Automatic boiler for wood pellets

Annual audit

Every boiler of the KP series should undergo annual audit after the end of the main heating season. This audit is

necessary in order to prevent from possible non-standard conditions in the next year of operation of the equipment. If
the annual audit is not performed as per the below mentioned programme, this may be considered by the manufacturer

to be the reason for rejection of guarantee conditions in the second year of use. At the same time, the user gets exposed
to a risk of any failure which may cause loss of operating certainty or large physical damage.

Annual audit - due to demanding activities - has to be entrusted to a trained servicing company which will make record of
the audit in the documentation of the boiler.

We proceed as follows during the annual audit:

Turn off the main switch of the control unit

Disconnect the boiler from network by pulling the mains cord from the wall socket or by turning the socket circuit
off in the switchboard.

As we will also work inside the boiler, let us the boiler 2 - 3 hours to cool down before we start next work.

After the boiler gets cooled down

We will start dismantling of ceramic parts through the burner door - i.e.:

Remove the ceramic shield over the burner door (by gradual moving to the left and

Release it then to the bottom right side from the fixation aperture)

Remove the ceramic reflector by simple pulling forward

Remove all parts of ceramic burning out grate. Lift the back side to a maximum possible hights, front side lower
down and remove the part out.

Now remove all ash build-ups by steel brush from ceramic parts.

Note:

Do not forget that all parts are made of ceramic. Work carefully so you do not damage all parts.

Cleaning the draughts of combustion products

If there is automatic cleaning installed, there just has to remove a dust above exchanger by a vacuum cleaner or
by forfeiture dust through pipes of heat exchanger in to a burning chamber.

Proceed as follows:

Close the burner door so that the boiler does not contaminate the boiler room too much when we will clean the
draughts,

Remove lid of the jacketing,

Dismantle the lid of the boiler body (4 screws) and place it on the floor. When you mount it back later, remove

slightly ash from it and be careful not to damage insulation during this operation.

Now release ash from turbulators and

Vacuum dust from the space above exchanger



Note:

With advantage we use ash separator and regular vacuum cleaner

Dismantling of the burner

Remove the fan from the extension pipe on the flange of the burner,

Dismantle the flanged joint (4 screws) from the drive of the spiral-chute Feeder F2, remove the complete feed

screw and place aside. Check it for wear and tear at the same time.

Dismantle now the whole burner flange (4 screws) and remove the burner. Clean the whole inside surface of the

burner carefully with a wire brush, mainly in the place of the feeder's outlet and also in all places of round and
slotted nozzles. These places are most susceptible to sedimentation of solid products of burning.

Finally, remove all solid waste located inside the air box of the burner. Tilt the burner gradually in order to pour
out all impurities from the burner through the pipe of the fan. Work until the burner is completely cleaned.
