bottom where the boiler will be mounted. For
water connections, a filter and a ball valve must be
installed at the inlets of the combi. (Figure 5) The
mains inlet should not be over the 8 bar pressure
limit. In cases with higher network pressure, a pressure reducer must be installed.
The suitability of the gas installation and the device should be checked.
Warning: The safety valve connection must be
given to the installation drainage line.
