Hi all, I'm a RGI who is wondering what sort of checks & procedures other CORGI engineers perform when servicing boilers. To a question like this there is obviously no 'right or wrong' answer, but it would be useful to me to see how much (or little) other service engineers do.
I only ask as I have heard some other contributors saying that they go as far as stripping down diverter valves and removing and flushing DHW heat exchangers during their usual boiler services. As I work for a company who expect us to service 8+ boilers a day between Central London & Middlesex this much involvement would not be possible. I also would worry about the possibility of damaging o-rings, washers & gaskets when removing some components on older boilers, as you can never have everything in the van you inevitably would need.
I generally follow this kind of procedure:
Tightness test & visual inspection
Check correct operation of boiler
Remove burner & clean, clean pilot assy & electrodes (where present)
Clean heat exchanger
Check free movement of fan & venturi (where present)
Check free movement of flow switches where present
Check safety devices
Check gas pressures (where possible) & gas rate
Is this normal or do others go much further on annual service visits?
Cheers
