11 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 bled
by releasing air through the bleed screw at the top of the radiator.
You must re-pressure the system after venting the radiators.
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 bleeding 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.
Optional Integral Diverter Valve
When the Integral Diverter Valve accessory is installed, the
demands for central heating and hot water can be controlled from
the boiler. The flow temperature for the domestic hot water
cylinder can be set and adjusted using the hot water temperature
control on the boiler fascia.
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.
