Installing the combustion chamber module

Installation without anti-vibration boiler supports

1. Position a plate, e.g. a flat steel strip, underneath
the adjusting screws to distribute the load evenly.
Fig. 6

Installation with anti-vibration boiler supports

To ensure the spring elements bear an equal load, pro-
vide a level installation area on site, with max. 1 mm
unevenness in the floor.
1. Lift the combustion chamber module by the lifting
eyes.
2. Position the anti-vibration boiler supports centrally
under the base rails.

3. When setting the boiler down less than square on,
a boiler support can temporarily become overloa-
ded.
To prevent such overloading, position timbers
(ø 35 mm) under the base rails, evenly placed
between the boiler supports, to act as installation
aids.
4. Position the combustion chamber module on the
anti-vibration boiler supports.
5. Remove the timbers.
