Sudden increase
in the temperature
and the pressure in
the boiler
valves in the system closed
open the valves
expansion vessel is frozen
provide thermal insulation on the
expansion vessel
Water leaking from
the boiler
boiler "sweating, retting",
this is a natural phenomenon
resulting from temperature
differences in the boiler
at each boiler start-up and after each
downtime "warm the boiler up", i.e.,
fire it to the temperature of 70 °C and
maintain this boiler temperature for
several hours
"Rattling, firing" in
the boiler
air in the central heating system
and the boiler, e.g., due to incorrect
filling of the system and the boiler
with water
boiler warming up, i.e., maintaining
the temperature above 70 °C for
longer time until air bubbles are
completely removed from the boiler
bleed the central heating system
with vents
on the radiators
The fan does not
work correctly, The
feeder does not
work correctly
does not start, whines, problems
with start-up, does not reach set
operating values
replace the fan capacitor (see the fan
casing), replace the feeder capacitor
(see the feeder casing)
The moving grate
mechanism does
not work
does not start, a message "Hall
effect sensor" appears
clean the air chamber
of the burner, check the settings of
the grate positioning sensor (Hall
effect sensor), replace the sensor
(see the pellet feeder)
