To perform a gas pressure test

1 Connect a suitable gauge on the gas valve. Static pressure
MUST be 20 mbar.
2 Select test program " ". See
the gas boiler" on page 82. Static pressure MUST be 20 mbar
(+ or – 1 mbar). If the working pressure is <19 mbar, the gas
boiler output will be reduced and the correct combustion
reading may NOT be obtained. Do NOT adjust the air and/or
gas ratio. To obtain sufficient working pressure, gas supply
MUST be correct.
INFORMATION
Make sure the working inlet pressure does NOT interfere
with other gas appliances installed.

To perform a test run on the gas boiler
