Inlet Pressure
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
