DEFINITION OF A GAS APPLIANCE SERVICE

The way specific operations are to be carried out will normally be defined in the manufacturers maintenance instructions but they will not necessary define the operations required to service the appliance. In the absence of manufacturer service instructions the following items should be addressed:

Dismantle and clean burner(s) and injector(s) and check for physical deterioration in both Dismantle and clean pilot assembly (where fitted) Inspect and clean flue ways in heat exchanger and check for physical deterioration. Inspect and clean combustion fan (where fitted) Check for water and electrical integrity (where appropriate) Check satisfactory operation of all safety devices. E.g. flame failure devices vitiation detectors. Fan proving systems. Check burner pressure/gas rate against data plate figures and adjust where necessary Check condition of combustion chamber seals (where appropriate) Check for satisfactory flueing arrangements (including inspection of catchment space where appropriate) Test to ensure flue flow and removal of products of combustion. Check satisfactory provision of ventilation. Investigate any other evidence of unsafe operation and report any apparent defects to a responsible person(s)

An appliance could not be deemed as having been serviced unless the above had been completed.
