Automatic boiler for wood pellets
Instructions for installation and operation
4/ Now dismantle the burner from the boiler
- 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 2,
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.
- if automatic ignition is installed on the burner, dismantle both spirals and remove all
impurities from the air box of the burner through the installation apertures.
5/ Now sweep out all ash from the boiler thoroughly
In order to prevent from increased dustiness, we recommend to place the lid of the boiler body on
the boiler for this time.
While cleaning, we may not forget about the placement bars of the extension grate which have to
be perfectly cleaned so that individual parts of the extension grate can be precisely placed on them
back.
6/ Back installation of all parts
should be done in reverse order. Ensure mainly the following in
course of this activity:
- Electric resistance coils have to be placed in such a way so that their heating parts are
at least 5 mm from the wall of the burner. Maximum tightness has to be ensured
between the flange of spirals and the wall of the burner.
- The flange of the burner has to be put precisely so that the packing cord of the flange
fits tightly on the protruding ribs of the body all over the circumference.
- The spiral-chute feeder should be anchored precisely in the axis of the pipe and should not
thus drag against the wall of the pipe (which is one of reasons why smooth operation is blocked).
- The joint has to be treated with a sealing paste before the flange of the drive is installed, which
is an important measure against smoke penetration.
- Individual part of the extension grate have to be placed precisely in their correct order.
- The ceramic reflector has to be placed symmetrically
in the corresponding bed of the burner and
plugged in the stop to the rear side. Individual bearing surfaces (of the burner and reflector)
have to be in mutual contact.
- Turbulators of the draughts of combustion products have to be safely fixed on their holders in
order not be jeopardized by their fall on the extension grate.
- Having the back installation been done completely, check via gradual visual check whether all
parts are installed correctly. Finally, try operation of the spiral-chute feeder. Its operation has
to be calm and without any disturbing noise.
