■ Have the fireplace and installation inspected yearly.
The inspection must include, but is not limited to, the

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.
■ 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

door, as shown on Page 22. 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
using normal household products.
■ Use a vacuum cleaner or whisk broom to keep the
control compartment, burner, and firebox free from dust
and lint.
