To get the best from your appliance please read these instruc-
tions carefully.
Sealed heating systems
The appliance is fitted to a sealed heating system which is pre-
pressurised. Your installer will tell you of the minimum and maxi-
mum pressure which must be indicated on the pressure gauge.
Check regularly that the pressure is maintained and contact your
installer or maintenance engineer if there is a permanent signifi-
cant drop in the pressure. If the system loses pressure it should
be repressurised and the cause of the fall investigated.
Central heating systems
During the first few hours of operation of the central heating sys-
tem, 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 appliance.
Should water leaks be found in the system or 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.
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 produces quantities of condense which is dis-
charged regularly through the siphon.
