IMPORTANT SAFETY INFORMATION

Continued from page 3

16.Keep room area clear and free from combustible materi- als, gasoline and other flammable vapors and liquids.

17.Unvented gas heaters are a supplemental zone heater. They are not intended to be the primary heating appli- ance.

18.Unvented gas heaters emit moisture into the living area. In most homes of average construction, this does not pose a problem. In houses of extremely tight con- struction, additional mechanical ventilation is recom- mended.

19.During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance; possibly causing headaches or eye or lung irritation. This is a normal and temporary occurrence.

The initial break-in operation should last two to three hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in period will be slight and will disappear with continued use.

20.Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations above 2,000 feet, input ratings should be reduced 4 percent for each 1,000 feet above sea level. Refer to the National Fuel Gas Code.

21.The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

22.The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

23.Do not use this room heater if any part has been under water. Immediately call a qualified service technician to inspect the room heater and to replace any part of the control system and any gas control which has been under water.

24.Never burn solid fuels in a fireplace where a unvented room heater is installed.

25.Always have a fireplace screen in place when the appli- ance is in operation and, unless other provisions for combustion air are provided, the screen must have an opening(s) for induction of combustion air.
