Intergas XTREME 36 - Boiler with Pre-Heated Solar Boiler)

24
Domestic hot water inlet pressure:
For a flow volume of 20 litres per minute, the initial pressure
must be a minimum of 2.3 bar. The allowed domestic hot
water operational pressure for the combination may be a
maximum of 6 bar. A safety group (6 bar) must be installed for
this purpose.
Maximum flow volume:
If the domestic hot water flow is greater than 20 litres per
minute, the Intergas Xtremewill start domestic hot water
demand, regardless of the exhaust temperature of the heat
pump boiler.
Maximum temperature setting of the heat pump boiler:
The temperature of the heat pump boiler may not be set higher
than 60°C.
Position of thermostatic switch valve:
To prevent the thermostatic switch valve being influenced too
much by the surrounding air, this valve must be placed in a
vertical position and as close as possible to the domestic hot
water connection of the boiler (maximum distance of 100mm).
This prevents the boiler operating with each tap request.
Influence of water flows:
To prevent the flow being influenced by the Intergas
Xtremeduring the switching of the valve, the domestic hot
water ‘out’ pipeline of the combination must run straight (see
connection diagram [F]).
6.2.3 Boiler with Pre-Heated Solar Boiler)
A connection set and a thermostatic mixing valve are available
to order for this purpose.
Comment:
The cold water sensor must be connected to Connector X13
4/5. When combined with a solar energy system, a thermostatic
mixing valve, set at 62.5°C, must always be placed aer the
boiler.
