2-2 This equipment is manufactured to use the type of gas specified on the rating plate attached to the door. Connect equipment stamped “NAT” only to na tural gas and that stam ped “PRO” only to LP (Propane) gas. Installation shall be made with a gas connector th at com plies with national and local codes.
2-3 After the unit has been positioned in the area wher e it will be used, ensure the following has been accomplished before connecting the unit to the gas supply: 1. Adequate means must be provided to lim it the movem ent of this equipment without depending upon the gas line connections.
2-4 2.4 Connecting to the Gas Supply GAS CONNECTIONS AND PIPE SIZES The size of the gas supply pipe is very important. If the pipe is too sm all, the gas pressure at the burner manifold will be low. This will cause slow recovery and delayed ignition. The incom ing gas supply line should be a minimum of 1½ inches (38mm) ID.
2-5 WARNING “Dry-firing” this equipment will cause damage to the cookpot. Always ensure that the cookpot is filled with w ater before firing your unit. 4. It is suggested that the burner manifold pressu re be checked at this tim e by the local gas com- pany or an authorized service agent.
3-1 FBR18 & FBRA18 SERIES GAS RETHERMALIZERS CHAPTER 3: OPERATING INSTRUCTIONS 3.1 Introduction Mechanically, the FBR18 and FBRA18 rethermalizer s are virtually identical, the only difference being that the FBRA18 units have an automatic filli ng (AutoFill) feature.

5-1 FBR18 & FBRA18 SERIES GAS RETHERMALIZERS CHAPTER 5: OPERATOR TROUBLESHOOTING 5.1 Introduction This chapter provides an easy reference guide to the more com mon problems that m ay occur during the operation of your equipment.
5-2 5.2 Troubleshooting Guides COOKPOT DID NOT FILL WHEN UNIT WAS TURNED ON. WATER SUPPLY TO UNIT VERIFIED TO BE ON. Did anything appear in controller display when unit was turned on? Open control panel by removing screws in each upper corner.
5-3 WATER DID NOT SHUT OFF WHEN COOKPOT WAS FULL. Use bottlebrush to clean water level sensors. Did water stop? Problem resolved. Add 1/8 cup of salt to water in cookpot and stir. Did water stop? Mineral content of water is insufficient for water sensor to detect it.
5-4 WATER NOT HEATING. AUTOFILL (IF INSTALLED) WORKED PROPERLY. Press the Temperature Check button twice to display setpoint. Has the correct setpoint been programmed? Did burners light? Did water reach setpoint temperature? Problem resolved. Insert a good grade thermometer into cookpot with tip near temperature probe and wait two minutes.
5-5 BURNERS DO NOT LIGHT. Verify that correct setpoint has been programmed, that main gas supply valve is open, and that equipment gas valve is set to ON. Press ON/OFF button. Did burners light? Problem resolved. Use bottlebrush to clean low water sensor.
5-6 5.3 Replacing the Controller or Controller Wiring Harness 1. Disconnect the rethermalizer from the electrical supply. 2. Remove the two screws in the upper corners of the control panel and swing the panel open from the top, allowing it to rest on its hinge tabs.

6-2 guished), current to the ignition module is cut, pr eventing the main valve from opening, and the igni- tion module “locks out” until the power switch is turned off and then back on.
6-3 The relays in earlier design boards are soldered on and cannot be replaced. Later design boards fea- ture replaceable plug-in relays. In earlier designs boards, a heat relay (K2) switches 24VAC to the ignition and gas valve circuits when the controller h eat logic circuit calls for heat.
6-4 the upper water level sensor causes the water relay (K 2) to open. This cuts power to the water sole- noid valve, which closes, cutting off water flow into the cookpot. 6.2 Accessing the Rethermalizer for Servicing DANGER Moving a rethermalizer filled with hot w ate r may cause spilling or splattering of the hot water.
6-5 the unit exceeds that temperature, the burner will stay on until the setpoint is reached. Check the reading when the burner has been on continuously for at least one minute. 6.6 Replacing Components 6.6.1 Replacing the Controller or Controller Wiring Harness Refer to Chapter 5, Section 5.
6-6 7. Remove the two upper screws securing the com ponent box to the rethermalizer. Rotate the box forward and outward to expose the 12-pin connect or on the rear of the interface board, and un- plug it from the board.
6-7 5. Reconnect the ignitor wire, flame sensor wire, and gas enrichment tube. 6.6.6 Replacing the Combustion Air Blow er Refer to Chapter 4, Section 4.4, Clean Combustion Air Blower, for instructions on rem oving and reinstalling the combustion air blower.
6-8 4. Remove the four screws from the blower stabiliz ing bracket attached to the blower assem bly and to each burner. Remove the stabilizing bracket from the unit. 5. Rem ove the screw securing the blower support bracket to the cookpot assembly and lower the blower assembly out of the way.
6-9 knowledge of possible problems, and the probable cau ses of each. W ith this knowledge, the techni- cian should be able to isolate and correct any problem encountered. Problems that are likely to be encountered can be grouped into five broad categories: 1.
6-10 tion failure situation may be encountered in which all com ponents appear to be serviceable and the microamp reading is within specification, but the unit nevertheless goes into ignition failure during operation. The probable cause in this case is an inte rmittent failure of an i gnition module.
6-11 If popping is consistent during all hours of operation, the most likely cause is an insufficient air sup- ply. Check for “negative pressure” conditions in the kitchen area. If air is flowing into the kitchen area, this indicates that more air is being exhaus ted than is being replenished, and the burners may be starved for air.
6-12 6.7.3 Improper Temperature Control Temperature control is a function of several inte rrelated com ponents, each of which must operate correctly. The principle component is the temper ature probe. Other components include the inter- face board, the water level sensors (on FBRA18 units ), the controller, and the ignition module.
6-13 6.8.1 Troubleshooting the Gas Valve NOTE: All voltage measurements must be made within 4 seconds of unit calling for heat. If unit does not fire within 4 seconds, ignition modules will lock out and controller must be turned off then back on to reset.
6-14 6.8.2 Troubleshooting the 24 VAC Circuit in FBR18 Units NOTE: All voltage measurements must be made within 4 seconds of unit calling for heat. If unit does not fire within 4 seconds, ignition modules will lock out and controller must be turned off then back on to reset.
