IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

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 from the manufacturing 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)hours the ﬁrst time you use it. If optional fan kit has been installed, place fan in the "OFF" position during this time.
