    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 pres-
sures 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 

appliance 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 
prevent the firebox from coming in contact with com-
bustible materials.

It is normal for fireplaces fabricated of steel 
to give off some expansion and/or contraction 
noises during the start up or cool down cycle. 
Similar noises are found with your furnace heat 
exchanger or car engine.

It is not unusual for gas fireplace to give off some 
odor the first time it is burned. This is due to the 
manufacturing process. 

please ensure that your room is well 

ventilated during burn off — open all 

windows.

It is recommended that you burn your fireplace 
for at least ten (10) hours the first time you use it. 
Place the fan switch in the “OFF” position during 
this time.
