Piping between the combustion chamber and the heat exchanger
Installation
WARNING!
Danger of the heat exchanger tipping over during
lifting.
There is an increased danger of tipping
over when lifting via pallet jack. Possible
injuries and property damage could then
occur.
Adequately secure the heat exchanger against
accidents during transport.
Adjust the height of the heat exchanger with the
levelling feet. The threaded pins of the combustion
chamber must be positioned in the centre of the slots.
Fasten the heat exchanger to the combustion chamber
with M12 nuts and washers. Tighten the nuts evenly
and cross-wise, so the seal is pressed on firmly and
evenly.

chamber
WARNING!
Injuries caused by heavy moving parts
Possible crushing injuries due to the two
heavy heat exchanger covers.
Work carefully around the open heat exchanger
covers so that they do not accidentally fall shut.
Do not lift the whole boiler again
As soon as the combustion chamber has been
screwed together with the heat exchanger, the
boiler may no longer be lifted.
Otherwise forces that are too high would impact the
connecting flange and this would cause damage.
Insulate the junction with the heat exchanger
Insulate the junction from the combustion chamber to
the heat exchanger with the supplied insulation.

Piping between the combustion
chamber and the heat exchanger
Install the piping between the combustion
chamber and the heat exchanger
Install the piping between the combustion chamber
and the heat exchanger. First, install the piping for the
flow on both sides of the boiler. Then install the piping
for the return.
