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 a 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 construction, 
additional mechanical ventilation is recommended. 

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 shall have an 
opening(s) for induction of combustion air.

26.  Do not fill spaces around the firebox with insulation or 

other materials. These spaces must be maintained to pre-
vent the firebox from coming in contact with combustible 
materials.
