Only a qualified installer may clean the inside of the

However, the boiler must be serviced annually in accordance
with the Installation and Service Manual and the relevant
section of the Benchmark Service Record completed in order to
maintain the warranty.
1. The central heating system should be checked regularly.
Proceed as follows:
For Sealed Systems
If the water pressure is lower than 0.7 bar, the water

• Check radiators for leaks and (especially in damp areas) for
rust.

ensure they can still be rotated.
