Installation with anti-vibration boiler supports

To ensure that the spring elements are uniformly loa-
ded, ensure that the installation surface on site is level,
with max. 1 mm in the floor.
1. Lift the combustion chamber module by the lifting
eyes.
2. Arrange the vibration-absorbing boiler supports
centrally under the base rails.
3. A short-term overloading of a boiler support can
arise when setting the boiler down, due to it tilting.
In order to avoid this overloading, distribute square
timbers ( 35 mm) evenly under the base rails
□
between the boiler supports as an installation aid.
