Maintenance
Gas Control Valve
General
Have the fireplace installation inspected yearly, including a visual
check of the vent system, the burner and the pilot flame. For your
convenience a 1/8" manifold pressure tap is supplied on the gas
valve for a test gauge connection. See
Figure 17
.
For
Natural Gas
this appliance requires a minimum inlet pressure
of 5.5" W.C. and a manifold pressure of 3.5" W.C.
For
Propane Gas
this appliance requires a minimum inlet pres-
sure of 11" W.C. and a manifold pressure of 10" W.C.
Always keep the fireplace area clear and free of combustible
materials, as well as gasoline and other flammable vapours and
liquids.
Do not use this appliance if
any part has been under water
. Imme-
diately 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 biproduct of combustion) which may be visible. Film
can easily be removed by removing the door, as shown on page
8. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem.
Silicone seals on inner door during initial firing will "off gas", leav-
ing a visual deposit of a white substance on combustion cham-
ber walls. This can easily be removed using normal household
products.
Use a vacuum cleaner or whisk broom to keep the control com-
partment, burner, and firebox free from dust and lint.
Logs may be cleaned periodically with a vacuum to remove soot
or other contaminates.
