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 door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. Ventilation Air From Outdoors Provide 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, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.

Follow all local codes. 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 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. CHECK GAS TYPE Use only the correct type of gas (natural or propane/LP). If your gas supply is not the correct gas type, do not install heater. Call dealer where you bought heater for proper type heater. INSTALLATION ITEMS Before installing heater, make sure you have the items listed below. • for propane/LP gas, external regulator (supplied by installer) • piping (check local codes) • sealant (resistant to propane/LP gas) • equipment shutoff valve * • ground joint union • sediment trap • tee joint • pipe wrench • for natural gas, test gauge connection* * A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. The optional CSA design-certified equipment shutoff valve can be purchased from your dealer. See Accessories, page 24. LOCATING HEATER WARNING: Maintain the minimum clearances shown in Figure 4. If you can, provide greater clearances from floor, ceiling, and joining wall. You can locate heater on the floor, away from a wall. A wall mounting bracket and floor base stand are included with this heater. Determine which method is best for your application. WARNING: Never install the heater • in a bedroom or bathroom • 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 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. CEILING Minimum Minimum To Top Surface Of Carpeting, Tile Or Other Combustible Material Minimum From Sides Of Heater 36" 2" FLOOR Left Side Right Side 6" Figure 4 - Mounting Clearances As Viewed From Front of Heater 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 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. 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 For convenience and efficiency, install heater • where there is easy access for operation, inspection, and service • in coldest part of room An optional fan kit is available from your dealer.
