OPERATING SEQUENCE

The booster heater is designed to produce 180-190 degree sanitizing rinse water for commercial dishwashing machines. Specific performance depends upon the exact water flow and supply water temperature. (See table)

After the necessary power, water, gas and vent connections are completed correctly and all air is purged from gas and water piping, the unit is started by turning on the power switch located on the top, front of the left side panel. The combustion air fan will start and run continuously and the digital temperature display will light, showing the water temperature in the accumulator tank. If the tank temperature sensor detects water temperature below the set point, it will turn on the internal circulating pump, prove water flow, combustion air flow and hi-limit compliance and activate the hot surface igniter. Following a 3 second warm up for the igniter, the gas valve opens and the burner ignites. If the burner flame is not proved within a few seconds, the gas valve automatically closes. This cycle will repeat 3 times. If ignition/flame is not proved the control will go into automatic lock-out, requiring a re-set. Re-set is accomplished by turning power switch to ‘off’ for 10 seconds and then turning back on. When the tank water temperature exceeds the thermostat set point, the burner will shut off until the next call for heat.

The internal circulating pump will operate whenever the thermostat is calling for heat. The combustion air blower operates continuously whenever the ‘on-off’ switch is on.

The operating temperature control is factory-set and is not to be user-adjusted. If temperature rise is not satisfactory, call your service agency and/or call the factory.
