ADJUSTMENTS AND CHECKOUT

and associated flame safeguard controls.

Move the detector and sight pipe around to sight the flame at various positions and angles. Try to get a maximum steady meter reading. The signal must be above the minimum acceptable current/voltage listed in Table 6.

Measure the fIame signal for the pilot alone, the main burner flame alone, and both together (unless monitoring only the pilot flame when using an intermittent pilot, or only themain burner flame when using direct spark ignition). Also measure the flame signal at high and low firing rates and while modulating in between (as applicable). With the detec- tor in its final position, all required fhune signals must be steady and as specified in Table 6. If you cannot obtain the proper signals, refer to the Troubleshooting section.
