TROUBLESHOOTING OPEN-TOP BURNERS

Each open-top burner should have a steady blue ame on each port of the burner. Propane burners may have a small

amount of yellow tipping, and may make a slight popping noise when turned off.

If the ame is rising up off of the ports, adjust the burner shutter so it is more closed. If the ame is long and yellow adjust

the burner shutter so it is more open.

Consult the following table and the owchart on this page.

Figure 6

Troubleshooting Open-Top Burners

TROUBLESHOOTING

Open-top burners are not working correctly.

Check that the burners are set level in their support brackets.

Check that each burner valve and orifice is in alignment with the corresponding burner.

Remove each burner and check that the venturi is clean and free of buildup and debris. Also check that the

orifice size is correct and that it is clean and free of buildup and debris.

Check that the burners are clean and that their ports are clear.

Remove the burner control knobs and carefully lower the control panel. CAUTION! Convection oven models

have wiring attached behind the panel.

Check the pressure of the gas supply with all the gas appliances connected to the supply turned fully on. The

inlet pressure (before entering the pressure regulator for the range) must be a minimum 7" W.C. for natural

gas, or a minimum 11" W.C. for propane but no more than 14” H

2O for either gas typ. Adjust the pressure

and/or capacity of the gas supply, if necessary.

Check the pressure of the gas manifold of the range (after the gas leaves the pressure regulator for the

range). See page 25.
