Combustion Air - Superior CST-38 Homeowner's Care And Operation Instructions Manual

CAUTION: GLASS AND METAL FRAMES GET
HOT — ALWAYS USE HANDLES TO OPEN AND
CLOSE THE DOORS.
WARNING: CERTAIN MODEL FIRE-
PLACES REQUIRE THAT THE GLASS
DOORS BE CLOSED DURING OPERA-
TION. BE AWARE THAT SAFETY GLASS
IS UNPREDICTABLE WHEN HOT AND
MAY BREAK, EXPELLING HOT GLASS
INTO THE ROOM. ADVISE ALL FAMILY
MEMBERS TO REMAIN WELL AWAY
FROM THE FIREPLACE WHEN OPERAT-
ING WITH DOORS CLOSED TO AVOID
ANY POSSIBLE PERSONAL INJURY.
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 after installation of the fireplace
before its use. Under the plastic covering is a
protective lacquer coating which should not
be removed. In some instances, if it is re-
moved, irreversible damage to the brass finish
could occur. Refer to the following for spe-
cific information on plated polished brass.
Please understand that the heat of the fire will
cause the protective lacquer finish to slightly
change to a light caramel color. Do not be
alarmed as this is a normal occurrence.
IMPORTANT: The lacquer coating on the pol-
ished brass glass doors and trim pieces can
be damaged or removed causing corrosion
and/or tarnish. To help protect the solid
brass; use a non-acidic wax and avoid the
over-spray of acidic/alkali based glass clean-
ers on the brass pieces. If the solid brass
begins to turn black, all the protective coat-
ing should be removed and the metal
re-polished, either by hand or profession-
ally. Subsequently, the finish will not be as
"bright" or lustrous without the protective
coating. Solid polished brass will acquire a
patina over years of use. This is a normal
occurrence and can be polished.

COMBUSTION AIR

A proper amount of combustion air is impor-
tant 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 open at all times when
fire is burning and close when fire is out to
prevent cold air intrusion.
Combustion Air Control
The operation and location of the outside air
control lever varies to some extent on different
fireplace models.
On the CR Series fireplaces, the control lever
that operates the outside combustion air valve
has been pre-installed on your fireplace. A
coverplate has been mounted over this control
lever only if the outside air kit has not been
attached. The control lever is located on the
closed end of the fireplace opening behind the
screen. To open the air damper, turn the lever
handle 1/2 turn counter clockwise (or until
lever can be moved upward), then re-tighten at
desired open position. To close damper, re-
verse procedure ( Figure 5 ).

On the Custom Series fireplaces, the control
lever that operates the outside combustion air
valve is located on one lower side behind the
screen panel. Push the lever all the way in to
open the air valve and pull the lever all the way
out to close the air valve ( Figure 6 ).

The outside air damper should be kept closed
on all fireplaces except when the fireplace is in
operation. If there is no heat present in the
firebox, the air damper should be closed at
night before retiring to prevent intrusion of
outside air into the home.
