1.Ensure that all controls are calling for heat and maximum load is applied to the system.
2.With the boiler operating in the maximum rate condition check that the operational (working) gas pressure at the inlet gas pressure test point is in accordance with B.S. 6798 & B.S. 6891.
3.Ensure that this inlet pressure can be obtained with all other gas appliances in the property working.
Measure the Gas Rate
4.With any other appliances & pilot lights turned OFF the gas rate can be measured. It should be as shown in Section 4.0 Technical Data.
5.Carefully read and complete all sections of the Benchmark Commissioning Checklist at the rear of this publication that are relevant to the boiler and installation. These details will be required in the event of any warranty work. The publication must be handed to the user for safe keeping and each subsequent regular service visit recorded.
