Make up water
It is necessary to provide for replenishing of the water lost by the sealed system. Refer to standard BS6798 for the
methods of filling and replenishing water in sealed systems. There must not be a direct connection between the central
heating system of the boiler and the water mains. For the use of water coming from the water mains and direct pres-
surisation of the system, refer to the local water management by-laws. This connection, if provided for, must be inter-
rupted after use.
The valve installed in the boiler shell is provided with a filling connector.
Attention - is drawn to the Model Water Byelaws.
Filling system
The boiler is provided with a special filling system. To
fill the system remove caps
“G” and install the remov-
able connection tube “E” . Fill the system by turning
both knobs “L“ until the pressure gauge “M“ reads a
pressure of 1 ÷ 1.5 bar. Close the knobs “L” and re-
move the connection tube “E” .
