TM 5-3895-374-24-2Direct Spark Oil Ignition Adjustments1.The ignitor assembly should be removed and cleanedregularly. The porcelain insulators should be kept cleanand must be replaced if cracked.2.The spark gap must be set in accordance with thedimensions noted. (Refer to Figs. 30, 31, 32). Ensurethat the distance between the electrodes and the nozzle(or diffuser) is greater than the spark gap.3.The electrodes should not extend closer than 1/8” to thespray angle of the nozzle to prevent carboning. A nozzlespray angle check card is available and may be used tocheck electrode position.4.The high tension wires and clips between the transformerand ignitor electrodes should be checked periodically fordeterioration.Figure 30Figure 31Figure 32Figure 33(page 3-984)
