LTS SERIES - ATTACHING DRAFT INDUCER ASSEMBLY

1. Attach the draft inducer assembly and gasket to end of the draft inducer flange and secure with 1/4-20
locknuts. A flue restrictor plate is attached to the draft inducer weld studs. DO NOT DISCARD RESTRICTOR
PLATE and 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 45º, or a horizontal position. Refer to Section 13.0).
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 16.0).
4. If the heater is to be VENTED to the outside of the building, place the starting collar on the outlet of the draft
inducer and secure with the #8-32 screws and nuts. Place the flue pipe directly onto the starting collar,
secure with the #8 sheet metal screws, and terminate with an approved vent cap.
5. If the heater is for UNVENTED use, place the exhaust hood (supplied as an accessory) directly onto the outlet
of the draft inducer (starting collar is not necessary for unvented use). Secure with the #8 sheet metal
screws. The exhaust hood must be mounted only in an upright position and directed toward the reflector
body.
6. Assemble the end reflector flush with the end of the main 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 assembly.
