Orifice Size/Altitude Adjustment
For altitudes above 2,000 feet, the orifice should be de-rated
by 4% for every 1,000 feet to maintain the proper ratio of
gas to air. Improper orifice sizing may result in damage
and unsafe conditions. Changing the orifice should only be
done by a qualified service technician. Contact your Lennox

and 24 for more information).

• Must be vented directly to the outside in accordance with
the latest edition of the National Fuel Gas Code and must
never be attached to a chimney serving a separate solid
fuel burning appliance.
• Uses room air for combustion. It is imperative that provi-
sions for adequate combustion and ventilation air be made.
This appliance is NOT designed to and will not operate in
a negative pressure. Contact your dealer if you suspect
such a situation exists.

Fireplace Requirements
These heaters are designed to be installed into an existing
masonry fireplace (built to UBC 37 standards) or factory
built solid fuel, wood burning fireplace (listed to UL 127
standards) only. All exhaust gases must be vented outside
the structure. Combustion air is drawn from outside the
structure. When installing in a factory built fireplace, the
fireplace grate must be removed and the damper must be
removed or secured open.
If the factory-built fireplace has no gas access hole(s) pro-
vided, an access hole of 1-1/2 inches (38 mm) or less may
be drilled through the lower sides or bottom of the firebox
in a proper workmanship like manner. This access hole must
be plugged with a non-combustible insulation after the gas
supply line has been installed.
The installer must mechanically attach the marking supplied
with the gas fireplace insert to the inside of the firebox of the
fireplace into which the gas fireplace insert is installed.
IMPORTANT: When installing these appliances into a fac-
tory built fireplace or heat-form, the air flow within and
around the fireplace shall not be altered by the installation
of the insert (i.e. DO NOT BLOCK louvers or cooling air
inlet or outlet ports, circulating air chambers in a steel
fireplace liner or metal heat circulator).
