Open the DH flow and return isolation valves.
Manually open the DHW valve to allow water to flow by pushing the white lever

Open the CH flow and return isolation valves and allow DH water to flow into the
system. Vent each radiator etc to remove any air and check for water

Open a hot water tap and check that the DHW valve opens, the CH valve closes
and hot water is supplied. Set the outlet temperature as required by adjusting
the thermostat’s knob (Setting 9 gives approximately 55 to 60’C). Turn off the
