If possible, you should choose a location where
the chimney will pass through the house without
cutting floor or roof joists (see fireplace dimen-
sions Page 9).
Usually,noadditionaloorsupportisneeded
for the fireplace. The adequacy of the floor
can be checked by first estimating the weight
of the fireplace system. Weights are given
on Page 23. Note the floor construction and
consult your local building code to determine
if additional support is needed.
The Montecito fireplace may be installed
directly on the floor or on a raised base (for
proper guidelines, refer to “Hearth Extension
Requirements”)andaminimumof6’8”(2m)

When selecting the location, the chimney outlet
position and the direction of the wind are impor-
tant factor affecting the chimney performance.

turbulence, the chimney must:

GLASS CARE
Glass Replacement
The glass used for the Montecito™ fireplace is
ahightemperatureceramicglass(1,400°F/
760° C). If the glass breaks, it must be replaced
with an identical ceramic glass. Tempered
glass or ordinary glass will not withstand the
high temperatures of the Montecito fireplace.
Replacement glass should be purchased from a
Lennox Hearth Products dealer (see “Replace-
mentParts”,Page 23). DO NOT OPERATE THE
UNIT WITH CRACKED OR BROKEN GLASS.
Glass Cleaning
The Montecito fireplace is designed to keep
the glass clean under normal operating condi-
tions. If the Montecito fireplace is operated
continuously with the combustion air controls
closed, the glass will tend to get dirty unless
the fuel, firebox and glass are maintained at
hot temperatures (see “Refueling For Best
Performance”).Tocleantheglass,therearea

will not clean creosote. Do not use abrasives
such as steel pads, steel wool or oven cleaner
as they will scratch the glass.

FIREPLACE INSTALLATION
Locating The Montecito Fireplace
The best location to install your fireplace is
determined by considering the location of
windows, doors, and the traffic flow in the room
where the fireplace is located, allowing space
in front of the unit for the hearth extension and
the mantel, and taking into consideration the
location of the hot air ducts (optional), outside
air kit and chimney.
Gasket Replacement
Remove the door from the unit (see Page 6)
and lay it on a clean unabrasive surface. To
replace the gasket, first remove all of the old
gasket and gasket cement. Make sure that the
surface is totally clean before applying new
cement (a high temperature silicone caulking
rated at 500° F [260° C], is suitable) or adhesion
problems may result. Apply gasket cement to
the gasket channel and install the new gasket.
