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 shaped
piece (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 aper-
ture in such a way which would prevent any penetration
of secondary air underneath the nozzle later on. Take the first 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. Take the sec-
ond nozzle and place it in front of the first one. Take the sealing cords and place them along its sides
and front, between the boiler drum and the second front nozzle. By gently tapping calk them evenly
round its circumference so that they are level with the nozzle. Cover the sealing cord connections and
connections of both the nozzles with a small amount of boiler sealant.
