► Flush the installation thoroughly to clean (please refer to
current Standard Codes of Practice).
► Fit the cold and hot water pipes into the shut o valve and
the elbow.
► Existing connections must not be twisted, in order to avoid
leakages. Make sure the compression fittings are tightened
thoroughly to prevent leakage.
Comments
► The specific pipeline length with a piping diameter of
12/10mm or 15/13mm is 30 meters and 17.7 meters,
respectively.
► If the boiler is only used for the domestic hot water facility,
the heating function can be switched o. Parameter P001
must then be changed from 0 to 2. In this case, the central
heating system does not need to be connected or filled.
► If the boiler is out of order and disconnected from the
electricity network during the winter months, the water
must be drained to prevent freezing. Disconnect the
domestic hot water connections immediately directly under
the boiler.
► The Xtreme 24 is equipped with a flow restrictor with a
nominal value of 8l/min. The Xtreme 30 and Xtreme 36 do
not have this feature. If desired, this can be ordered from
Intergas as an option.
The Xtreme 36 allows larger volume flows with high water
pressures; to ensure an exhaust temperature of 55°C, the
DHW facility has to be set at 9 l/min.
