note
.
Some aluminium oxide build-up within the heat exchanger
assembly is quite usual with this type of condensing boiler.
Though removal and cleaning is recommended annually,
the heat exchanger, sump and condensate trap must
be inspected and cleaned after a maximum of 2 years
operation.
1.
Light the boiler and carry out function checks, noting
any operational faults.
2.
Run the boiler for 5 minutes and then check the gas
consumption rate. Refer to procedure opposite on how
to force the burner to maximum rate.
3.
Optional test - Connect a suitable gas analyser to the
sampling point fitted in the flue adapter. For correct
boiler operation the CO/CO
2
ratio of the flue gas should
not be greater than 0.004 ratio and the CO
2
values
should match those in table 1. If this is the case and
the gas input is at least 90% of the nominal, once
compliance with the note above is ensured, then no
further action need be taken. If not proceed to 4.
4.
Remove and clean the burner. Refer to Frames 59 and
60.
5.
Inspect the heat exchanger through the burner opening.
If there are signs of aluminium oxide build up, spray
water down the flueways. Refer to Frame 60.
6.
Remove the sump cover and scrape out any deposits.
Refer to Frame 61.
7.
Remove the condensate trap and flush through with
water. Refer to Frame 62.
8.
Check that the flue terminal is unobstructed and that the
flue system is sealed correctly.

After completion of servicing refer to Frame 55 for
reference to final safety checks.
