MINIMUM FIRE SHUTTER
The thermostat control was calibrated at the factory and is not adjustable. The operation of the heater may
require a change in calibration of the minimum fire air shutter. Calibration adjustments should be made at room
temperature. The minimum fire air shutter is mounted on the door of the thermostat draft damper mounted behind
the front screen on the lower front of the firebox, fig 14. After stove has cooled the cabinet lid may be opened
to make adjustments.
CAUTION: DO NOT OPEN OR CLOSE TOP WHEN
HEATER IS HOT!
1. To open, when stove has cooled grasp the cabinet
top at front (figure 13A) and lift all the way up.
2. Gently lower the top until the top support rod latches
to hold the top in the up position (figure 13B).
3. To close, lift the top until the support rod is un-
latched.
4. Pull the support rod forward as you lower the cabi-
net top.
Adjusting the Minimum Air Shutter:
The minimum air shutter has an infinite number of set-
tings. Several adjustments may be necessary for the unit
to work most effectively for your particular installation.
1. The minimum air shutter may be adjusted to the
closed position in installations where the draft is
“above normal.” Generally, 0.06 w.c. or above would
be considered “above normal.”
2. In installations where the draft is “below normal”,
the minimum air shutter would be adjusted toward
the open position.

2. Add fuel being careful not to overload or over fie
the stove. Never smother the fire when adding coal.
Incomplete combustion of fresh coal will cause gas
accumulation and a mild smokey explosion will oc-
cur. Add fresh kindling if the coal bed has cooled.
3. Do not load fuel to such a height or in such a man-
ner that it creates a hazard when opening the door.
Do not add more than 20 lbs/9kg of coal and never
pile coal above the top of the firebrick.
4. Stir the coal and watch the fire. Be sure the new
coal is burning before you close the doors and turn
the thermostat down.
5. Close feed door and secure tightly. Do not operate
the stove with ash pan removed or ash or feed doors
open except when loading fuel.
6. Adjust the thermostat and flue pipe damper as
described below.
7. At least once every 12 hours of operation, crank
the roller grate system to dump ‘clinkers’ and ash
into the ash pan.
8. Empty ash pan regularly. Do not allow ashes to pile
up higher than the sides of the ash pan. If ashes
build up to the grate, it can warp and burnout will
occur. If allowed to overfill, ashes may spill when
removing the pan.
9. Properly dispose of hot ashes (see Safety
Instructions, item #14 on page 2).
MINIMUM FIRE
The rate of burning at the “LOW” thermostat setting
can be further controlled by adjusting the draft damper
door located behind the cabinet on the front of the
firebox (figure 14).
1. Partially close the shutter to make the fuel burn
longer.
2. Open the shutter, exposing a larger opening, to
reduce the formation of soot (see notes on Chimney
Draft, page 16.)
3. Do Not operate the heater with the minimum fire
shutter completely closed (see below).
