L. Frequently Asked Questions
ISSUE
SOLUTIONS
This is a result of gas combustion and temperature variations. As the appliance warms, this
condensation will disappear.
Condensation on the glass
Blue flames
This is a result of normal operation and the flames will begin to yellow as the appliance is al-
lowed to burn for 20 to 40 minutes.
When first operated, this appliance may release an odor for the first several hours. This is caused
by the curing of the paint and the burning off of any oils remaining from manufacturing. Odor may
also be released from finishing materials and adhesives used around the appliance.
Odor from appliance
Film on the glass
This is a normal result of the curing process of the paint and logs. Glass should be cleaned
within 3 to 4 hours of initial burning to remove deposits left by oils from the manufacturing
process. A non-abrasive cleaner such as gas fireplace glass cleaner may be necessary. See
your dealer.
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to
