WARNING!
Do not attempt to burn solid wood fuels, vented
gas log sets, or any other combustible in this
unvented firebox. Also, do not install a vent
free gas log set in this firebox if the minimum
clearance and height requirements of the log
set are too large for the firebox.
Continued from page 6
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.
21. 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.
22. The appliance and its main gas valve must be discon
-
nected 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).
23. 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).
24. 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.
25. Never burn solid fuels in a fireplace 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 shall have
an opening(s) for induction of combustion air.
27. 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.
Notice: Illustrations shown in this manual reflect
“typical” installations with nominal dimensions and
are for design and framing reference only. Actual
installations may vary due to individual design
preferences. However, always maintain minimum
clearances to combustible materials and do not
violate any specific installation requirements.
WARNING!
Never connect unit to private (non-utility)
gas wells. This gas is commonly known as
wellhead gas.

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