Checking the thermal insulation components on the boiler door

Danger
When working with high temperature insulation
materials that contain zirconium or aluminium
silicate ceramic fibres, fibre dust may
develop. This fibre dust can be harmful to
health.
Only trained personnel may adjust or replace
the insulation. Wear suitable protective clothing,
especially breathing equipment and safety gog-
gles.
Inserting the turbulators
!
Please note
Burner adjustments and specific system condi-
tions can cause the turbulators to move forward,
which may result in them being burnt. This can
also lead to damage to the thermal insulation on
the boiler door.
Before insertion, the turbulators must be slightly
bent (see steps).
