Lighting Instructions
See pages 32 to 34.
CAUTION!
Fireplace gas control must be in the “OFF” position and pilot
and main burners extinguished when cleaning appliance
with a vacuum.
Doors can get very hot. Handle only when cool.
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 explosion relief flappers and 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.
For your convenience a 1/8" manifold pressure tap is supplied on
the gas valve for a test gauge connection.
• Ensure proper log placement as per this manual.
• Inspection of all optional equipment; fans, thermostats, etc.
• Inspection of glass doors and screen for damage and proper
installation.
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 pressure 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 vapors and liquids.
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 25. 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", 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.
Hi-Lo Burner Adjustment: (SIT Nova 820).

to raise or lower the flames. To adjust the flames, locate the black
knob marked 'Hi-Lo', in the centre of the gas control valve (See
Figure 31).
To raise the flame height, turn the black knob (located behind
the lower control compartment) counter-clockwise.
To lower the flame height, turn clockwise.
