Gas Setup
A digital manometer that will read 0.10” WC (2.54 mmH2O, 0.249 mb) must be used to properly set all pressures. If the minimum pressure is not set correctly, the oven temperature will slowly rise in
Reading the Incoming Gas Pressure (Static)
1.Ensure the oven and all the equipment in the piping system are off (pilot lights are acceptable).
2.Remove the burner compartment cover and cooling fan tube (refer to page 1).
3.Remove the screw from the upper tap of the gas valve.
4.Attach the digital manometer to the upper tap of the gas valve (Figure 4). This tap will show the incoming pressure before the internal regulator of the gas valve.
5.The pressures must be no less than 6” W.C.
(152.4 mmH2O, 14.94 mb) and no more than 14” W.C. (350.6 mmH2O, 34.87 mb). Otherwise, severe damage to the equipment can occur.
6.Reattach the screw to the upper tap of the gas valve.
Reading the Gas Pressure at 100% Flame
1.Ensure the oven is on.
2.Select a cooking profile.
3.Remove the screw from the lower 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 lower tap of the gas valve (Figure 4).
5.Verify that the maximum operating pressure is
3.5” W.C. (88.9 mmH2O, 8.71 mb), unless operating I2L gas.
NOTE: I2L gas requires a pressure of 4” W.C. (101.6 mmH2O, 9.96 mb).
6.If not, use an 8mm nut driver to adjust the 8mm nut (Figure 4) until the manometer
reads 3.5” W.C. (88.9 mmH2O, 8.71 mb), unless operating I2L gas, as noted above (turn clockwise to increase the pressure, counter- clockwise to decrease the pressure).
7.Reattach the screw to the lower tap of the gas valve.
