measurement. The gas pressure for the water heater, to operate properly under the correct load, must be at least 20 mbar.
The graphs below show the position of the pressure nipple (3) for the complete water heater range.

When mounting the bottom part of the siphon, before commissioning the boiler and/or after maintenance,
it must ALWAYS be completely filled with water.
This is a safety measure: the water in the siphon keeps the flue gases from leaking out of the heat
exchanger via the condensate drain.
When the water heater receives a heat demand the electronics will start the operation of the water heater. Before the water heater is used,
the water heater burner must be adjusted and set at the minimum and maximum load.
