Modular heat units shipped to add heat onto existing blower only applications require field mechanical
and wiring installation.
1. Remove existing filter intake and lifting lugs from blower section intake side.

heater module.
5. Drill a hole in the discharge of the blower large
enough to insert the Maxitrol mixing tube and
discharge sensor (if provided). Install the Maxitrol mixing tube in the proper airflow direction. The
airflow direction is labeled on the Maxitrol mixing tube.
6. Wire the sensor as indicated on the supplied wiring schematic. Run all wiring within metal
conduit. Supply 120V AC to terminals 1 and N in the direct fired module.
