OVEN BURNER PRESSURE
To check oven burner pressure, fit a pressure gauge to the front pressure test
point on the oven thermostatic gas control located behind the oven control
panel.
The oven burner pressures should be measured with the oven burner operating:
a) At maximum flow setting (refer oven maximum flow setting).
b) At minimum flow setting (refer oven minimum flow setting).
To check correct appliance operating pressure and/or supply pressures refer to
installation section.
OVEN MAXIMUM FLOW SETTING
The maximum flow setting on the oven control is factory set on the oven control
is factory set and sealed.
It should not be necessary to adjust at any stage. However, if a control is being
replaced and correct operation is required to be verified, the following check
should be made;
With the pilot burner lit, the oven burner pressure should be as listed below
when measured with the burner operating at maximum rate.(Set control knob to
position 7).
NATURAL (G20) -8.7 mbar ± 1.0 (3.5” WG ±0.2”)
PROPANE (G31) -35 mbar ± 1.0 (14” WG ±0.4”)
The maximum flow rate adjuster screw is located on the underside of the control
and should always be two (2) turns out and sealed.
DO NOT unscrew more than two turns.
OVEN MINIMUM FLOW SETTING
The minimum flow setting is important to ensure good temperature control of the
oven.
The minimum flow setting on the oven control is factory set and sealed.
It should not be necessary to adjust at any stage. However, if a control is being
replaced and correct operation is required to be verified, the following check
should be made;
With the pilot burner lit set oven control knob to position 7.
Measure the oven burner pressure as described above, then turn the control
knob back until just before the thermostat control snap-action turns the burner
off. The burner should now be operating at the minimum flow rate. The burner
pressure at this rate should be as follows.
NATURAL (G20) -3.7 mbar ± 0.5 (1.5” WG ±0.2”)
PROPANE (G31) -7.5 mbar ± 1.0 (3.0” WG ±0.2”)
