• Ensure the cold water service valve (2) is open. This
can be checked by opening a hot water tap and ensu-
ring water flows.
• Ensure that the service valves in the heating flow and
return (4 and 3) and the gas service valve (1) are open.
The flow, return and gas service valves are open when
the line marking has the same direction as the pipe.
Attention!
The pressure relief valve is provided for safety
reasons and must not be interfered with.
