Combination of all the above.
5. #6 status blink: A 6 blink control board status
indication is caused by poor or incomplete com-
bustion. The Advance Automatic Ignition circuit
board has the ability to track the combustion through
feed settings and ESP temperatures. When the
control board has calculated poor or incomplete
combustion it will shut down the unit as a safety
feature. (Poor or incomplete combustion is a
contributer of creasote which may cause a chim-
ney fire)
A 6 blink status may be caused by several things:
1. Blocked or partially blocked flue.
2. Blocked or partially blocked inlet air.
a. backdraft damper on the inlet pipe may be
stuck closed.
b. if outside air is installed the inlet cover may be
Cleaning Burn Pot
Whenever your stove is not burning, take the op-
portunity to scrape the burn pot to remove carbon
buildup. A vacuum cleaner is handy to remove the resi-
due. Be sure the stove is cold if you use a vacuum.
Carbon buildup can be scraped loose with the fire
burning using the special tool provided with your stove.
Scrape the floor and sides of the burn pot. The carbon
will be pushed out by the incoming fuel. Always wear
gloves to do this.
Removing Ashes
Turn the Temp Dial to number 1 approximately 30
minutes before removing ashes. This will result in a
cooler stove and ash pan.
Maximum Feed Adjuster settings are not needed
in most cases. Operating in the normal range

is
recommended when maximum heat output is not re-
quired. The ESP probe prevents the stove from being
over-fired.
Keep the stove free of dust and dirt.
