OPERATION

The booster heater is designed to deliver 180°F water, up to the gallons per minute and gallons per hour ratings specified in the table on page 4, depending on the incoming water temperature and Booster Heater model and its input BTU/Hr.

Provided the necessary power, water, gas, and vent connections are completed, a STAND ALONE unit is started by the activation of the On / Off Switch located on the front (Fig. 9). Provided the necessary power, water, gas, and vent connections are completed, the DISHWASHER ACTIVATED unit will be On when the dishwasher power switch is On. The Green indicator light is lit and the circulator pump turns on when power to the booster heater is On. The blower motor will start after about 6 seconds if the thermostat calls for heat.

Provided that the operating and safety controls including any vent switches are closed and that the thermostat is calling for heat, the Amber indicator light is lit. ☛ The blower turns on for about 10 seconds, providing clean air in the combustion chamber. Then the gas valve opens and the hot surface ignitor heats up for four seconds. With ignition, the flame sensor will detect that the burner flame has been established. If the burner flame is not sensed within a few seconds, the circuit repeats the process from ☛ for a total of three trial ignitions before the gas valve shuts off and requires reset.

To reset the ignition safety shutoff, momentarily turn the power switch off and then back on. If no power switch is present, turn the dishwasher off for one minute and then turn the dishwasher back on. When the water temperature exceeds the setting of the operating temperature control (thermostat board assembly), the burner will shut off until the next call for heat. The operating temperature control (thermostat board assembly) is factory set at 185°F.

On STAND ALONE units, the circulator pump will stay on as long as the On / Off Switch is on. On DISHWASHER ACTIVATED units, pump will stay on as long as the dishwasher is on. The blower is on when the thermostat is calling for heat and for 30 seconds after it is satisfied.
