Boiler cleaning
Burning solid fuels, even if operation is automated, normally calls for a little more care
and maintenance than oil heating. For 12 maintenance has been minimized
as the result of well planned design and a big ash box holding 20 litres.
Ash is removed when necessary. Th
e convection parts of the boiler are to be cleaned
when the fl ue gas temperature has risen by 20-30˚C above the temperature of a newly
swept boiler. An alarm reminding you of cleaning can be programmed on the control
panel.
Switch off the power to the boiler before servicing!
• Switch
off the burner one hour before servicing.
• Remove the sweeping hatch on the top of the boiler and clean the fl ues.
• Remove the fi xing bolts from the burner and loosen the hose and electric
connections.
• Pull out the burner and remove the ash by brushing the walls of the
combustion
chamber
• Empty the ash box.
The burner
- Carry out checks and measures when needed or in connection with boiler cleaning.
When new pellet fuel is used, always check the burn pot for sintered ashes (crust of
ash or gravel and stone-like particles). Such particles must be removed from the burn
pot at very short intervals to prevent the primary ring from getting overheated and
damaged. Sintering is caused by impurities in the pellet fuel and a claim should be sent
to the supplier at once.
ATTENTION! Show a great care when emptying the ash as it might be glowing hot. Ash must be
kept in a
fi
reproof container.
ATTENTION! Pay special attention to the pellets quality when you receive a new delivery or when
you change supplier.
