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 

 signal for the pilot alone, the main

burner flame alone, and both together (unless monitoring

only the pilot 

 when using an intermittent pilot, or only

 burner 

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 

 signals must be

steady and as specified in Table 6. If you cannot obtain the

proper signals, refer to the Troubleshooting section.
