Orifice Size/Altitude Adjustment
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. Chang-
ing the orifice should only be done by a qualified service
technician. Contact your Lennox Hearth Products dealer for
proper orifice sizes. (see Page 26 for more information).
Smoke Detectors
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.
