In order to avoid problems, check that the unit has been connected to the gas supply type and
voltage for which it was supplied. This can be done by examining the rating plate that lists the gas

PRESSURE SWITCH
The pressure switch is preset for proper operation from the factory and should not be adjusted until
it is determined to be the cause of an operating pressure deficiency.
Appliance malfunctions caused by pressure switch misadjustment are:
1. Pressure relief valve opening, especially on preheat from a cold start to 285 F (pressure
switch set too high.)
2. Burners being shut down prematurely by the pressure switch (pressure switch set is too low).
If adjustment of the pressure switch is required, it should be done as follows:
1. With the kettle empty and completely cold, turn kettle on and set thermostat between 7 - 8.
2. Pressure in kettle (read pressure gauge on front panel) should reach a maximum pressure of
40 psi and pressure relief valve should not open. Kettle pressure may rise 3 or 4 psi even after
burners shut down.
3. If relief valve did not open when kettle pressure reached 40 psi, the pressure switch setting is
satisfactory.
4. To obtain access to the pressure switch, remove the front panel.
5. To increase the pressure switch setting, turn white ribbed knob clockwise; to decrease turn
