The Defiant
®
Model 1975-CAT-C Controls
Two controls regulate the performance of your appliance: a
primary air control
supplies oxygen for the fire, and a
damper
directs air flow within the stove to activate and deactivate the
combustion system, Figure 5.1.
Symbols cast into the stove are reminders of the correct
directions for using the controls. The words ‘Left’ and ‘right’
in these directions are
facing the stove
.
Figure 5.1
- The controls are conveniently located and easy to
operate.

The handle may be positioned anywhere between the
two extremes for different heat levels.
Damper Positions
Figure 5.3
- The damper is either open or closed. There are no
intermediate positions.
B. Damper Adjustment
The
damper handle
on the left side of the stove operates
the damper to direct air flow within the stove.
The damper is
open
when the handle points to the
rear
,
enabling smoke to pass directly into the chimney. The damper
must be open when starting or reviving a fire, and whenever
the griddle or doors are opened.
The damper is
closed
when the handle points
forward.
Smoke travels through the secondary combustion system
where it can be further burned, before passing up the
chimney, Figure 5.3.
The damper should always be either fully open or fully
closed. There are no intermediate positions. When
closing the damper, be sure to pull firmly enough to snap
the handle into the locked position.
This wood heater has a manufactured-set minimum low
burn rate that must not be altered. It is against federal
regulations to alter this setting or otherwise operate this
wood heater in a manner inconsistent with operating
instructions in this manual.
WARNING
!
A. Primary Air Control
The
primary air control lever
, on the right side of the stove,
controls the amount of incoming air for starting, maintaining,
and reviving a fire.
Once the air control is manually set, a bi-metallic thermostat
automatically maintains the heat output at a constant level
for a more even heat over the life of the burn.
More air entering the stove makes the fire burn hotter and
faster, while less air prolongs the burn at a lower heat output
level, Figure 5.2.
For the greatest air supply and maximum heat output (but
the shortest burn time), move the lever toward the front of
the stove. For a fire that will last longer with less heat, move
the lever toward the rear of the stove.
