Installation Instructions
WARNING
Before proceeding further with the installation of this heater, turn off the power and
lock to the supply line for the heater at the
main service box.
Remove the heater from the box and check for any
damage. Verify that the factory installed options are
correct for the application. Remove and set aside the
grill.
Select power supply wire type and size to comply
with local and national electric codes using heater
rating given in table. Connect wire to heater as
shown in wiring diagram attached to cover. Remove
one of the knockouts from back of unit. Secure
power supply cable with clamps (or run in conduit,
if required by local codes). Also run the wiring for a
remote thermostat, if required. Connect grounding
conductor to the green screw.
Fasten the heater to the wall with #10 screws, as
shown in the mounting diagrams. On recess models,
be sure to leave enough clearance to install the grill.
Replace the grill. Test the heater for proper operation.
