7 Cleaning and servicing the heating system – Procedure

147

Allow the fire in the heating system to burn out and cool down.

Release the M8 screws (13 mm spanner) and remove the cover (3).

Check the chain tension (1).

✓

If the drive chain has approximately 1 cm play, the tension is
correct.

✓

If the drive chain has more play, it must be tightened.

Loosen the locking screw on the chain tensioner (2).

✓

The chain tensioner can be moved.

Move the chain tensioner (2) downwards until the drive chain
again has sufficient tension.

Secure the chain tensioner (2) in this position.

✓

The drive chain is tightened.

Mount the cladding on the boiler in the reverse sequence.

Deactivate the maintenance function.

✎

See section “Maintenance function” in this chapter.

✓

The check of the drive chain of the ash removal system is
completed.
