LTD HEATER INSTALLATION
BE SURE POWER IS
DISCONNECTED AND LOCKED
OUT BEFORE INSTALLATION!
FAILURE TO DO SO MAY CAUSE
SERIOUS INJURY OR DEATH.
1. Place heater on the ground next
to the inlet of the centrifugal fan.
The LTD heater is designed to
mount upwind. Be sure airflow
decal is pointing towards the in-
let of the fan.
2. Bolt LTD mounting brackets to
each of the six holes in the
downstream angle ring of the
heater. Snug tighten bolts such
that they can still pivot with little
force applied. See chart for slots
to bolt through in bracket.

sary to remount the fan grill
