Burner settings for DxxPX and PXxx boilers follow instruction manual for this boilers.
INFO – If the boiler power is lower than 15 kW, switch off the extraction fan on the boiler
by removing the connector of the extraction fan from the boiler hood. This does not apply
for boilers with burner built in the upper doors and boilers DxxPX, PXxx where the
exhaust fan must always be running with the pellet burner. If necessary, if there is a
limited space in the boiler room, you can shorten the length of the conveyor (worm) or its
leg any time as desired, but the angle of the conveyor should never exceed 45°.
Minimum length of hose between the burner and the conveyor must be bigger than 20 cm.
Maximum hose length should not be more than 1 m.
• Parameter S1 – Allowed number of attempts for ignition with fuel supply… (2).
If parameter S1 is set to 4, the fuel will always be ignited with both the ignition elements at
the same time (Z1 + Z2) in 2 attempts for ignition with fuel supply.
CAUTION - Always after the last attempt for ignition with fuel supply given by parameter
S1, an attempt for ignition without fuel supply will follow to test the equipment. If the fuel
is not ignited after this attempt, the system will be put out of operation and the ALARM
START error message will appear.
