Second, work phase must be adjusted with noted values. To adjust that, please use following
formula and following changes.
Percentage = (( Adjusted value / Original value ) - 1) x 100
Adjust the Pellet Type from M8-3 Pellet Type menu. Pressing P1 or P2 will modify the pellet
loading percentage up to a maximum value of +9 and down to a minimum value of -9. Each
step increases or decreases it by 3% of the total period of the feed screw with respect to the
default period (Pellet Type=0).
For example:
Noted parameters are:
Original value = 50
Adjusted value = 41
Calculations:
Percentage = ((41 / 50) - 1) x 100 = (0,82 – 1) x 100 = - 18 %
Pellet Type = -18 / 3 = -6
Set Pellet Type to -6
Chimney Type Optimization:
This optimization has 2 steps:
First, ignition fan speed must be optimized. Since the problem is pellet level is increasing on
the burning pot, fan speed must be increased before work phase. From M8-1 Settings
Factory menu you can increase Pr16 and Pr17 parameters to adjust fan speed on needed
functioning stages. Please note the original and the adjusted parameters.
Second, use the same logic of the percentage formula to adjust the M8-4 Chimney Type
parameter.
Adding Cleaning Phases on Work Phase
After optimizations are made, adding initial cleaning phases will help stove to work for a
longer time without daily cleaning needed. To activate the initial cleaning set the following
parameters from M8-1 Settings Factory menu.
Pr03 = 10
Pr08 = 2700
Pr09 = (Changing according to stove output, set it same as Pr06)
Pr12 = 30
