When mounting the burner, the upper mounting plate (Fig. 8) must be removed to provide access to the area in front
of the combustion chamber. The combustion chamber can then be moved forward or backward slightly to allow for
adjustment in positioning the burner tube. A fiber insulating sleeve or amulet is provided on the burner tube of
specific Thermo Pride burners.(see Fig. 10). See Thermo Pride 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.
NOTE: The loose-fill insulation that is included in a brown paper bag should be lightly placed around the burner
tube between the front of the combustion chamber and the burner mounting plate. (DO NOT PACK THE
INSULATION DOWN). The loose-fill insulation should be placed in such a fashion that the surface of the
insulation is sloped from the top of the combustion chamber to the top of the lower mounting plate. The purpose of
the loose insulation is to help protect the burner tube, mounting plates and vestibule area from excessive
temperatures.
On the horizontal units, the loose-fill insulation will fall down around the side of the chamber (the chamber is on its
side in horizontal units). This presents no problem to the unit, as the amount of insulation under the side will be
minimal, but take care not to allow the insulation to fall into the open end of the chamber where it may burn and
blow around, possibly lodging in the burner.
NOTE: Do not place loose insulation around chamber sides and back.
