K. Frequently Asked Questions

ISSUE SOLUTIONS

Condensation on the glass

Blue fl ames

Odor from fi replace

Film on the glass

Metallic noise

This is a result of gas combustion and temperature variations. As the fi replace warms, this
condensation will disappear.

This is a result of normal operation and the fl ames will begin to yellow as the fi replace is al-
lowed to burn for 20 to 40 minutes.

When fi rst operated, this fi replace may release an odor for the fi rst several hours. This is
caused by the curing of materials from manufacturing. Odor may also be released from fi nish-
ing materials and adhesives used near the fi replace. These circumstances may require ad-
ditional curing related to the installation environment.

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. A non-abrasive cleaner such as gas appliance 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
the sound produced by a furnace or heating duct. This noise does not affect the operation or
longevity of the fi replace.
