P*LBX20F19001 ASSEMBLY NOTES
The P*LBX20F19001 oil-fired furnace is shipped in two
pieces; the furnace section and the blower section. These
two sections must be assembled together at the installation
site.
1. Remove the crating and packaging materials from each
section. Remove the flue pipe flange gasket packed with
the furnace section. The flue pipe gasket will be lying
loose on the floor of the furnace section.
2. Remove the shipping brace from the furnace section
flue pipe flange and cabinet. Remove and save all of the
screws from the flue pipe flange, and the ten screws
from the rear edges of the furnace section cabinet, (5
per side). The screws will be re-used.
3. Place the furnace section and blower section in close
proximity. Route the wiring harness from the base of the
furnace section through the plastic grommet in the
blower section blower division panel.
4. Position and align the flue pipe flange gasket between
the furnace section and blower section flue pipe flanges,
and hold it in place with a pair of awls or similar tool.
5. Begin fastening the flue pipe flanges together from
inside the blower section to the furnace section with the
six 1/4-20 x 3/4 inch screws saved from the removal of
the shipping brace. Start each screw carefully so as not
to damage the flue pipe flange gasket. After all six
screws have been started, and proper gasket alignment
has been confirmed, tighten all six screws evenly.
6. Align the screw holes in the blower section blower
division panel with the screw holes in the furnace
section cabinet rear edge, from which the ten screws
were removed. The screws are started from the inside
of the blower section to the furnace section. Tighten all
ten screws evenly.
7. In a similar manner, start four of the extra screws
removed and saved from the furnace section flue pipe
flange into the screw holes along the top of the two
furnace sections.
8. Remove the blower motor electric wiring cover plate.
Connect the black lead from the wiring harness to motor
terminal L1, the white lead to motor terminal L2, and the
green lead to the motor casing ground terminal. Position
the wires in the motor casing indentations and re-install
the blower motor electric wiring cover plate.
