F. BURNER INSTALLATION:
NOTE: The burner is factory installed on this furnace.
NOTICE: Remove all cardboard packing from around chamber before installing burner.
The oil burner will mount on three stud mounting bolts on the lower mounting plate covering the opening in the front
of the heat exchanger. The end of the burner tube should be inserted no further than 1/4 inch back from the inside
surface of the combustion chamber. A distance further than 1/4 inch back from the inside chamber wall may cause
impingement and sooting. This unit is equipped with a chamber retainer (refer to Fig.4). This retainer secures the
chamber during shipping and helps to maintain insertion depth. DO NOT remove this retainer when installing
burner.

When mounting the burner, the mounting plate (Fig. 4) 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.
5). 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.
