General
Have the replace 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 appers 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 ame. For your
convenience a ⁄" 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.
• 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 replace area clear and free of combustible materials, as
well as gasoline and other ammable vapors and liquids.
• Do not use this appliance if any part has been under water. Immediately call
a qualied 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 replace is rst activated, there may be some smoke and a visible lm 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 lm which may be visible.
Film can easily be removed by removing the door, as shown on Page 19.
Handle the door carefully, and clean it with non-abrasive glass cleaners.
One of the most eective products is Kel Kem.
• Silicone seals on inner door during initial ring will "o gas", leaving a visual
deposit of a white substance on combustion chamber walls. This can easily
be removed using normal household products.
• Use a vacuum cleaner or whisk broom to keep the control compartment,
burner, and rebox 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
The DV 42* is equipped with an adjustable burner, allowing you to raise or lower the
ames. To adjust the ames, locate the black knob marked 'Hi-Lo', in the center of
the gas control valve (See Figure 32).
• To raise the ame height, turn the black knob (located behind the lower
trim) counter-clockwise.
• To lower the ame height, turn clockwise.
