7.1 ROUTINE INSPECTION INTERVALS & REQUIREMENTS
Health and Safety Statement
: This boiler contains no asbestos.
In all cases, before work commences turn off the mains electricity and gas supply.
To ensure continued efficient 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 of the boiler, therefore a service after
4,000 hours
of burner
operation is recommended, with a minimum requirement to annually service the boiler every
twelve months from initial commissioning date.
It is a legal requirement that any service work or maintenance should be
carried out by competent registered personnel.
7.1.1 Minimum inspection requirements
During routine inspection and servicing and after any maintenance or change of part of the
combustion system, the following actions
must
be performed:
• Check the integrity of the combustion chamber, relevant seals and heat shields
• Check condition of ignition spark and sensing electrodes
• Check the integrity of flue seals
• Check condensate syphon and pipe work for leaks
• Check the combustion CO, CO
2
and gas running pressure
• Clean out filter/strainer in return system
• Check the water inside the boiler is free of air and the automatic air vent operation
• Follow the procedures given in section 7.3 for full details on inspection and parts re-
moval.
Once maintenance has been completed, it is recommended that the counters for
burner hours since maintenance and time since maintenance are reset
(parameter lines

7.1.2. Recommended inspection operation
It is recommended that the following actions should be carried out prior to shutting down
the boiler before servicing work is carried out:-
- Check the starting and running of each combustion fan.
- Check for smooth ignition of each heat engine.
- Check for gas and products of combustion leakages when operating.
- Check for signs of fluid leakages, either from condensate or water channels
- Inspect flue, joints must be sound and correctly supported and there must be sufficient
fall back to allow condensate to run back to the boiler.
- With the boiler operating at a low return temperature (below 50
o
C) check that
condensate flows freely from the condensate line.
-Carry out analysis of system water to ensure good water quality (see section 4.4.3)
