MAINTENANCE
Burner
Carry out the necessary inspection and maintenance measures described below in connection with
cleaning of the boiler:
Switch off the burner one hour before commencing maintenance of the boiler.
•
The combustion head does not normally require any specific maintenance, but in
•
connection with ash removal it must inspected and any accumulation of ash remo-
ved, as necessary.
When installing the burner back in place, inspect the hatch seals for possible da-
•
mage.
Every 1 to 2 years
Clean the primary air ring and the primary air tube inside from dust and lumps. Check the
condition and tension of the chain. Adjust and replace all defective parts, as necessary. Lub-
ricate the chain with low-viscosity oil.
In connection with a new fuel delivery, the combustion head must be inspected in or-
der to detect sintering (ash as well as stone- and gravel-like particles stuck together in
the combustion head) in good time. Such particles must absolutely be removed from
the combustion head at short intervals to prevent over-heating of and thus dama-
ge to the primary air ring. Sintering is often caused by impurities in the fuel and the
fuel supplier shall be notified immediately of such problems.
See also paragraph ”Advice
about fuel pellets”.
Note!
Handle ash always carefully, because it may still be glowing. Ash must be kept in a fire-re-
sistant container.
The use of any kind of solid fuel requires usually a little more care than in the case of
oil heating, even if the burning would be automatically controlled, such as in BeQuem
pellet burners.
The need of maintenance may vary considerably. It is therefore advisable to inspect
and clean the burner, boiler and its convection parts already after one week’s operation.
In this way the user gains experience to schedule the maintenance at correct intervals.
These maintenance measures should be carried out at frequent intervals. Close the
inlet of combustion air into the boiler room. Put out the fire using a fire extinguisher.
Make a fire alarm, as necessary.
