Maintenance
General
■
Have the fireplace and installation inspected yearly. The
inspection must include, but is not limited to, the following:
• A visual check of the entire vent system and termination.
• An inspection of the door gaskets to ensure a proper seal.
• An inspection of the burner, vent run, and primary air
openings.
• An inspection of the gas valve, gas components, and pilot
flame.
Cleaning
When the fireplace is first activated, there may be some smoking and
a visible film may be left on the glass. This is a normal condition, and
is the result of burning of protective coatings on new metal.
■ Glass must be cleaned periodically to remove any film (which
is a normal by-product of combustion) which may be visible.
Film can easily be removed by removing the door, as shown in
section. Handle the door carefully, and clean it with non-abrasive,
non-ammonia based glass cleaners. One of the most effective
products is Kel-Kem.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
Do not use ammonia based or abrasive cleaners on the glass, they will permanently
etch the surface. Use an approved gas fireplace glass cleaner such as Kel-Kem or
White off.
