Operation continued

This manual reset button can be located on the ignitor board or remotely on a control panel. (Consult factory for remove mounting agency approvals). Should the flame not be established during the trial for ignition period, the system will lock-out. Should flame-out occur any time during the duty cycle, the system will retry for ignition, one time, and then lock-out. The manual reset button will then trip within several seconds. After 5 second, depress the reset button to reset the control module.

Flame Sensing

The Series 05-14 ignitor is designed to operate with a single electrode assembly, which provides the spark and senses the presence of flame. See Figure 3 Aor B. Remote sensing models, however, allow for the flame sensing function to be separated from the spark function and located remotely. See Figure 3C or D. Utilization of remote sensing insures flame propagation across and entire burner pack.

Electrode Application

(Burner Manufacturer only)

1.Manually ignite burner flame to observe flame characteristics.

2.Temporarily mount electrode directly over burner parts in blue part of flame pattern. Electrode tips should be 1/4 to 1/2-inch above parts. Mount electrodes so that both tips are immersed approximately 1/2-inch into the flame with 1/8-inch spark gap directly over a port. See Figure 1.

Figure 1

3.Connect the electrode lead wires to the control module. See Figure 3. Make

certain that the remaining system wiring is complete.

4.With the gas supply m;anually shut off, cycle the thermostat to operate the control module. Insure that steady sparking occurs at electrode tips. Sparking should not occur elsewhere.

5.Cycle thermostat to OFF position or depress reset button and manually restore gas supply.

6.Cycle thermostat on ON position noting that sparking occurs immediately and that the flame is established within a period of no more than four seconds. Once the flame is established, sparking will cease.

7.If ignition is achieved within four seconds and sparking terminates immediately after flame is established, you have a functionaaly sound installation. However, should these requisites not be met, consult the "System Checks" section on page 4 for

remedial recommendations.

NOTE: Electrode assemblies are presision components and should not be adjusted or disassembled. Electrodes should have a gap spacing of 0.125"=0.031". If this spacing is not correct, return the electrode assembly to the factory for replacement. Electrodes are NOT field adjustable.
