Our definitions of a Gas Appliance Service

• check burner pressure/gas rate against data plate figures and adjust where necessary.

• check condition of combustion chamber seats (where appropriate).

• check for satisfactory flue arrangements (includes inspection of catchment’s space where appropriate).
