The amulet has an inside edge that will cover the edge of the burner head. The air slots in the retention head must
not be blocked or obstructed by the amulet. If needed, trim a 45 degree chamfer on the inside of the amulet using a sharp
utility knife and maintain a 1/8" clearance to retention head air slots.
Once the amulet has been seated and trimmed, then install the burner into the boiler by carefully inserting the air tube
with amulet into the boiler opening while aligning the burner flange holes with the boiler studs. Install flat washers and
nuts onto the boiler studs and tighten all nuts evenly.
