The burners are in the Burner Box that has a number from 72724 to 72731 on it. Locate the burner with the pilot mounting bracket welded to it, Figure 59. There will be two burners with pilot mounting brackets for 13 through 21 section boilers.

Attach the pilot(s) to the burner tube(s) using the allen head screw(s) provided, Figure 59. Remove the roll of 1/4" aluminum tubing and cut an 36" long piece from it, Figure 60. Ream and clean the tubing so it’s free from burrs.

Insert the tubing into the brass ferule on the pilot and tighten it with a wrench, Figure 61. Bend tubing to run parallel to burner tube exiting front of boiler. Avoid tight radius.
