Simultaneously, the module causes the ignitor to spark for up to 90 seconds to light the pilot flame. A flame sensor verifies that the pilot is lit by measuring the flow of microamps through the flame.

  • Page 26: Heating (Ignition) Failure

    1.16.1 Heating (Ignition) Failure Heating (ignition) failure occurs when the ignition module fails to sense a pilot flame within the 90-second time delay period and locks out. When this happens, the module sends 24 VAC through the SIB (smart interface board) alarm circuit to the controller.

  • Page 27: Improper Burner Function

    1.16.2 Improper Burner Function With problems in this category, the burner ignites but exhibits abnormal characteristics such as “popping,” fluctuating flame intensity, and flames shooting out of the flue. “Popping” indicates delayed ignition. In this condition, the main gas valve is opening but the burner is not immediately lighting.

  • Page 28: Improper Temperature Control

    Burners lighting on the left side only may be caused by a trailing pilot problem (four- and five-tube frypots) or improper burner manifold pressure. Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas pressure but may also be the result of variations in the kitchen atmosphere.

    air and decrease its efficiency. Also check the pre-filter. A plugged pre-filter (see Figure 34) can slow the flow of oil. Use the attached wrench to open (see Figure 35) and clean the pre-filter (see Figure 36). Ensure the pre-filter is tight and the O-ring is present to prevent air from entering the line and causing slow oil return.

    The clamps on the rubber boots that hold the drain tube sections together may loosen over time as the tubes expand and contract with heating and cooling during use. Also, the boot itself may be damaged. If the section of drain tube connected to the drain valve is removed for any reason, ensure that its rubber and clamps are in good condition and properly fitted around the drain tube when it is reinstalled.

  • Page 31: Troubleshooting The Gas Valve

    1.17.2 Troubleshooting the Gas Valve Prior to checking for problems associated with the gas valve, ensure that the unit is calling for heat. Also, for non-CE units, verify that the gas valve is in the ON position. The following processes will assist you in troubleshooting the gas valve and ruling it out as a probable cause: If 24 VAC is not present across gas valve main coil, the probable cause is the 24 VAC circuit.
