„ Do not use this appliance if any part has been under water. Immediately
call a qualified service technician to inspect the appliance and to
replace any part of the control system and any gas control which
has been under water.
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 on Page
20. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem or White-off
„ Silicone seals on inner door during initial firing will "off gas", leaving
a visual deposit of a white substance on combustion chamber walls.
This can easily be removed from the chamber walls using normal
household products.
„ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
„ Logs may be cleaned periodically with a vacuum to remove soot or
other contaminates.
