Heatproof shaped piece (nozzle) replacement
Material list:
1. Heatproof shaped piece
2. sealing cord (3 pcs)
3. boiler sealant (white)
Procedure: Remove or break up the old heatproof nozzle
(further referred to as „nozzle"). Thoroughly clean the
nozzle holder, which the nozzle was seated on, from tar
and old sealant. Roll slim strands of boiler sealant. Place
these continuously round the nozzle holder aperture in
such a way which would prevent any penetration of sec-
ondary air underneath the nozzle later on. Take the new
nozzle in your hand, stand in front of the boiler and position the nozzle in such a way that its recess
(cut-out) is positioned in a direction away from you and downwards (the recess is positioned inside the
boiler; a mark on the nozzle - if present – is positioned backwards). The secondary air is brought to
the nozzle from the rear section of the boiler. Place the nozzle on its holder and fully push towards the
rear of boiler. Position it in such a way that free play between nozzle and holder is the same on both
- the left and right side. Shape the sealing cords with a hammer so that their cross-section changes
from square to trapezoid shape. Then spread them along the sides and front of the nozzle and by gently
tapping calk them evenly round its circumference so that they are level with the nozzle. Cover the
sealing cord connections with a small amount of the boiler sealant.
Door sealing cord replacement
Procedure: Use a screwdriver to remove the old sealing cord and to clean the groove in which it was
seated. Lightly shape the cord from a square into a trapeze cross-section using a hammer. Press the
sealing cord along the door circumference (place the narrower base into the groove first) in such a way
to ensure that the cord sticks well in the groove (if necessary use a little hammer). Position the lock's
handle upwards, and with several gentle, careful taps of the door against the boiler, press the cord into
the groove until the door can be closed smoothly. Fine-tune the position of the wheel that engages the
lock's cam. This is the only procedure that can ensure good door seal!
Adjusting the door hinges and locks
The loading door and ash-pan door are firmly connected to the boiler drum by two sets of hinges.
Each hinge consists of a nut, which is welded to the boiler drum, and a screw to which the door is
connected by means of a pin. If you want to adjust the hinge settings, first take off the upper hood
(control panel) and remove both pins. Then remove the door and slightly turn the screw with a right-
