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 temperatures of the Ladera fireplace. Replacement glassshouldbepurchasedfromaLennoxHearth 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.
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. This replacement part is available from your Lennox Hearth Products dealer in the following dimensions:

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.
If possible, you should choose a location where the chimney will pass through the house without cutting floor or roof joists (see fireplace dimensions 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
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 important 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.
