Total hardness of the water
(1) For installations that are heated at constant high temperatures with a total installed heat output up to 200 kW, maximum total water
hardness of 8.4°dH (1.5 mmol/l, 15°f) applies and for above 200 kW a maximum total water hardness of 2.8°dH (0.5 mmol/l, 5°f) applies

The gas leakage control checks and controls the safety valves on the gas
valve unit. The test takes place before the boiler starts up. In the event of
a leak in the gas valve unit, the boiler will lock out. The pressure switch
must be set at 50% of the supply pressure (see table below).

In many cases, the boiler and central heating system can be filled with
normal tap water and water treatment will not be necessary.
For optimum functioning of the boiler, the water in the installation must
comply with following characteristics:

1. Connect the gas leakage control to the VPS terminals of the terminal
strip.
2. Set the presence of the gas leakage control using a parameter setting.

Water treatment

Warning
Do not add chemical products to the central heating water without
first consulting a water treatment professional. For example:
antifreeze agent, water softeners, pH-increasing or -lowering
agents, chemical additives and/or inhibitors. Such agents can
cause faults in the boiler and damage to the heat exchanger.
