INSTALLATION

If the installation will use the supplied gas hose, be sure that the 1/2" to 3/4" gas line fitting is attached. Refer to the instructions in the gas hose package. One gas line connection method is shown in Figure 2-15; however, compliance with the applicable standards and regulations is mandatory.

Inlet and regulated gas pressures can be measured using a “U” tube manometer at the tap locations shown in Figures 2-15 and 2-16.

1.Checking the Gas Supply (Inlet) Pressure

a.With the main gas supply valve closed and the circuit breaker/fused disconnect in the OFF ("O") position, open the inlet pressure tap shown in Figure 2-16 and attach a manometer to the tap.

b.Depress the safety switches to allow the oven to operate.

c.Open the main gas supply valve. Switch the circuit breaker/ fused disconnect to the ON ("I") position.

d.Start the oven according the directions in the Operation section of this Manual. Adjust the temperature controller to the maximum setting (316°C).

e.Measure the supply (inlet) pressure.

f.Switch the oven off. Close the main gas supply valve, and switch the circuit breaker/fused disconnect to the OFF ("O") position. Remove the manometer, and close the inlet tap.

g.Compare the measured supply (inlet) pressure to the nominal pressures shown in Table 1-5 (in the Description section of this Manual).

If the supply pressure is lower or higher than the nominal pressure, the reason should be investigated and the gas supplier contacted.

For natural gas ovens, if the measured supply pressure is lower than 0.247psi, or higher than 0.363psi, contact the gas supplier. DO NOT OPERATE THE OVEN or adjust the oven controls.
