• Adjust heating temperature to maximum 87 ° C.
• 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 temperature rise will cause release
of the gases contained in the water of the central heating
system.
• Gases driven towards the boiler will be automatically released
through the automatic air vent.
• The gases trapped at the highest point of the system must be
released by bleeding the radiators. Check the burner gas rate
required, ten minutes from lighting. Refer to Data Label on
electrical controls box. Should there be any doubt about the
gas rate it should be checked at the meter.
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 temperature is
reached. Shut down boiler and vent heating system. If necessary,
top up heating system and make sure that a pressure of at least
1 bar is indicated when system is COLD.
To stop the boiler: Press button 1.
