Outside Air; Clear Space Near The Fireplace; Flue Damper; Firescreen - Heatilator A36R Owner's Manual

B. Outside Air
A source of air (oxygen) is required in order for combustion
to take place. Whatever air is consumed by the fi re must be
replaced through cracks around windows, under doors, etc.
Most newly constructed houses or existing homes fi tted with
tightly sealed doors and windows are relatively air tight. In
this case, an outside air source must be made available to
feed combustion air from outside the home.
An outside air control handle allows you control of the out-
side air inlet if your fi replace is equipped with this option.
Use of outside air for combustion is highly recommended to
conserve heated air within the structure and to provide make
up air to keep the fi replace venting properly.
This fi replace will operate correctly only if adequate ventila-
tion is provided to allow proper draft to the fi replace sys-
tem.
See Figure 9.1 for location and operation.
CAUTION
Outside air control handle is HOT. Adjust before lighting
fi re.
C. Clear Space Near the Fireplace
Combustible materials must not be stored on the hearth ex-
tension. Room furnishings such as drapes, curtains, chairs
or other combustibles must be at least 4 ft (1.22 m) from the
open front of the fi replace.
D. Flue Damper
The fl ue damper must be in full open position, and is oper-
ated by moving the handle up toward the top of the fi replace.
Before lighting the fi re, verify this by looking up from the in-
side of the fi replace. Always operate this fi replace with the
damper fully open. Please note: Down drafts, obstructions,
damaged or poor (wet) fuels can cause smoke spillage.
See Figure 9.1 for location and operation.

E. Firescreen
A fi rescreen is always provided to control sparks. It must
be closed whenever the fi replace is in use. Glass doors or
fi rescreens must not be used to hold burning material in-
side the fi replace. Only those glass doors specifi cally tested
and listed for use with the specifi c fi replace model should be
used. Screens should be closed when the glass doors are
closed.

F. Glass Doors
Most effi cient fi replace operation using glass doors is with
the doors open. When the doors are open the screen must
