3.4 Start-Up Procedure (Applies to both the FBCR18 and FBKR18)
WARNING
Never operate this appliance with an empty cookpot. The cookpot must be filled
with water before lighting the burners.
CAUTION
If this is the first time the unit is being used after installation, refer to Section 3.5,
Boiling-Out the Cookpot.
Before turning the rethermalizer on, ensure that:
● the unit is connected to the water supply
● that the water supply is turned on
● that the unit is plugged into a 120VAC outlet
● that the electrical power supply to the rethermalizer is turned on
● that the gas supply to the rethermalizer is turned on.
1. Turn the gas valve to the ON position (see illustration below).

2. Press the computer Power switch. (On FBKR18 units, press either power switch.)
The AutoFill will, if necessary, add water until it reaches the upper water level sensor. The
AutoFill solenoid valve will cut off the water flow.
On FBKR18 Series units, a manual fill momentary switch (located on the component box cover
inside the door) may be pressed to override the solenoid valve and add water to the unit. Water is
added as long as the switch is pressed.
When the water level is above the lower water level sensor, the burners light for several seconds
then go out. A few seconds later they will light again. This cycle repeats until the water reaches
180°F (82°C). The burners then remain lit until the setpoint is reached. During the cycling,
FBCR18 Series units display CYCL. At 180°F (82°C), the display changes to °-Lo. FBKR18
Series units will display °-Lo. For either series, when the unit reaches setpoint, the display changes
to four dashes (- - - -), indicating the unit is ready for use.
Observe the burners through the burner viewing ports after 90 seconds of ignition. Look for a
bright orange-red glow. A blue flame or dark spots on a burner face indicate the air/gas mixture
requires adjustment. Refer to Chapter 4, Section 4.4, Clean Combustion Air Blower for adjustment
procedures.
