Filling
The filler connection (79), 15 mm copper pipe, is connected
to the system's fresh water pipe. When filling the heating
system, the filler valve (49) is opened, whereby the system
is filled with water. Observe the pressure rising on the
pressure gauge. When the indicator reaches 2.5 bar, the
safety valve opens (52) and starts to release air mixed with
water. Stop the filling. Turn the safety valve until the boiler
pressure reaches the normal working range (0.5-1.5 bar).
Venting
The boiler is vented through the safety valve (52). The rest
of the heating system is vented through their respective
vent valves.
NOTE
The safety valve must be operated very carefully be-
cause it opens quickly.
Secondary adjustment
After venting is completed the pressure must be adjusted.
Suitable pressure is approx. 1.2 bar if the system is hot and
approx. 0.6 if the system is cold. Air is initially released from
the hot water and venting may be necessary. If gurgling
sounds can be heard from the boiler, the entire system
requires additional venting. When the system is stable
(correct pressure in the boiler and all air eliminated) the
automatic heating control system can be set as required.
See section "Heating control system" on page 7 and
“Front panel" on page 5.
