M40DV-CR/CL Corner Gas Fireplace
Maintenance
General
Have the fireplace installation inspected yearly, including a visual
check of the vent system, the burner and the pilot flame. For con-
venience a 1/8" manifold pressure tap is supplied on the gas valve
for a test gauge connection. See Figure 25.
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 the protective coatings on new metal.
Glass must be cleaned periodically to remove any film (a normal
bi-product of combustion) which may be visible. Film can easily
be removed by removing the door, as shown on page 9. Handle
the door carefully, and clean it with an approved glass cleaner.
One of the most effective products is Kel Kem.
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 by following the steps
described below.
Use a vacuum cleaner or soft bristle brush to keep the control
compartment, burner, and firebox free from dust and lint.
Pilot Burner Adjustment
1.
Locate Pilot Adjustment Screw.
(See figure 25.)
2.
Adjust pilot key to provide properly sized flame.
(See figure 26).
3.
After installing or servicing, leak test with a soap solution with
main burner on. Coat pipe and tubing joints, gasket etc. with soap
solution. Bubbles indicate leaks. Tighten any areas where the
bubbles appear until the bubbling stops completely.
