CAUTION:
Risk of system damage from leaking
connections.
▶ Support the pipes to the boiler to prevent them from
being under stress.
Do not fit the safety valve until the leak test (
5.3, page 21) has been completed.
The relief valve must be installed in a vertical position.
We recommend installing a dirt filter (optional) in the
boiler return connection to reduce build-up of debris on
the water side.
