General notes
To get the best from your appliance. please read these
instructions carefully.
5.3.1 Central heating systems
During the first few hours of operation of the central heating
system, check that all radiators are being 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. Repeated venting will reduce the
quantity of water in the system and this must be replenished for
safe and satisfactory operation of the boiler.
When excessive venting or water leaks are found in the system
you must contact a service engineer to inspect the installation
and rectify any fault.
Only use additives compatible with the boiler and system. Use
of incompatible additives can cause damage and will invalidate
the boiler guarantee.
5.3.2 Pluming and condensate drain
This is a condensing appliance and the terminal will, at times
give out a plume of water vapour. This is quite normal.
The appliance also produces quantities of condensate which is
discharged regularly via a pipe to a disposal point.
This pipe must not be blocked or altered in any way.
