General Information
General Note
This boiler is designed for use as part of a sealed water
central heating system with fully pumped circulation. The
pump, expansion vessel and associated safety devices are all
fitted 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 flushed.
For optimum performance after installation of a new system,
the boiler and its associated central heating system should
also be flushed. 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 flushing, a suitable
inhibitor should be used, refer to the current issue of BS
5449 and BS 7593 on the use of inhibitors in central heating
systems. Examples are Sentinel X100, Fernox Protector or
Salamander corrosion guard inhibitor.
Compartment or Cupboard Installations
If the boiler is fitted into a compartment or cupboard it does
not require ventilation openings.
Do not use the compartment or cupboard for storage.
Clearances
If fixtures 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 modified
or blocked.
Pluming from flue terminal
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal in cool weather. This is
due to the high efficiency and hence low flue gas temperature
of the boiler. It is normal and not a fault indication.
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. Make sure that, if fitted, the
immersion heater in the cylinder is switched off.
NOTE: Contact your installation/servicing company as
draining, refi
lling and pressurising MUST be carried out by a
competent person.
Manual Handling
IMPORTANT: With regards to the “Manual Handling
Operations, 1992 Regulations”, the appliance exceeds the
recommended weight for a one man lift.
