Fig. 5.8 Measuring the gas inlet working pressure
> Loosen the sealing screw marked “in” (1) on the gas
valve.
> Connect a digital pressure gauge or U-tube manome-
ter (2).
> Open the gas isolation valve of the boiler.
> Start the boiler by activating the test program P.1 as
described in section 8.2.
> In addition, ensure that maximum heat can be dissi-
pated into the heating system by turning up the room
thermostat.
> Alternatively, for ecoTEC combination boilers fully
open the hot water taps to ensure full flow rate
through the boiler.
> With the boiler operating at full load check that the
gas inlet working pressure at the reference test
point (1) complies with the requirements of Table 5.2.
