Condensate Drain
The condensate drain, see section 7.3, 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.
Cleaning
The boiler casing can be cleaned using a mild
liquid detergent with a damp cloth, then a dry
cloth to polish.
Do not use any form of abrasive or solvent cleaner
as you may damage the paintwork.
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: If you have a sealed water system contact
your installation/servicing company as draining,
refilling and pressurising MUST be carried out by
a competent person.
MANUAL HANDLING
IMPORTANT: With regards to the Manual
Handling Operations, 1992 Regulations, the
following lift operation exceeds the recommended
weight for a one man lift.
General recommendations when
handling
Clear the route before attempting the lift.
Ensure safe lifting techniques are used – keep
back straight – bend using legs.
Keep load as close to body as possible.
Do not twist – reposition feet instead.
If 2 persons performing lift, ensure co-ordinated
movements during lift.
Avoid upper body/top heavy bending - do not lean
forward/sideways.
Recommend wear suitable cut resistant gloves
with good grip to protect against sharp edges and
ensure good grip.
Always use assistance if required.
APPLIANCE SAFETY DEVICES
- USER INSTRUCTIONS
Electrical Supply Failure Reset
Switch
The boiler will not work without an electrical
supply.
Normal operation of the boiler should resume
when the electrical supply is restored.
Reset any external controls, to resume normal
operation of the central heating.
If the boiler does not resume normal operation turn
the mains reset switch off and on. If the boiler
does not resume normal operation after this the
overheat stat may have operated.
Overheating Safety
In the event of the boiler overheating the
safety devices will cause a safety shutdown.
If this happens, call your Installation/Servicing
company.
Frost Protection
The appliance has a built in frost protection
programme as long as the electricity and gas are
left switched on.
This device operates the burner and system
pump when the temperature inside the boiler
falls to 3°C.
Any other exposed areas of the system should be
protected by a separate frost thermostat.
