BASE AIR
changes speed of fan in all power levels by same number. It is reasonable to use base
air to compensate different characters of particular heating systems. For example if draught in boiler is
very strong the fan may utilise to work with lower rotations in base air negative value (-2Pa).
Menu
LANGUAGE
enables user to select between 17 languages. Table of languages is in Annex 4.

PARAMETERS
gives overview of burner’s default, min and max settings. The menu
enables fine
tuning of the particular burner. In general it is not neccesary. Short description of parameters is given in
Annex 3.
Regular maintenance
4.7
Pellet burners burning chamber requires regular maintenance. The maintenance period depends on the
quality of the pellets and heating intensity. The average maintenance period is one week. The burning
chamber needs cleaning if ash layer on grate is thicker than 1,5 – 2 cm. If there is more ash on the grate
then it directs flame up directly against the burning chamber and burns a hole into it quite fast. That
makes burners work ineffective. If ash gets under the grate then it closes air channels, grate heats over
and gets deformed (Photo 1). That reduces critically burning quality. As even superior quality pellets
contain 0,3 -0,5 % ash, then the
grate has to be cleaned at least once a week.
Depending on the quality
of the pellets, it might be necessary to clean the burner more frequently. Lower quality pellets contain
more ash and nonburning substantces. See Photo 1 .
Well cleaned burning chamber of burner reduces
fuel consumption and increases substantially its lifetime.
Only high quality pellets e.g. ENPlus-A1 (Premium) can be used in PV20a/30a burners.
