When mounting the burner, the mounting plate (Fig. 11) must be removed to provide access to the area
in front of the combustion chamber. A fiber insulating sleeve or amulet is provided on the burner tube of
specific burners.(see Fig. 12). See burner application chart for type of insulator. Do not allow the burner
tube or end cone to physically touch or protrude into the chamber, as excess heat transfer could result in
destruction of the tube, end cone or both. The burner tube/end cone is properly positioned, when the end
is ¼ inch back from the inside surface of the combustion chamber wall.
DO NOT CHANGE POSITION OF THE CHAMBER!
