ORIFICE SIZE/ALTITUDE ADJUSTMENT
COMMONWEALTH OF MASSACHUSETTS REQUIREMENTS
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 qualified service
technician. Contact your Lennox Hearth Products dealer for proper orifice
sizes (see Page 21 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.

CAUTIONS
• Trim panels or surrounds must not seal ventilation openings in the existing fireplace that the
appliance is installed in.
• The fireplace in which this gas insert is to be
installed must be thoroughly cleaned if it has
been used to burn wood or synthetic logs. Have
the chimney and all inside surfaces of the fireplace brushed and vacuumed so that no soot,
embers, or loose combustion deposits can be
drawn into the heat circulation blower and blown
into the living area.
• If any portion of the chimney system shows signs
of structural or mechanical weaknesses, such
as: cracks, leaky joints, corroded or warped
surfaces, the faulty portion must be repaired
or replaced prior to installing this appliance.
• The factory built firebox must accept the insert
without modification other than removing bolted
or screwed together pieces such as baffles /
smoke shelf / deflectors, ash lips, glass door,
screen or door tracks, log grates, refractory or
masonry lining and damper assemblies. Any
fireplace component, which is removed, must be
retained so they can be reinstalled to restore the
fireplace to its original operating condition. The
removal of any part must not alter the integrity
of the outer shell of the pre-engineered fireplace
cabinet in any way. Any parts removed must be
replaceable. If any components are removed
from (or altered) from the existing fireplace,
a Warning Label (see Page 5) must be affixed
inside the fireplace firebox, so that it shall be
visible upon removal of the fireplace insert. Note:
RTV high temperature silicone is an approved
adhesive to affix the label.
