Reading the Gas Pressure at Minimum
Flame
1. Remove either the red or white wire
(Figure 4).
2. Attach the electric manometer to the lower
tap of the gas valve (Figure 4).
3. Verify that the minimum operating pressure is
0.10" W.C. (2.54 mmH
4. If not, use a 5mm nut driver to adjust the
5mm nut until the electric manometer reads
0.10" W.C. (2.54 mmH
clockwise to increase the pressure, counter-
clockwise to decrease the pressure).
5. Reconnect the wire you removed.
6. If adjustments were made, re-check 100%
flame pressure (see adjacent procedure).

Reading the Operating Gas Pressure

1. Ensure the oven is on.
2. Select a cooking profile (page 10).
3. Remove the screw from the upper tap of the
gas valve.
4. During warmup (both fan speeds are at 65%
and the oven is at 100% flame), attach the
manometer to the upper tap of the gas valve
(Figure 4).
5. Ensure that the pressure is no less than 6"
W.C. (152.4 mmH
more than 14" W.C. (350.6 mmH
34.87 mb).
6. Reattach the screw to the upper tap of the

Confirming Proper Closure of all Taps

Additional testing may be required - always
adhere to local gas codes and required methods of
leakage testing in the immediate location (refer to
the regulations in force in the country in which
the appliance is being installed). The prevailing
authority is the local code (or regulations).
1. Turn on the gas supply.
2. Spray all gas connections with a soap
solution.
-If growing soap bubbles are observed, a leak
-is present. Immediately shut off the gas
-supply.
-If no growth occurs, the connections are
-intact. Turn off the gas supply.
