3-5 4. Remove the wire and blow through the tube to ensure it is clear. 5. Reinstall the tube and bend it so that the opening is pointing downward. 3.4 Checking the Burner Manifold Gas Pressure DANGER Frymaster recommends that ONLY qualified service personnel perform this task. 1. On non-CE fryers, ensure that the gas valve knob is in the OFF position. HoneywellON OFF 2. Remove the pressure tap plug from the gas valve assembly. Typical Non-CE Valve Assembly Typical CE Valve Assembly Pressure Tap Plug 2. Insert the fitting for a gas pressure-measuring device into the pressure tap hole. 3. On non-CE fryers only, place the gas valve in the ON position. 4. Place the fryer power switch in the ON position. When the burner has lit and burned steadily for at least one minute, compare the gas pressure reading to the pressure for the corresponding gas in the appropriate table found on the following page. 3-6 CE Standard Burner Manifold Gas Pressures for Fryers M anufactured After April 1999 Pressure (m bar) Gas Natural Gas Lacq (G20) at 20 mbar Natural Gas Gronique * (G25) at 25 mbar Natural Gas Gronique (G25) at 20 mbar Butane/Propane (G30) at 28/30 or 50 mbar Propane (G31) at 37 or 50 mbar Single Dual Vat Vat 7 7 10 10 10 10 17 17 20 20 * Belgian G25 = 7.0 mbar (single or dual) CE Standard Burner Manifold Gas Pressures for Fryers Manufactured Through April 1999 Pressure (mbar) Single Dual Gas Vat Vat Natural Gas Lacq (G20) under 20 mbar 7 6.5 Natural Gas Gronique * (G25) under 25 mbar 10 9 Natural Gas Gronique (G25) under 20 mbar 10 9 Propane (G31) under 37 or 50 mbar 20.2 18.5 * Belgian G25 = 7.0 mbar (single) or 6.5 (dual) Non-CE Standard Burner M anifold G as Pressures G as P ressure 3" W .C.

Remove the fitting from the pressure tap hole and reinstall the pressure tap plug. 3.5 Measuring Flame Current When the burner flame is properly adjusted, it will produce a current between 2.5 .A and 3.5 .A. Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing wire on the ignitor. This is accomplished as follows: 1. Place the fryer power switch in the OFF position. 2. Disconnect the white sensing wire from one of the burner ignitors and connect it to the positive lead of the meter. Connect the negative lead of the meter to the terminal from which the sensing wire was removed. 3. Place the fryer power switch in the ON position to light the burners. After the frypot temperature reaches 200°F (93°C), wait at least one minute before checking the reading. NOTE: The closer the unit is to normal operating temperature, the more accurate the reading will be. 3.6 Replacing Fryer Components 3.6.1 Replacing the Controller or the Controller Wiring Harness 1. Disconnect the fryer 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. 3. Disconnect the wiring harness from the back of the controller and, if replacing the harness, disconnect it from the interface board. 4. Disconnect the ground wire from the controller, and remove the controller by lifting it from the hinge slots in the control panel frame. 5. Reverse the procedure to install a new controller or wiring harness. 3.6.2 Replacing the Temperature Probe or High-Limit Thermostat 1. Disconnect the fryer from the electrical supply. 2. Drain cooking oil below the level of the probe or thermostat. 3. Remove the screws from the upper corners of the control panel and swing the panel open from the top, allowing it to rest on its hinge tabs. 4. Unplug the controller wiring harness from the back of the controller. 5. Disconnect the ground wire from the controller, and remove the controller by lifting it from the hinge slots in the control panel frame. 6. Remove the screws securing the topcap to the fryer and lift the topcap up and off the fryer. 7. Disconnect the ignition cables from the ignitors by grasping the boots and gently pulling toward you. 8. Remove the screws securing the control panel frame in place and remove the frame. 9. Remove the component box mounting screws and rotate the top of the component box out of the cabinet. Carefully pull it out far enough to disconnect the wiring harness plug(s) from the back of the box. Remove the box and set it aside. 10. On CE fryers with a blower shield assembly installed, remove the screws securing the shield in place and remove it from the cabinet. 11. Make a note of the location of the existing wires. Using a pin-pusher, disconnect the temperature probe wires (or high-limit thermostat wires) from the connector plug. 12. Unscrew and remove the tempe...
