N.B. Technical Bulletins are also available on our website.WARNING. Always turn OFF the gas supply at the gas service cock, and switch OFF and disconnect the electricitysupply to the appliance before servicing.The servicing procedures are covered more fully in Frames 49-56 and MUST be carried out in sequence.Note.In order to carry out either servicing or replacement ofcomponents the boiler front panel and sealing panel must beremoved. Refer to Frames 49 and 50.IMPORTANT.9. After completing the servicing or exchange of componentsalways test for gas tightness.10. When work is complete the sealing panel MUST becorrectly refitted, ensuring that a good seal is made.Do NOT OPERATE the boiler if the sealing panel is not fitted.11. If, for any reason, the condensate ‘S’ trap has beenremoved ensure the trap is refilled with water beforereassembling.12. Check the gas consumption.13. Connect a suitable gas analyser to the sampling point onthe top of the boiler (refer to Frame 49) or into the flueterminal if access is possible (optional test).For correct boiler operation, the CO/CO 2 content of the fluegas should not be greater than 0.004 ratio.14. Complete the service section in the BenchmarkCommissioning Checklist.To ensure the continued safe and efficient operation of theappliance it is recommended that it is checked at regularintervals and serviced as necessary. The frequency ofservicing will depend upon the installation condition and usagebut should be carried out at least annually.It is the law that any service work must be carried out by a GasSafe Registered Engineer. In IE service work must be carriedout by a Registered Gas Installer (RGII).1. Light the boiler and carry out a pre-service check, noting anyoperational faults.2. Clean the main burner.3. Clean the heat exchanger & ‘S’ trap.4. Check the condition of the combustion chamber insulation.Any cracked, damaged or displaced pieces should bereplaced. Ionisation probes are a servicable componentand require inspecting annually. Replace if distorted.5. Check the main injector for blockage or damage.6. Wherever possible remove and clean the condensate ‘S’trap (refer to Frame 54) and check the drain for blockage.7. Check that the flue terminal is unobstructed and that theflue system is sealed correctly.8. Check the DHW filter for blockage. Refer to Frame 33.SERVICING
