8 Inspection and maintenance
DANGER:
Risk of electric shock!
▶ Isolate electrical components from the power supply (230 V AC)
(fuse, circuit breaker) and secure against unintentional re-
connection before carrying out any work.
Information on safe isolation can be found in the Health and Safety
Executive guidance HSG85.
▶ Check for zero potential before proceeding with work, using test
equipment approved to GS38 to confirm that the electricity supply is
disconnected.
CAUTION:
Mains supplies:
▶ Safely isolate both the gas and electrical supply before starting any
work on the appliance and observe all relevant safety precautions.
NOTICE:
Personnel and equipment
▶ Any service work must carried out by competent registered
engineers.
▶ Service work must not be attempted if a calibrated CO/CO
2
analyser
and manometer are not available.
WARNING:
Hot surfaces!
If the appliance has been operating components may be hot.
▶ Ensure precautions are taken when working on the appliance.
CAUTION:
Component replacement:
▶ After replacement of a gas related component, where a gasket or seal
has been disturbed or replaced, check for gas tightness using a gas
sniffer/analyser.
▶ Also after re-assembly, carry out the following checks:
Fan pressure.
Flue gas analysis.
8.1 Inspection and maintenance considerations
• To ensure continued efficient operation the appliance must be
checked at regular interval.
• The frequency of servicing will depend upon the particular
installation conditions and usage, however, normally an annual
service is recommended.
• The extent of the service work required by the appliance is
determined by the operating condition of the appliance when tested
by qualified engineers.
• After each service, the service interval record sheet at the rear of this
manual, must be completed.
See the following instructions for detail of some of the service
requirements:
▶ Check all joints and connections in the system and remake any that
show signs of leakage. Refill and re-pressurise if applicable as
described in the commissioning section.
▶ Check that the condensate system is not obstructed, clean and refill
the condensate siphon.
▶ If the appliance is in a compartment or cupboard check that the
specified clearances around the appliance is clear.
▶ Check that the flue system is unobstructed and undamaged, clean/
replace as necessary.
– If fitted ensure the flue terminal guard is also unobstructed and
undamaged.
▶ Operate the appliance and take note of any irregularities.
– Refer to the fault finding pages for rectification procedure.
8.2 Resources for inspection and maintenance
• The following measuring devices are required:
– Electronic flue gas analyser for CO
2
, O
2
, CO and flue gas
temperature
– Pressure gauge 0 - 30 mbar (minimum resolution 0.1 mbar)
▶ Use heat conducting paste 8 719 918 658 0.
▶ Use approved greases.
