Adjust heating temperature to maximum .
Check that any external controls, if fitted, are
calling for heat (set room thermostat to maximum).
Allow the temperature to rise to the maximum
value, with all radiator valves open. The tempera-
ture rise will cause release of the gases contained
in the water of the central heating system.
Gases driven towards the boiler will be automati-
cally released through the automatic air vent.
The gases trapped at the highest point of the sys-
tem must be released by bleeding the radiators.
On reaching maximum temperature, the boiler
should be turned off and the system drained as
rapidly as possible whilst still hot.
Refill system to a pressure of between 1 and 2
bar and vent as before.
Restart boiler and operate until a maximum tem-
perature is reached. Shut down boiler and vent
heating system. If necessary, top up heating sys-
tem and make sure that a pressure of 1 bar is indi-
cated when system is COLD.
