Operating Instructions

A. Appliance Controls
Two controls regulate the performance of the Defian
Flexburn 1975: 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 2.1.
Symbols on the stove are reminders of the correct directions
for using the controls. The words 'Left' and 'Right' in these
directions are facing the stove.

A Single Air Control Regulates Heat Output and Burn Time

The primary air control lever, on the right of the stove,
front view
controls the amount of incoming air for starting, maintaining,
controls
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.
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 unit, Figure 2.2.
!
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.

A Damper Directs Air Flow Within the Stove
Holder
The damper handle on the left side of the stove operates
Leg)
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 down. Smoke
travels through the secondary combustion system where
it can be further burned, before passing up the chimney,
Figure 2.3.
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.
