For altitudes above 2,000 feet (In Canada 4,500 FT/1370 M),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 quali-
fied service technician. Contact your Lennox Hearth Products dealer for

ORIFICE SIZE/ALTITUDE ADJUSTMENT
NEW YORK CITY, NEW YORK (MEA)
Since there are always several potential sources of fire in any home, we
recommend installing smoke detectors. If possible, install the smoke
detector in a hallway adjacent to the room (to reduce the possibility of
occasional false activation from the heat produced by the appliance). If
your local code requires a smoke detector be installed within the same
room, you must follow the requirements of your local code. Check with
your local building department for requirements in your area.
