4.1. Hydraulic connections
The boiler is intended for connection with an open expansion vessel network. The boiler can be
connected also with closed expansion vessel, if it is equipped with an overheating serpentine
(optional).
The boiler is intended for maximum working temperature 90
o
C and maximum pressure 3 bar
for boilers up to 500 kW, and 4 bar for bigger boilers.
When connected with a closed expansion vessel, its volume must be chosen double to a similar
installation on liquid or gas fuel.
If a connection pipe is not used, it must be sealed before water fill!

Additional safety equipment can be mounted at the
connection pipe T6. This can be a dual safety valve
(pressure and temperature) or a cooling valve.
Alternatively this pipe can be used for connection
with the expansion vessel.
