To attach the adapter, hold it in place and select the location for drilling a 1/8" diameter
hole (No. 30 drill) through the connecting overlap of the heater flue and the adapter
collar.

For an oblong horizontal flue, drill the first hole on either side of the top.
 For a round horizontal flue, drill the first hole in the top portion of the circle.
 For an oblong vertical flue, drill the first hole on either "end" of the side toward
the front of the heater.
 For a round vertical flue, drill the first hole on the portion of the circle toward the
front of the heater.
Insert a #10 sheetmetal screw. Drill two more holes -- for an oblong flue, drill a hole in
the opposite edge of the same side as the first hole, and one in the middle of the oppo-
site side; and for a round flue, space the three holes approximately equal distances
apart. Attach with sheetmetal screws.
3. Install the Venter Sub-Assembly -- The venter sub-assembly is assembled and
wired at the factory. It includes the blower, motor, capacitor, pressure switch, thermal
switch, and junction box. Select and follow the appropriate instructions.
Heater with a Horizontal Flue (FIGURE 4) -- Position the venter sub-assembly on the
flue adapter. The venter discharge outlet (vent connection) must be pointing in a direc-
tion from horizontal to vertical. Do not position the venter with the discharge outlet
(vent connection) in a direction below horizontal.

Heater with a Vertical (top ) Flue (FIGURE 5) -- Using sheetmetal screws, attach a
vent pipe elbow as shown in FIGURE 5. Position the venter sub-assembly on the vent
pipe elbow. The venter discharge outlet (vent connection) must be pointing in a direc-
tion from horizontal to vertical. Do not position the venter with the discharge outlet
(vent connection) in a direction below horizontal.
