Victrix 24kW X Instructions
The boiler has two sets of flow/return connections. One set is used for connection to the central system
while the other set is connected to the coil of the domestic hot water heating tank. The boiler incorporates
a diverter valve which diverts all flow to heat the DHW tank when the temperature of the hot water tank is
below the temperature set on the boiler. The optional 3 way valve kit ACB515 and the sensor must be fit-
ted to the tank in order for this feature to work.
Alternatively, if hot water priority operation is not required, the boiler may be plumbed as shown below. In
this type of installation, the DHW flow and return connections should be capped or connected to each other.
If a hot water heating tank is connected as shown below, then it will not be possible to use the boiler’s
weather compensation feature as the boiler flow temperature may not be sufficient to heat the hot water
tank adequately. The hot water only position on the boiler is not in use for this configuration.
Filling the central heating system
The system design pressure (cold) should be set to 1.0 bar. This pressure is equivalent to a static head of
10.2 metres of water. Provision should be made to replace water lost from the system. This can be by
manual or automatic means.
Filling of the system must be carried out in a manner approved by the local authority. Where allowed, the
system may be filled via a temporary connection as shown below or by using the integrated filling valve in
the boiler. After filling, always disconnect the flexible hose of the filling loop if used and close the filling
valve in the boiler.
All fittings used in the system must be able to withstand pressures up to 3 bar. Drain taps (to BS 2879)
must be used to allow the system to be completely drained. The heating system should be thoroughly
flushed before the boiler is connected and again after the first heating. If it is necessary to add inhibitor to
the central heating system, contact RVR Ltd. for guidance.
