Burner
45
Settings in the burner menu’s below
are based on the boiler using the
Grant fixed angle pellet feed auger at
45° and an auger motor fixed speed
of 8.1 rpm. Only ENplus A1
(EN14961-2) pellets MUST be used
with the Grant SPIRA boilers. These
pellets must be bark and sand free
AND approved by Grant UK.
BEFORE being used in the Spira
boilers. Failure to use approved
pellets will invalidate the product
warranty.

CAUTION
9.7.1.2 ‘menu 2-4- POWER PELLET’
The parameters stored within this folder
are;
a) TIME LOAD MAX: Time the pellet
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.
Default setting 6-26 = 25
(2.5 seconds).
Default setting 9-36 = 65
(6.5 seconds).
b) 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).
Units 000.0 seconds.
Default setting 6-26 & 9-36 = 0025
(2.5 seconds).
c) 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).
Units 000.0 seconds.
Default setting 6-26 = 140
(14.0 seconds).
Default setting 9-36 = 250
(25 seconds).
9.7.1.3 ‘menu 3-4- CLEAN’
The parameters stored within this folder
are;
a) TIME CLEAN BRAZ: Total pellet
feed auger run time before burner
brazier cleaning operation activates.
(If the burner shuts down
immediately or waits for the next
shut down is determined by
‘FLASH CLEANING’ see 8.3.1.3 d.)
Default setting 6-26 & 9-36 =180
(180 minutes).
b) TIME CLEAN BOILER: Total pellet
feed auger run time before boiler
cleaning operation activates.
Default setting 6-26 & 9-36 =180
(180 minutes).
c) TIME CLEAN PERIOD: Time
period boiler cleaning function is
operational once ‘TIME CLEAN
BOILER’ has elapsed.
Default setting 6-26 & 9-36 =60
(60 seconds).
d) FLASH CLEANING:
Commencement of brazier cleaning.
1 = Interrupt burner firing, shut
down and clean brazier when time
is greater than ‘TIME CLEAN
BRAZ’.
0 = at next burner shut-down, clean
brazier when time is greater than
‘TIME CLEAN BRAZ’.
Default setting 6-26 & 9-36 = 1.
e) HOURS SERVIC: Time lapse
period before the burner screen
displays ‘SERVICE’. This is to
indicate a service is now due.
Default setting 6-26 & 9-36 =

Default setting 6-26 = 36.
Default setting 9-36 = 43.
b) POWER MINIMUM; Burner fan
speed setting when burner in ‘min’
output mode.
Default setting 6-26 = 21.
Default setting 9-36 = 26.
c) POWER LIGHTING: Burner fan
speed setting when burner in
lighting mode.
Default setting 6-26 & 9-36 = 20.
