Initial checks before
turning ON
Open the service valves
● Ensure the cold water service valve
is open. This can be checked by
opening a hot water tap and
ensuring water flows.
● Ensure that the service valves in
the heating flow and return (2 and
1) and the gas service valve (3)
are open.
☞
The flow, return and gas
service valves are open when
the line marking has the same
direction as the pipe.
● The pressure relief valve (4) is
provided for safety reasons and
must not be interfered with.
Note:
A bottom cover is fitted to the
appliance. The service valves can
be seen through the cover.

Plus boiler
Indicator lights/boiler display
TURBOmax Plus and THERMOcompact
boilers have an advanced multi-
function boiler display (1). When the
main ON/OFF control is in the „ON“
position the display will normally
show the temperature of water in the
boiler circuit (45 °C in the example),
which confirms that the boiler is
functioning correctly.
1 In the unlikely event of a fault
developing which prevents the
boiler from operating, the display
may show a fault code (page 14).
