4. Installation

This heater requires hardwired installation by a qualified electrician. Ensure all local and national electrical codes are followed.

Installation Steps

  1. Locate Mounting Position: For effective air circulation, locate the heater at least 8 inches away from any walls and at least 6 feet away from the floor. Ensure the mounting surface (ceiling or wall) can support the heater's weight.
  2. Secure Mounting Bracket: Locate a ceiling joist or other firm support. Drill two 1/2" pilot holes off-center for the screws. Install the bracket with the included screws and washers. For single screw mounting, a larger lag screw may be required.
  3. Attach Heater to Bracket: Lift the heater, align the lower bracket holes with the threaded holes for the large knob-screws on both sides, and tighten.
  4. Adjust Louvers: Aim the heater horizontally or tilt by aligning the upper bracket holes with the threaded holes for the small knob-screws on both sides and tighten. Do not operate the heater with the front louvers closed.

  3. Connect Wires: Connect the L1 and L2 10 AWG copper wires to the power block terminals. Connect the 10 AWG ground wire to the designated ground terminal.
  4. Secure Connections: Torque all terminal screws and power block lugs tight with the required torque (35 in-lbs).
  5. Close Compartment: Reattach the bottom panel securely.
  6. Connect to Breaker: Connect the heater wiring to a properly sized current protection circuit breaker (e.g., 30A or 40A double-pole breaker for 5000W) in your service panel.
