7. Remove (8) M14 Door Fixation Screws (12mm Allen) from the perimeter of burner door that are
used to secure the door to the exchanger. Once all screws are removed, the door should be
free to slide out of the front of the cabinet.
8. Remove the pin located to the left of the door that locks the hinge in place. Once the pin is
removed, the door will be free to rotate about the hinge, providing better access to the inside of
the heat exchanger. BE CAREFUL NOT TO DAMAGE THE EQUIPMENT OR THE BURNER,
WHICH ARE MOUNTED TO THE DOOR, WHEN ROTATING ON THE HINGE.
9. Swing open the burner door/heat exchanger door to provide access to the inside of the heat
exchanger. The burner does not need to be removed. Patterson-Kelley does not recommend
removing the burner, though it may be removed to provide better access for cleaning the
exchanger.
