the pilot flame 2. Loose spark wire; loose igniter nut. 3. Piezo-electric igniter does not generate a spark. 2. Check spark wire connection at the igniter nut and make sure the connection is tight. 3. Replace igniter mechanism (portion with pushbutton). Pilot flame does not stay lighted. 1. Dirty/sooty pilot burner. 2. Low gas supply pressure [less than 6” W.C. for natural gas; (11” W.C. for propane) when all other gas-powered equipment is operating]. 3. Pilot flame too small to heat the thermocouple. 4. Pilot flame ‘wavering’ (being blown about by a draft). 5. Improper thermocouple output voltage (must be at least 10 millivolts, measured at the thermocouple junction block). 6. High-limit thermostat problem has shut off the gas. 1. Clean the pilot burner. Perform the Lighting Procedure. 2. Measure the gas supply pressure. Contact your local gas supplier to obtain adequate gas supply pressure. 3. Adjust the pilot valve (part of the gas control valve) to increase the flame size: Unscrew and retain the slotted threaded cover; turn the pilot valve adjustment screw two turns counterclockwise; reinstall the threaded cover. 4. Block or redirect the draft, to keep the flame burning steadily. 5. Replace the thermocouple. 6. Check for, and repair, any damaged high-limit thermostat wiring. [For model 14GSU fryer ONLY: Press the reset push- button on the high-limit thermostat control. Perform the Lighting Procedure, to check whether the pilot flame lights. If the pilot flame stays lit, the high- limit thermostat has failed and must be replaced. ] . . . &" . ). Pilot flame does not stay lighted. (Continued) Pilot flame goes out repeatedly. . 6. High-limit thermostat problem has shut off the gas. (Continued) 7. Gas control valve has failed. 1. Low gas supply pressure [less than 6” W.C. for natural gas; (11” W.C. for propane) when all other gas-powered kitchen equipment is operating]. 2. Loose thermocouple or high-limit thermostat connection(s) on gas control valve. 3. Pilot flame does not continuously touch the thermocouple because of excessive air flow around the pilot burner assembly. 4. High-limit thermostat problem has shut off the gas. &( 1. Measure the gas supply pressure. Contact your local gas supplier to obtain adequate gas supply pressure. 2. Check and tighten the connections. 3. Block the excessive air flow to make the pilot flame contact the thermocouple. 4. Check for, and repair, any damaged high-limit thermostat wiring. [For model 14GSU fryer ONLY: Press the reset push- button on the high-limit thermostat control. Perform the Lighting Procedure, to check whether the pilot flame lights. If the pilot flame stays lit, the high- limit thermostat has failed and must be replaced. ] CAUTION: DO NOT return the fryer to normal operation with its high-limit thermostat bypassed/disconnected. ! 6. (Continued) For model 14GS, MX-14EG, and MX14-EGU fryers ONLY: Test the high-limit thermostat by disconnecting the thermocouple at the gas control valve. Then, disconnect the red wires to the high-limit thermostat from the gas control valve. Reconnect the thermocouple; next, perform the Lighting Procedure, to check whether the pilot flame lights. If the pilot flame stays lit, the high-limit thermostat has failed and must be replaced. 7. Replace the gas control valve. . . . &" . ). Pilot flame goes out repeatedly. (Continued) Main burners do not ignite. . &(. 4. High-limit thermostat problem has shut off the gas. (Continued) 1. Gas control valve knob set to OFF or PILOT. 2. Low gas supply pressure [less than 6” W.C. for natural gas; (11” W.C. for propane) when all other gas-powered kitchen equipment is operating]. 3. Pilot burner problem. 4. Thermostat control set below the temperature of the liquid shortening in the kettle. 5. Gas control valve has failed. 4. (Continued) For model 14GS, MX-14EG, and MX14-EGU fryers ONLY: Test the high-limit thermostat by disconnecting the thermocouple at the gas control valve. Then, disconnect the red wires to the high-limit thermostat from the gas control valve. Reconnect the thermocouple; next, perform the Lighting Procedure, to check whether the pilot flame lights. If the pilot flame stays lit, the high-limit thermostat has failed and must be replaced. ! CAUTION: DO NOT return the fryer to normal operation with its high-limit thermostat bypassed/disconnected. 1. Perform the normal Lighting Procedure. Turn the gas control valveknob to ON to light the main burners. If the burners do not light, the gas control valve has failed and must be replaced. 2. Measure the gas supply pressure. Contact your local gas supplier to obtain adequate gas supply pressure. 3. Refer to the preceding Pilot Burner problems and use the correct remedy. 4. Increase the thermostat setting until the burners light. If this setting is greater than the desired temperature, reset the thermostat to the desired setting and allow the shortening to cool to the desired temperature. 5. Replace the gas control valve. ...
