operating mode . If the CO
2
reading is incorrect,
the maximum gas pressure must be adjusted as
follows:
● Using a suitable screwdriver, very slowly turn
the maximum adjustment screw (fig. 30) –
clockwise to increase, counter clockwise to
decrease – until the correct value is displayed
on the CO
2
analyser (allow time for the analyser
to stabilise).
● Using the procedure detailed in section 7.4,
change the power momentarily from maximum
to minimum, then back to maximum.
● Check that the correct value is still being
obtained. If not, repeat the above procedure.
● Press the
+
and
-
buttons at the same
time to return to the normal operating mode.
Isolate the appliance from the electrical supply
and remove the analyser test probe from the
analysis test point and refit cap. Refit the air
chamber cover. Refit appliance casing.
NOTE
You should ensure that all radiators or heat
emitters are fully open during the above
procedures. This will ensure that the fan speed
(output) of the boiler is not compromised due to a
high flow temperature.
