Central Heating Fig. 1. System Diagram. Automatic air vent When a demand is made for heating by the system controls (i.e. a programmer or room thermostat).

The heat output from the appliance in this mode has been factory set to mid-range or as reset by your installer.
GENERAL NOTES CENTRAL HEATING SYSTEM During the first few hours of operation of the central heating system, check that all radiators are being heated at an even rate. Should the upper area of a radiator be at a lower temperature than the base of the radiator, it should be vented by releasing air through the venting screw at the top of each radiator. Make sure your installer shows you how to carry out the operation.
