Text Box: Sherwood Industries Ltd. ENVIRO PAGE 1 Flowchart: Alternate Process: IF IT FAILS, replace piezo ignitor. Flowchart: Alternate Process: Retighten hex nut on back of the ignitor and make sure bracket is secure on the valve. Flowchart: Alternate Process: Replace electrode. Flowchart: Alternate Process: IF IT DOES, replace electrode. Flowchart: Alternate Process: Replace with only manufactures parts Flowchart: Alternate Process: Make sure piezo ignitor is working properly. Place a screwdriver next to ignitor, and press ignitor. If it sparks, OK. Flowchart: Alternate Process: Make sure that wires are not broken, frayed and that all connections are tight at both the piezo ignitor and electrode. Flowchart: Alternate Process: Make sure that ceramic on the electrode is not broken. Carefully try to spin the porcelain. Flowchart: Alternate Process: Make sure a 1/8” (3.175mm) gap is maintained between electrode and pilot hood. SEE PAGE 2 FIGURE 1. Flowchart: Alternate Process: Make sure the piezo ignitor is not loose.

ENVIRO PAGE 3 Flowchart: Alternate Process: Clean the pilot injector if necessary. Flowchart: Alternate Process: Wait 60 seconds for the safety to reset itself. Flowchart: Alternate Process: Use a match to see if air or gas comes from the pilot assembly. Flowchart: Alternate Process: Turn service valve to the “ON” position. Flowchart: Alternate Process: Correct if necessary. Flowchart: Alternate Process: Correct if necessary, test for gas leaks in an approved manner. Flowchart: Alternate Process: Make sure pilot injector is not clogged. Flowchart: Alternate Process: Make sure that the valve has not reset itself. (All valves have an interlock safety device.) Flowchart: Alternate Process: Test to make sure there is no air in the gas line. SEE PAGE 4 FIGURE 3. Flowchart: Alternate Process: Make sure the appliance service valve is in the “ON” position. SEE PAGE 4 FIGURE 3. Flowchart: Alternate Process: Make sure that the gas is “ON” (NG) Natural gas and (LP) Propane tanks are full. Flowchart: Alternate Process: Make sure all gas lines have been connected with no leaks. Flowchart: Terminator: B) PIEZO IGNITOR OK BUT PILOT WILL STILL NOT LIGHT Text Box: Sherwood Industries Ltd. ENVIRO PAGE 4 Text Box: EXPLODED VIEW S.I.T PILOT ASSEMBLY Text Box: PILOT HEAD THERMOPILE PILOT INJECTOR SPARK ELECTRODE THERMOCOUPLE Text Box: To remove pilot injector: Remove the two screws that hold the pilot assembly to the burner control assembly. Lift the assembly straight up being careful not to damage any components. Using a 10 mm wrench undo the securing nut on pilot tubing and pull tubing down to access injector. Being careful not to damage the ceramic spark electrode. Replace the injector and reinstall the pilot tubing, always to perform a gas leak test before lighting the pilot assembly. The number on the side of the injector will determine the size. This number is in millimeters.
