Step 6:
Replace in opposite order and test run heater.
Checking Operating Pressure:
This is done at the regulator located at the front RH corner of the appliance.
This is best done before the fascia panels have been fitted to avoid fascia damage. Pressure
test points are available for both inlet and operating test pressure (as shown below).
1) Remove inlet pressure test point screw and attach manometer tube.
2) Run the heater on full (all three burners running) and measure inlet pressure. If
pressure does not fall within the maximum or minimum pressures listed on the table
below then reassess installation pipe size or upstream regulator settings. Replace inlet
test point screw.
3) Remove the operating pressure test point screw. Connect manometer tube and
measure pressure with heater running on full (all three burners running).
4) The heater regulator pressure has been factory set to 0.87KPa for Natural Gas
heaters and 2.30Kpa for LPG heaters. Please check that the operating pressure is
exactly as listed and if not, adjust screw in centre of regulator until pressure is correct.
5) Replace operating test point screw and leak test both test points.
