General Information
General Note
This boiler is designed for use as part of a sealed water cen-
tral heating system with fully pumped circulation. The pump,
expansion vessel and associated safety devices are all fi tted
within the boiler.
Once the controls are set the boiler operates automatically.
Please read these instructions and follow them carefully for the
correct installation and economical use of your boiler.
Water Treatment
In the case of an existing system, it is ESSENTIAL that prior to
installing the new boiler the system is thoroughly fl ushed. For
optimum performance after installation of a new system, the
boiler and its associated central heating system should also
be fl ushed. Flushing should be carried out in accordance with
BS7593: 1992 using a cleanser such as Sentinel X300 or X400,
Fernox Restorer or Salamander corrosion guard cleaner.
For long-term corrosion protection, after fl ushing, a suitable in-
hibitor should be used, refer to the current issue of BS 5449
and BS 7593 on the use of inhibitors in central heating sys-
tems. Examples are Sentinel X100 Fernox Protector or Sala-
mander corrosion guard inhibitor.
Compartment or Cupboard Installations
If the boiler is fi tted into a compartment or cupboard it does not
require ventilation openings.
Do not use the compartment or cupboard for storage.
Clearances
If fi xtures are positioned close to the boiler, space must be
left as shown in diagram 2.1.
Condensate Drain
The condensate drain, see diagram 8.2, must not be modifi ed
or blocked.
Pluming from fl ue terminal
Like all boilers with a fl ue heat exchanger, this appliance will
produce a plume of condensation from the fl ue terminal in cool
weather. This is due to the high effi ciency and hence low fl ue
gas temperature of the boiler. It is normal and not a fault indi-
cation.
Electrical Supply
If the mains electricity and gas are to be turned off for any long
periods during severe weather, it is recommended that the
whole system, including the boiler, should be drained to avoid
the risk of freezing.
NOTE: Contact your installation/servicing company as drain-
ing, refi lling and pressurising MUST be carried out by a com-
petent person.
Manual Handling
IMPORTANT: With regards to the “Manual Handling Opera-
tions, 1992 Regulations”, the appliance exceeds the recom-
mended weight for a one man lift.
