Field Wiring
Step 1 After establishing placement of the heater, mount a field
connection junction box in a location where heater-to-field
wiring connections can be made easily. The junction box can be
located beside the heater, behind the heater, or mounted in the
floor below the heater. Steffes Corporation recommends a steel
junction box to provide protection against overheating.
The junction box MUST remain accessible for future
service to the heater and MUST be sized in accordance
with all applicable electrical codes and regulations.
Step 2 Route the proper size and type of wiring from the breaker panel
to the field connection junction box.
Step 3 Connect the field wiring to the wiring harness (umbilical cord) of the heater inside the junction box.
Step 4 Remove the orange breaker panel label from the mounting hardware package. This label MUST be
applied in the electrical service (breaker) panel and marked accordingly to identify the branch circuits
feeding the room heating unit.
