1. Clean burner and combustion chamber.
2. Check pilot and burner gas supply.
3. Check condition of ignition sensing probe.
4. Check boiler pipework joints for leaks.
5. Check the case seals.
6. Check condensate pipework for leaks.
7. Check heat exchangers, and the flue and air
duct are clear of any obstruction, and not leak-
ing.
8. Check the Fan and its seal.
9. Check and clear the condensate exit on the
secondary heat exchanger by removing the
Condensate Outlet and the Inspection

Follow the procedures given in Changing Com-
ponents for parts removal in addition to the fol-
lowing notes.
1.Heat Exchangers
Remove the panel in front of the secondary
heat exchanger to gain access to inner inspec-
