- Turn on an adjacent hot water draw off, the
appliance will now light and the fan will
change to high speed.
- Check burner setting pressure at test point A
see Section 1.3 technical data (see fig. 15).
- If the burner setting pressure is not correct,
check that the pressure at the gas service
cock, test point B is 20 mbar (8. in. w.g.)
with the appliance operating. If the inlet
pressure is not correct, check for any pos-
sible blockage or restriction in the pipe-
work to the appliance. If the inlet supply
pressure cannot be corrected contact your
local gas region. The heat input to the
appliance is pre-set and non-ajustable.
