Page 10: National Code Requirements
One of the most important considerations of efficient operation is ventilation. Make sure the equip- ment is installed so that products of combustion are removed efficiently, and that the kitchen ventila- tion system does not produce drafts that interfere with proper burner operation. The equipment flue opening must not be placed close to the intake of the exhaust fan, and the flue must never be extended in a “chimney”... -

Frymaster computers have been tested and found to comply with the limits for a Class A digi- tal device, pursuant to Part 15 of the FCC rules. While these devices are verified as Class A devices, they have been shown to meet the Class B limits. - Page 12 2. The rethermalizer must be stabilized by installing restraining chains on units equipped with casters or anchor straps on units equipped with legs. Follow the instructions shipped with the casters/legs to properly install the chains or straps. 3. Level rethermalizers equipped with legs by screwing out the legs approximately 1 inch then adjusting them so that the rethermalizer is level.

Page 22: Start-Up Procedure
Start-Up Procedure (Applies to both the FBCR18 and FBKR18) Never operate this appliance with an empty cookpot. The cookpot must be filled with water before lighting the burners. If this is the first time the unit is being used after installation, refer to Section 3.5, Boiling-Out the Cookpot. -
Page 23: Shutting The Rethermalizer Down
Boiling-Out the Cookpot Never leave the appliance unattended during the boil-out process. If the boil-out so- lution boils over, turn the appliance off immediately and let the solution cool for a few minutes before resuming the process. To lessen the chance of boil over, turn the appliance’s gas valve knob to the PILOT position occasionally. -

Page 42: Ignition Failures
Problems that are likely to be encountered can be grouped into five broad categories: 1. Ignition failures 2. Improper burner functioning 3. Improper temperature control 4. Computer-related problems 5. Autofill System problems. The probable causes of each category are discussed in the following sections. Troubleshooting Guides (decision trees) is also included at the end of the chapter to assist in identifying some of the more common problems. -

during operation. The probable cause in this case is an intermittent failure of an ignition module. When the unit is opened up for troubleshooting, the module cools down enough to operate correctly, but when the unit is again closed up and placed back into service, the module heats up and fails. PROBLEMS RELATED TO THE GAS VALVE If the problem is not in the 24 VAC circuit, it is most likely in the gas valve itself, but before replacing the gas valve, refer to the troubleshooting guide... - Page 44 If popping is consistent during all hours of operation, the most likely cause is an insufficient air supply. Check for “negative pressure” conditions in the kitchen area. If air is flowing into the kitchen area, this indicates that more air is being exhausted than is being replenished, and the burners may be starved for air.

Page 45: Improper Temperature Control
6.7.3 Improper Temperature Control Temperature control is a function of several interrelated components, each of which must operate correctly. The principle component is the temperature probe. Other components include the interface board, the water level sensors, the computer, and the ignition module. Whatever the cause, the symptom is failure of the unit to attain or maintain setpoint temperature. -
