Frequently Asked Questions and Troubleshooting

Frequently Asked Questions

variations. Prior to appliance being turned on, the inside of the glass has cooled below the dew point producing a byproduct of combus- tion: water in the form of condensation. As the fireplace glass warms, the condensation will disappear.
In the summer, the inside of your fireplace contains hot humid air from outdoors. When the air from outdoors contacts glass cooled below the dew point by your air conditioning, moisture in that air will condense.
Blue flames| This is a result of normal operation and the flames will begin to yellow as the fireplace is allowed to burn for 20 to 40 minutes.
Erratic flames| Verify that the glass assembly is correctly installed and that all glass latches are engaged over the tabs on the glass frame.
Vent baffle/flue restrictor may be needed when long vertical vent runs are used. Refer to Installation Manual Replace with Section 4 Vent Diagrams.
Odor from fireplace| When first operated, this fireplace 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 fireplace. 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 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. Contact 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 fireplace.
Is it normal to see the pilot flame burn continually?| In an intermittent pilot ignition system (IPI), the pilot flame should turn off when appliance is turned off. Some optional control systems available with IPI models may allow pilot flame to remain lit.
Power Outages (battery backup)| This appliance can be operated on battery power in the event of a power outage. To access the battery pack, the decorative barrier front, mesh and glass assembly must be removed. Refer to Section 3 for more details.
Wall above appliance feels hot to the touch.| No action necessary. This appliance ships with a non-combustible material attached. Specifications of the attached non-combustible material are listed in the Installer’s Manual for this appliance.
