Please note
Scratches on parts that come into
contact with flue gas can lead to
corrosion.
Never put tools or other objects
into the combustion chamber.
1.
Undo nuts and screws of the boiler
body and remove the combustion
chamber module.
2.
Attach adhesive tape to the joints on
the inside of the combustion chamber
to prevent sealant adhering to these
areas. On the heat exchanger mod-
ule, affix adhesive tape approx. 8 to
10 mm behind the front edge.
3.
Evenly and generously apply the
sealant supplied into the annular
groove on the combustion chamber
module.
4.
Attach the combustion chamber
module to the boiler body by securing
with M 16 x 50 screws and nuts at the
top (torque 60 Nm); the spacers
ensure the specified gap between the
modules is maintained.
5.
Insert the gasket (in the pack sup-
plied) into the joint on the water side
between the boiler sections, and con-
nect the flanges with nuts and bolts.
6.
Secure the combustion chamber
module at the bottom with M 12 x 45
screws and nuts (torque 50 Nm); the
spacers ensure the specified gap
between the modules is maintained.
7.
Remove all protruding sealant inside
the combustion chamber. Check
whether sufficient sealant has been
applied all around to prevent any
gaps appearing in the combustion
chamber.
Danger
Leaks can result in a risk of
poisoning through escaping
gas.
Apply the gasket carefully.
8.
Remove the adhesive tape when the
sealant has dried sufficiently (approx.
four hours).
9.
Position gaskets (in the pack sup-
plied) onto both top flanges and fit the
connection lines on the water side.
Connect flanges with nuts and bolts.

Please note
Tighten the screws on the
flanged joint to ensure the
components are not being
damaged and are functioning
correctly.
