Procedure

1.Turn on pilot gas supply, light pilot, and check pilot tubing connections for leakage. With main burner in operation, paint tubing connections with a rich

soap and water solution. Bubbles indicate a gas leak.

2.Adjust pilot to obtain a normal flame enveloping 3/8 to 1/2 inch [9.5 to 12.5 mm] of the thermocou- ple or generator tip.

3.Place system in operation, and:

a.Check for satisfactory ignition of main burner.

b.Make certain the pilotstat "holds in", and that shutdown occurs within 2-1/2 minutes after the pilot flame is extinguished.

c.Observe operation for at least three cycles to be sure the system is functioning normally.
