Domestic hot water inlet pressure:
For a flow volume of 15 litres per minute, the initial pressure
must be a minimum of 2.3 bar. The maximum static domestic
hot water pressure for the Xclusive is 5 bar. A pressure
reducing valve (set to 3 bar) must be installed to prevent
excessive build up, it must be located no closer in proximity to
the boiler than 3 meters (for expension purposes).
Maximum flow volume:
If the domestic hot water flow is greater than 20 litres per
minute, the Intergas Xclusive will start a domestic hot water
demand, regardless of the outlet temperature of the heat
pump unit.
Maximum temperature setting of the heat pump boiler:
The outlet temperature of the heat pump unit must not be set
higher than 60°C.
Position of thermostatic mixing valve:
To prevent the thermostatic mixing valve being influenced too
much by the surrounding air temperature, the valve must be
placed in a position and as close as possible to the domestic
hot water connection of the boiler (maximum distance of
500mm). This prevents the boiler from igniting every time an
outlet tap or shower is operated.
Influence of water flow:
To prevent the flow by the Intergas Xclusivebeing influenced
during operation of the valve, the domestic hot water ‘out’
pipework of the combination must run straight (see connection
diagram [F]).
7.2.3 Boiler with Pre-Heated Solar Boiler)
A connection set and a thermostatic mixing valve are available
to order for this purpose.
Comment:
The NTC cold water sensor must be wired to Connection X13
4/5. When combined with a solar energy system, a thermostatic
mixing valve, set at 55°C (max 60°C), must always be installed
aer the boiler for safety reasons.
