DAMPER CONTROL

This fi replace is fi tted with a manually controlled
chimney damper. The chimney damper should
be closed when the fi replace is not in use to
prevent cold air from entering the home through
the chimney system.
The damper is controlled through the use of a
control lever located within the fi rebox opening
at the top center just behind the fi rebox lintel
(Figure 2). The control lever snaps into place
at the extreme range of motion, up and back in
the closed position. When pulled forward and
down, the damper is open.

1. The appliance fl ue damper must always
remain open when operating.
2. The grate in the fi rebox should be centered
on or over the bottom hearth so your fi re
can breath properly. Crumble and twist
plenty of newspapers UNDER the grate and
criss-cross some small dry kindling sticks
on top of the paper or on the bottom of the
grate.
3. Build a pyramid of three split logs (split will
start much faster). Arrange the uneven wood
to provide plenty of air space between.
4. When lighting your fi re, a little smoke may
escape – more likely if the chimney is cold.
To correct this, hold a lighted newspaper up
inside the fi rebox near the chimney open-
ing. This will turn around any downdraft
and clear the fl ue of cold air. As your log
fi re burns below, the updraft will improve
as the chimney heats up.
5. Now, light the paper at both sides of the
fi rebox.
6. Close the screens to prevent the escape of
sparks and embers.
7. For indoor installations, close the damper
only when your fi re is completely out and
ashes are cold. Keep closed when fi replace
is not in use to prevent unnecessary loss of
heated or cooled air.

COMBUSTION AIR INLET

This appliance requires the installation of an
air inlet for proper operation when installed
outdoors.
The fi replace draws air into the chimney and
fi rebox chambers through the air inlet to cool
the fi rebox during operation.
It is important to inspect the air inlet and free
it from any obstruction before operating the
fi replace (see Figure 3).
