WEEKLY MAINTENANCE
FINES TRAY COVER
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 vacuum
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 cleaning
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 Distribution 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.
