15) ATTACHING DRAFT INDUCER ASSEMBLY
1. Attach the draft inducer assembly and gasket to end of tube flange and secure with 1/4-20 locknuts. A flue restrictor
plate is loosely attached to the draft inducer weld studs. Make sure this remains in place while the draft inducer is being
attached to the heater body. NOTE: The draft inducer can be mounted in a vertical, a 45°, or a horizontal position. Refer
to the diagram on Multiple Hanging and Draft Inducer Positions (Section 16).
2. Disconnect the piece of SJO cable (if equipped) from the junction box and discard. This is used only on LTU series
heaters.
3. The 3/8" connector used to hold the SJO cable will remain to provide strain relief for field wiring of the control box and
the draft Inducer (refer to the Electrical Connections and Connection Wiring Diagram for wiring between the control box
and the draft Inducer in Section 22).
4. Place the starting collar on the draft inducer and secure with #8-32 screws and nuts.
5. If heater Is to be VENTED to the outside of the building, place the flue pipe directly onto the starting collar and secure with
#8 sheet metal screws. Terminate with an approved vent cap.
6. If the heater Is for (INVENTED use, place the exhaust hood (supplied as an accessory) on top of the starting collar. Secure
with #8 sheet metal screws. The exhaust hood must be mounted only in an upright position and directed toward the
reflector body.
7. Assemble the end reflector (packaged in the control draft inducer package) flush with the end of the main body reflector.
Secure by sliding speed clips onto the reflector edges. Evenly space the speed clips on the sides (one each side) and top
(two required) of the reflectors to provide a snug fit. Leave a 3" space between the end reflector and the draft inducer
