Frequently Asked Questions and Troubleshooting 

A. Frequently Asked Questions

ISSUE

SOLUTIONS

 Condensation on the glass

This is a result of gas combustion and temperature variations. As the 

fi

 replace warms, this conden-

sation will disappear.

 Blue 

fl

 ames

This is a result of normal operation and the 

fl

 ames will begin to yellow as the 

fi

 replace is allowed to 

burn for 20 to 40 minutes.

 Odor from 

fi

 replace

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

 nishing materials 

and adhesives used near the 

fi

 replace. These circumstances may require additional curing related 

to the installation environment.

 Film on the glass

This is a normal result of the curing process of the paint. Glass should be cleaned within 3 to 4 
hours of initial burning. A non-abrasive cleaner such as gas appliance glass cleaner may be nec-
essary. See your dealer.

 Metallic noise

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.

 Rock noise 

There may be some “cracking” noise coming from the 

fi

 replace during the 

fi

 rst few heating and 

cooling cycles.  This noise is associated with settling rock and some minor cracking of larger 
pieces of rock.  This will lessen over time as the glass rock is conditioned to the heating and cool-
ing temperature changes.

 Rocks falling through basepan

It is expected that a few small pieces of rock may fall through the basepan and come to rest on the 

fi

 replace bottom.  This has no affect on 

fi

 replace performance.

 Wall above appliance feels hot to   
 the touch.

No action necessary.  This appliance ships with a non-combustible material attached. Speci

fi

 ca-

tions of the attached non-combustible material are listed in the appliance installation manual.
