Circulation pump radiator system

Pressure release valve for the boiler

Fillet valve radiator system

Pressure gauge, system pressure

Connection of the expansion vessel
Assembly of 18 l
expansion vessel
The circulation pump must be mounted on the primary flow of the boiler and is electrically
connected from the boiler, se Electric installation .
A pressure release valve for the boiler is factory mounted. The waste pipe has to be
connected to a drain gutter directly, or if the distance is more than 2 m, to the waste funnel.
The waste pipe must lean toward the drain gutter.
To be mounted between the cold water connection and the radiator return
pipe (alternative: between the cold water and the expansion connection).
A pressure gauge must be mounted on the expansion pipe, alternatively on
the return pipe of the radiator.
The boiler can be connected to a closed expansion vessel (closed system is recommended) or
to an open vessel. The boiler is ready for assembly to an 18 l closed vessel, placed compact
on top of the boiler. The expansion vessel, with required angle connection, can be bought as
an accessory.
Connect a system pressure gauge to the return pipe of the radiator.
If another expansion vessel is chosen, the pressure gauge is often included.
With an open system, the height between the highest placed radiator and the
expansion vessel must not be less than 2,5 m to avoid air getting into the
system.
