Note

Lifting eyes are welded to the top of the boiler for

attaching the lifting gear. Alternatively, use the speci-

fied holes in the boiler floor.

BLifting the combustion chamber module

CLifting the heat exchanger module

Note

If required, base frame D and combustion chamber

module B can be removed to facilitate handling; see

page 10.

When refitting the base support, tighten the four

screws with 70 Nm torque.

!Please note

Risk of crushing and injury.

Secure the combustion chamber module to pre-

vent it from falling.

Siting and levelling the boiler

5800301

3. 2.

Fig. 6

1. Insert adjusting screws F (inside the bag on the

boiler support) into the base rails from the top.

2. Undo the timbers from the boiler base.

Note

Remove transport protectors.

3. Level the boiler using the adjusting screws.

Note

We recommend installing the boiler on adjustable

anti-vibration feet C (see page 6) or anti-vibration

boiler supports D/E (see page 6).

Adjustable anti-vibration feet

Insert adjusting feet into the base rails from below.

Anti-vibration boiler supports

Any unevenness in the floor should be max. 1 mm, to

ensure the spring elements are evenly loaded.

Position the boiler supports underneath the boiler. For

this, locate them centrally underneath the base rails.

When setting the boiler down less than square on, a

boiler support can temporarily be overloaded. This can

be prevented by laying timbers (□ 35 mm) under the

front, centre and back of each boiler support.

Siting and levelling the boiler (cont.)

5800301

Fig. 7

The boiler door can be rehung on the opposite side by

moving bolt A to the r.h. side.

Note

Sealing frame B should press centrally onto boiler

door gasket D when the boiler door is closed. If nec-

essary, align mounting bracket C.

Assembly after dismantling

Note

If required, combustion chamber module A can be

removed from heat exchanger module B to facilitate

handling.

To do this, loosen 4 screws in the combustion chamber

module and lower flange.
