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 11. Handle the door carefully, and clean it
with non-abrasive glass cleaners. One of the most effective products is Kel Kem.
■ Use a vacuum cleaner or whisk broom to keep the control compartment,
exhaust area 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.
