Inlet Gas Pressure Test Point

DO NOT check gas pressure here

1. It may be necessary to adjust the boiler gas type if the supply is changed, for example

when Natural Gas is provided to a rural area previously reliant on Propane. In these

instances a replacement Gas Type Label may be required, which is available on request

as a spare part.

2. Press & and hold for at least 6 seconds. will be displayed,

10.2 Check the Operational (Working) Gas Inlet

Pressure & Gas Rate

Note: The system MUST be cold to ensure the boiler is

operating under full demand. To obtain an accurate

measurement on smaller capacity systems it may be

necessary to open one or more hot taps in order to

maintain the boiler at full rate.

1. Press & together and hold for at least 6

seconds.

‘On’ will be displayed briefly, followed by ‘304’

then ‘100’ when the boiler is lit, indicating the CH output is

at MAXIMUM (‘Chimney Sweep Function’).

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. This must be AT LEAST 17mb ! (LPG - 37mb)

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:-

Natural Gas 24 model 2.54 m

28 model 2.96 m

33 model 3.49 m

40 model

4.23 m

Propane 24 model 1.92 kg/h

28 model 2.25 kg/h

33 model 2.64 kg/h

40 model 3.2 kg/h

5. Press & together and hold for at least 6

seconds to exit the function.

6. 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.

7. For IE, it is necessary to complete a “Declaration of

Conformity” to indicate compliance with I.S. 813. An example

of this is given in I.S. 813 “Domestic Gas Installations”. This is in

addition to the Benchmark Commissioning Checklist.
