WEEKLY MAINTENANCE:

Empty Fines Tray
The small Fines Tray in the side of the stoker
should be removed and emptied
To remove the Fines Tray, first open the door
on the left rear of the stove. Next, loosen the
thumb screws holding the Fines Tray Cover, fig#
20. Next, turn the Cover up 90 degrees and slide
out the Tray as shown. If the Tray has over-
flowed, use a vaccuum cleaner to reach into the
opening and remove the excess material.
Cleaning Glass While Unit Is Burning:
Caution: The glass and door frame will
still be hot, gloves must be worn.
Turn the temperature control to lowest setting
and allow the stove to cool down. Have all clean-
ing supplies ready and close by. Take note at
which # the Feed Adjuster is set, fig 14. Turn
Feed Adjuster knob to "Ash Out". (This is the ash
removal setting.) This setting turns "off" the
Combustion Blower and Feeder Motor but does
not turn "off" the Draft Motor. Now the viewing
door can be opened with minimal exhaust leakage.
Use a safety razor in handle and scrape the inside
of the glass with the blade almost flat to the
surface, Fig 21. The window can now be cleaned
with liquid cleaner and a non synthetic cloth.
CAUTION: HOT GLASS MAY CAUSE
CLEANER TO BOIL. If you take more than 4
minutes, the Distributor Blower will start to cycle
up and down to indicate the Feed Adjuster knob
was left in the "Ash Out" (ash removal setting).
This is not a problem if you remember to return
the Feed Adjuster to its previous setting when
completed.

Soot and Fly Ash

The products of combustion will contain
small particles of fly ash. The fly ash will collect
in the exhaust venting system and restrict the flow
of the flue gases. Incomplete combustion, such as
occurs during startup, shutdown, or incorrect
operation of the room heater, will lead to some
soot formation which will collect in the exhaust
venting system. The exhaust venting system
should be inspected at least once every year to
determine if cleaning is necessary.
