Adequate combustion and ventilation air must be pro-
vided. The flow of combustion and ventilation air MUST 
NOT be obstructed.
Provide adequate clearances around the air opening 
into the combustion chamber; and adequate accessibil-
ity clearance for servicing and proper operation. NEVER 
obstruct the front opening of the appliance or cover the 
top and bottom louvres (grilles).
The 6" vent system MUST connect to the appliance and 
terminate out-of-doors in a vertical position and terminate 
with a B-vent cap.

Proposition 65 Warning:

California Health & Safety Code Sec. 25249.6

IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

Remove any plastic from trim parts before turning the 
fireplace “ON”. 
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 your gas fireplace to give off some 
odor the first time it is burned. This is due to the curing 
of the paint and any undetected oil used in the manu-
facturing process.

Please ensure that your room is well ventilated.   
Open all windows.

It is recommended that you burn your fireplace for at 
least ten (10) continuous hours the first time you use it. 
If the optional fan kit has been installed, place the fan 
switch in the “OFF” position during this time.

WARNING: Check with your electronics manufac-
turer before installing a television or other electron-
ic device above this fireplace.
