NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
IMPORTANT: Plated polished brass glass
doors may have a plastic covering over all
brass pieces for protection during shipping
and handling. The plastic covering should be
removed before installation of the glass doors.
Under the plastic covering is a protective
lacquer coating which should not be removed.
In some instances, if it is removed, irrevers-
ible damage to the brass finish could occur.
Refer to the following for specific information
on plated polished brass.
IMPORTANT: The lacquer coating on the pol-
ished brass glass doors and trim pieces can
be damaged or removed causing corrosion
and/or tarnish. Do not remove the protective
lacquer coating from plated polished doors
and trim. To help protect the finish; use a
non-acidic wax and avoid the over-spray of
acidic/alkali based glass cleaners on the
brass pieces. Please understand that the
heat of the fire will cause the protective lac-
quer finish to slightly change to a light caramel
color. Do not be alarmed as this is a normal
occurrence.
COMBUSTION AIR
A proper amount of combustion air is important
for your fireplace. Fireplaces consume large
amounts of oxygen.
It is important to allow an adequate supply of
air. If the fireplace is not equipped with an
outside air kit, it may not obtain sufficient
amounts of combustion air from inside the
house or structure in which it is installed.
Therefore, the fire may draw from an outside air
source and pull air in through the chimney. This
may cause smoke spillage into the room.
Smoke spillage often occurs when a fire is first
started, until the fireplace and the chimney has
had the opportunity to “come up to tempera-
ture” and to begin to function normally. If
smoke spillage problems persist, a window
may be opened just a crack to allow the proper
flow of combustion air to the fireplace.
If your fireplace is equipped with an outside
combustion air kit, keep it open at all times
when fire is burning and close when fire is out
to prevent cold air intrusion.
Care and Cleaning of Your Glass Doors
Never clean the glass when the doors are hot.
Do not use ammonia or ammonia based glass
or household cleaner to clean the glass or the
door frame. An ammonia based cleaner will
damage the finish of the glass door.
Clean the glass doors by wiping with a damp
towel followed by a clean dry towel to remove
streaks.
Remove stubborn stains from the glass with a
mild soap solution and a towel dampened with
clean water. Dry with a clean dry towel.
• The fire must always be confined within the
boundaries of the fuel grate.
• The fireplace screens must always be closed
whenever the fireplace is being used.
• Never slam the glass door since it could cause
the glass to break.
• Do not build excessively large or hot fires —
scorching or discoloring of the plated brass
trim may occur.
• Extreme temperature changes can cause glass
breakage — do not build a hot fire and close the
glass doors if the doors are cold.
• If the tempered glass pane becomes scratched
or chipped, it creates a weakness in the glass
which can cause the glass to break when heated.
Replace the pane of glass by contacting your
nearest dealer.
CAUTION: GLASS AND METAL FRAMES
GET HOT — ALWAYS USE HANDLES TO
OPEN AND CLOSE THE DOORS.
Combustion Air Control
The actuator for combustion air system is
standard on all fireplaces but must not be
operated if the complete system is not in-
stalled. See
Figure 4 and refer to Figure 2
.
On this Lennox Elite Series fireplace, the con-
trol lever has been pre-installed. A cover plate
has been mounted over this control lever only
if the outside air kit has not been attached. The
control lever is located on the left hand or
closed side of the fireplace behind the screen.
To open the air damper, pull the lever all the
way out. To close, push the lever all the way in.
REFRACTORIES
All fireboxes contain a furnace refractory floor,
sides and back. These refractories are rein-
forced with steel, but can be broken by improper
use. Dropping logs on the bottom refractory
and building fires directly against the refracto-
ries can cause premature burnout of these
components. It may easily be repaired or re-
placed at costs far below repair and maintenance
for masonry fireplaces.
