meeting the requirements of BS7927

or BS-EN50379-3 and be calibrated

in accordance with the analyser

manufacturers requirements, and

* Competence can be demonstrated by

satisfactory completion of the CPA1

ACS assessment which covers the use

of electronic portable combustion gas

analysers in accordance with BS7967,

parts 1 to 4.

Conduct a flue gas analysis as detailed

in Appendix 2.

See 4.5.1 “Chimney sweep” for details

how to set the boiler to minimum and

maximum outputs.

4.8.2 Burner inspection

– Isolate from mains

– Remove case cover

– Isolate gas

– Drop down control case

– Remove ignition and ionisation lead

– Disconnect gas pipe from gas valve to

burner mixing arm,

– Disconnect air sensing tube

– Remove air inlet to fan and disconnect

the fan wiring

– Remove the four nuts securing the

burner to the heat exchanger.

– Carefully lift out the burner.

– Check seals and replace if necessary

– Replace in reverse order

Test for gas tightness.

4.8.3 Combustion Chamber

Remove any loose debris from the

combustion chamber using a soft brush

and a vacuum cleaner.

Take care not to damage the rear

insulation panel.

4.8.4 Condensate Trap

The condensate trap would not normally

require removal during service, but can

be checked whilst the burner assembly

is removed.

Carefully pour water into the heat

exchanger and check that it flows freely

to the drain.

Should it require removal, firstly

remove the two wire clips securing the

condensate drain rubber pipe to the heat

exchanger and the condensate trap.

Remove the pipe.

Remove the 1/2” nut securing the

condensate trap to the bracket.

Disconnect the drain pipe from the trap.

Clean the trap and refit in reverse order.
