MAINTENANCE
To ensure the continued effi cient and safe operation of the
boiler it is recommended that it is checked and serviced at
regular intervals. The frequency of servicing will depend upon
the particular installation and usage, but in general once a year
should be enough.
It is the Law that any servicing is carried out by a competent
person approved at the time by the Health and Safety
Executive.
• Before commencing with a service or replacement of parts
isolate the boiler from the electrical supply and turn off the
gas supply at the gas isolation valve.
• When replacing a part on this appliance, use only spare
parts that you can be assured conform to the safety and
performance specifi cation that we require. Do not use
reconditioned or copy parts that have not been clearly
authorised by Heatline.
• If any electrical connections have been disconnected and
after their connection, checks to the earth continuity, polarity,
short circuit and resistance to earth must be repeated using a
suitable multimeter, as described in chapter "Trouble-shooting
► Fault diagnosis ► Check the electrical installation".
• After servicing, complete the relevant Service Interval Record
section of the Benchmark Checklist located in the back pages
of this document.

15.1 Fault diagnosis
The following checks should be performed before proceeding
onto specifi c diagnostics:
• Make sure that the electricity supply has not been interrupted
and that the appliance is connected correctly (See chapter
"Trouble-shooting ► Fault diagnosis ► Check the electrical
installation")
• Check the appliance’s gas supply (See chapter "Troubleshooting
► Fault diagnosis ► Check the gas supply").
• Ensure that the isolating valves are open.
• Check the external electrical supply to the boiler is on and a
supply of 230V is present at the ‘L’ and ‘N’ terminals on the
main board.
• Check the electrical installation and appliance, carry out tests
for earth continuity, polarity, short circuit and resistance to
earth, using a suitable multimeter.
• Check the link FP –RT is secure or the connected control,
connected at these points, is functioning correctly.
• Bare metal points such as screws or rivets will act as suitable
earth check points on the appliance.
• Ensure that the pressure indicator displays a value of 1.0 bar
(if the pressure falls below 0.4 bar, the air vent function will
run automatically for a period of 5 minutes until you see 0.5
bar on the pressure indicator). If not, re-charge the system.
• Check that all external controls are connected correctly.
