a wall by using the floor mounting stands in- cluded with the heater. If installed on combustible floor- ing such as carpeting, tile or other combustible material other than wood flooring, the heater must be placed on a wood panel the full width and depth of the appliance.

For convenience and efficiency, install the heater:

•Where there is easy access for operation, inspection, and service

•In the coldest part of the room.

•If planning to use fan, locate heater near an electrical outlet.

CAUTION: If you install the heater in a home garage:­ Heater pilot and burner must be at least 18 inches above floor.­ Locate 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 covering or operating heater where impurities (such as tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) are present in the air may discolor walls.­

WARNING: Never install the heater:­

•In a bathroom; except MHBF6NG

•In a bedroom (IR20NGT, IR30NGT, BF20NGT or BF30NGT)­

•In a recreational vehicle­·.

•Where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the heater.­

•As a fireplace insert­

•In high-traffic areas­

•In windy or drafty areas­

WARNING: Heater must be mounted to maintain the minimum clearances shown in Figure 4. If pos- sible, provide greater clearances from the floor, ceil- ing, and joining walls.­
