DANGER:
Danger to life through explosion of flammable gases!
Work on components in contact with gas must only be carried out by
certified gas fitters.
Observe all local regulations relating to the gas connection.
Seal in the gas connections with an approved sealant.
Install gas isolator [2] in the gas line (GAS). When doing so, secure
the gas line inside the boiler to prevent it from becoming twisted.
Subject to local regulations, install thermally activated shut-off device
(TAE). A gas filter and expansion joint must also be installed in the gas
line according to the local regulations and guidelines.
Connect expansion joint [1] (recommended) to the gas isolator.
Connect the gas line to the gas connection or expansion joint free of
stress.
Secure the gas line with pipe clips so that the gas connection is free
from any stresses.
Close gas isolator.
Gas filters must always be installed to prevent ingress of dirt into the gas
line of the floor standing boiler.
