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, no additional floor support is needed
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 24
. Next, measure the area occupied by
the fireplace which is normally 36” x 24-1/2”
(914mm x 622mm). Note the floor construc-
tion and consult your local building code to
determine if additional support is needed.
The Ladera fireplace may be installed directly
on the floor or on a raised base (for proper
guidelines, refer to “Hearth Extension Require-
ments”) and a minimum of 6’8” (2 m) measured
from the base of the appliance to the ceiling
is required.
When selecting the location, the chimney outlet
position and the direction of the wind are impor-
tant factor affecting the chimney performance.
To allow a maximum draft and to reduce wind
turbulence, the chimney must:
• Penetrate the highest part of the roof.
• Be installed as far as possible of roof offsets,
trees or any other obstructions that may
cause wind turbulence and back drafts in
the chimney.
• The least amount of offsets (elbows) pos
-
sible.
GLASS CARE
Glass Replacement
The glass used for the Ladera™ fireplace is a
high temperature ceramic glass (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 tem-
peratures of the Ladera fireplace. Replacement
glass should be purchased from a Lennox Hearth
Products dealer (see “Replacement Parts”,
Page 24
). DO NOT OPERATE THE UNIT WITH
CRACKED OR BROKEN GLASS.
Glass Cleaning
The Ladera fireplace is designed to keep the
glass clean under normal operating conditions.
If the Ladera 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”). To
clean the glass, there are a number of specially
designed cleaners. Your authorized Lennox
Hearth Products dealer can recommend a
suitable cleaner which is available in your area.
Regular household glass cleaners will not clean
creosote. Do not use abrasives such as steel
pads, steel wool or oven cleaner as they will
scratch the glass.
DO NOT USE CHEMICAL GLASS CLEANERS
ON PAINTED SURFACES AS IT MAY CAUSE
THE PAINT TO PEEL.
CAUTION : DO NOT ALLOW WINDOW CLEANER
TO GET IN CONTACT WITH DOOR GASKET OR
PAINT ON FACADE OR DOOR. ONCE CLOSED,
CONTACT OF GLASS CLEANER WITH THE
FIREPLACE FACADE CAN PROVOKE PAINT
PEELING OFF.

FIREPLACE INSTALLATION
Locating The Ladera 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 (optional) 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.
