feed auger operates to deliver
pellets to the brazier when the
burner is in max flame mode.
Adjusting this time adjusts the
boiler input in max flame, i.e. the
larger the load time, the greater the
input, alternatively the smaller the
load time the lower the input (see
table Section 2.2.1).
Units 000.0 seconds.

• TIME PAUSE MAX: Time between
pellet feed auger operations when
the burner is in max flame mode.
Adjusting this time adjusts the
boiler input in max flame, i.e. the
larger the pause time, the lower
the input, alternatively the smaller
the pause time the higher the input
(see table Section 2.2.1).
• TIME PAUSE MIN: Time between
pellet feed auger operations in min
flame. Adjusting this time adjusts
the boiler input in min flame, i.e.
the larger the pause time, the lower
the input, alternatively the smaller
the pause time the higher the input
(see table Section 2.2.1).

cleaned immediately auger run
time exceeds ‘

Brazier and boiler cleaned at next
burner shut-down after auger
run time exceeds ‘
TIME CLEAN
BRAZ ’ and ‘ TIME CLEAN
BOILER ’ periods.
Default setting:
5-18, 6-26 and 9-36 = 1.
