STARTING FIRES-DO NOT USE AN ACCELLERANT SUCH AS:
gasoline, kerosene, litter fluid, or etc. Put dry coal in hopper, pull down coal to
cover entire grate. Crush several charcoal briquettes into smaller pieces, crumble
newspaper and dig it through coal so that it touches the grate. Lay charcoal on top
of newspaper, turn switch on, when charcoal is red, and place a few handful of
coal on top of the charcoal. If fire moves toward bottom of grate before fire is
established, coal feed can be slowed down by turning rd nut Counter Clock Wise
(CCW) or by flipping feed bolt to a sideward position (part #22 on unit
specification sheet).
After starting coal fire: Allow furnace and chimney to warm up. Insert draft gauge
through pre-drilled hole in upper left portion of fire door. Open air shutter
(located on the bottom of scroll between stoker motor and gear box about ½”).
Then with stoker motor running and feeding coal adjust barometric damper until
draft gauge reads (-.02). If draft is less than a (-.02) with the barometric damper
closed you must close the air shutter (located at bottom of scroll between gear box
and stoker motor. If draft is higher than (-.02) you must adjust barometric draft
regulator. Move the weight on barometric damper left or right to obtain the (-.02).
Recheck until you obtain a (-.20).
SETTING TIMER- The timer comes factory set. Yellow clock wheel makes one
revolution every 30 minutes. Each clip sticking out of the yellow wheel will
cause stoker to run approximately 15 seconds when clip touches switch. Timer
settings will vary depending upon chimney drafts. Normal timing cycle is about
one minute on and 14 minutes off (5 cycle clips side by side). Five clips at 0 and
five clips at 15. If timing cycle needs to be increased, just add 1 or 2 clips to both
groups of clips or if in the case of a chimney having poor draft, clips may be
placed in three (3) groups at the numbers 0- 10- 20.
COAL FEED (red nut):
To increase coal feed and fire size, turn red nut counter clockwise (CW).
To reduce coal feed and fire size, turn red nut counter clockwise (CCW).
Initial coal feed: Advance red nut all the way forward. Then turn it counter
clockwise 11 or 12 turns if burning rice coal, if burning buckwheat coal turn coal
feed, 9 0r 10 turns. When furnace is running for about an hour under full load
grates should have about 2” of dead ash on them before falling into ash pan.
After a fire has been established and all fresh coal that was lying on the grate has
burned, it’s time to set coal feed. When stoker unit is running steady
(approximately 1 ½ hour), fire bed should extend downward to lower portion o
