12 GLOSSARY

Central heating systems

All radiators must be heated at an even rate. If the top of a radiator is at a lower temperature than the 
bottom then it should be vented by releasing air through the venting screw at the top of the radiator. 
Ask your installer to show you how this is done.

This boiler is fitted to a sealed system. Should water leaks be found or if excessive venting is required, 
then a service engineer must be contacted to inspect the installation and rectify any fault.

Only additives that are compatible with aluminium may be used in the system. Any incompatible 
additive used will invalidate the guarantee.

Pluming and Condensate drain

This is a condensing boiler and the flue terminal will, at times give out a plume of water vapour. This 
is quite normal.

The boiler produces condensate which is discharged regularly by a syphon within the boiler via a 
plastic pipe to a drain. This pipe must not be blocked or altered in any way.

Room thermostat / programmer

A room thermostat / programmer must be fitted to control the central heating. This controls the times 
and temperatures of the central heating, preventing the boiler from firing unnecessarily. Refer to the 
instructions supplied with the thermostat and programmer for further information.

Thermostatic radiator valves

Thermostatic radiator valves must be fitted in sleeping accommodation. It is recommended that this 
type of valve is fitted to all but one of the radiators. The remaining radiator, where the room thermostat 
is located, must be uncontrolled and left open.

Pump over run function

After the boiler has finished a demand for central heating or hot water, the pump continues to run for 
three minutes to dissipate the heat from within the boiler.

Pump anti-seizure

If there has been no heating demand for 24 hours the boiler will run the system pump for a few seconds 
to reduce the possibility of pump seizure during long periods of inactivity.
