When fitting service shut-off valves, position the filling and drain valve,
the expansion vessel and the safety valve between the shut-off valve
and the boiler.
Carry out any welding work required at a safe distance from the boiler or
before the boiler is fitted.
For filling and tapping the boiler, install a filling and drain valve in the
system, preferably in the return.
Install an expansion vessel in the return pipe.
The siphon must always be filled with water. This prevents flue gases
from entering the room.
