See pages 21 and 22.
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 media 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 LP 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 smoke
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.
Both sides of the glass panel must be cleaned after the first fire.
As part of the ‘burn-off’ process, a white film may form on the
inside of the glass during the first few fires. Do not allow the
film to accumulate as it can become very difficult to remove.
Allow the glass to cool then clean both sides of the glass panel.
• Glass must be cleaned as needed to remove any film (which
is a normal by-product of combustion) which may be visible.
Cleaning is done after removing the door, as previously shown.
Handle the door carefully and clean it with non-abrasive glass
cleaners. One of the most effective products is Gas Appliance
Glass Cleaner by Forrest Paint Co.
• During initial firing, the silicone door seals will "off gas" leaving
a 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 firebox free from dust and lint.
• Media may be cleaned periodically with a vacuum to remove
soot or other contaminates.
Hi-Lo Burner Adjustment: (SIT Nova 820).
The DV 38 is equipped with an adjustable burner, allowing
you to raise or lower the flames. To adjust the flames, locate
the black knob marked 'Hi-Lo', in the center of the gas control
valve (See Figure 32).
•
To raise the flame height, turn the black knob (located
behind the lower trim) counter-clockwise.
•
To lower the flame height, turn clockwise.

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.
