IMPORTANT SAFETY INFORMATION

Continued from page 3

14. Caution: Candles, incense, oil lamps, etc. produce

combustion byproducts including soot. Vent-free appliances will not ﬁ lter or clean soot produced by these types of products. In addition, the smoke and/or aromatics (scents) may be reburnt in the vent-free appliance which can produce odors. It is recommended to minimize the use of candles, incense, etc. while the vent-free appliance is in operation.

15. This is an unv ented gas-ﬁ red heater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. See page 7.

16. Keep room area clear and free from combustible materials, gasoline and other ﬂ ammable vapors and liquids.

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

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 construction, addition mechanical ventilation is recommended.

19. During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, ﬁ lms 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. An y 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 heater and its individual shutoff 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 heater must be isolated from the gas supply piping system by closing its individual manual 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 qualiﬁ ed 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. This appliance must not be used with glass doors in the closed position. This can lead to pilot outages and severe sooting outside the ﬁ replace.

25. Never burn solid fuels in a ﬁ replace where a unvented room heater is installed.

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

27. FOR MASSACHUSETTS RESIDENTS ONLY:

Installation of this vented gas log in the Commonwealth

of Massachusetts requires the damper be permanently removed or welded in the full open position. In addition, a naturally vented gas log may not be installed in a bedroom or bathroom in the Commonwealth of Massachusetts.

This appliance may be installed in an after-

market, permanently located, manufactured (mobile) home, where not prohibited by local codes.

This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases.
