Set up
Control measures
The first set up must be performed
by an authorised expert.
Before set up, the following checks
must generally be performed:
x Check power supply
x Check pressure in the heating
system
x Check pressure at the gas con-
nection
x Check gas pipe seal
x Check perfect assembly of the
exhaust accessories
x Check condensation pipe seal
Minimum circulation quantity / flow
monitoring
It must be guaranteed that the device
has a hydraulic throughflow when
feeding heat. The device is fitted with
a flow safety which monitors the
throughflow. In order to maintain the
minimum throughflow, it is recom-
mended that points or a plate heat
exchanger be fitted (both available as
accessories) or the RENDAMAX 30 is
connected to an open distributor.
Before installation, please note the
following:
x The size of the expansion tank
must be sufficient, see notes on
the water quality, if necessary fill
with softened water.
x The system should be set up
directly after filling in order to rule
our standing air cushions as a
corrosion ovens.
x Chalk deposits in the heating boiler
are avoided by setting up the
device at low system temperatures
and maximum throughflow.
x During revision work, a complete
exchange of the system water
should be avoided. This can be
achieved through partial dams or
reuse of the trapped and filtered
system water.
