Heating Element and Air Channel Installation

WARNING

HAZARDOUS VOLTAGE: Risk of electric shock. Can cause injury or death.

DO NOT remove the electrical panel cover while system is energized.
Position elements properly to avoid short circuiting them against metal surfaces.
Protect element lead wires from front panel screws and any field installed screws to avoid short circuit.

Insert Heating Elements

After all bricks are loaded, insert the heating elements between the brick layers, sliding them in until the element ends embed into the side cutouts of the brick cavity. Elements MUST be installed with the threaded screw tabs on the wire connection terminals pointing forward and down to ease the installation of the element-to-wiring harness. Note the required clearance (Figure 6.)

Install Front Air Channel

Install the front air channel by placing the bottom in first, with the air deflectors (arrow shaped pieces) facing inward. Refer to the Air Channel Placement (Figure 7) for proper placement and installation of the front air channel.

Lower Insulation into Place

Lower the insulation blankets back into position, one at a time. Carefully tuck the sides of this insulation into the edges, corners, and around the exposed portions of the heating elements to ensure maximum efficiency.

Reinstall Galvanized Front Panel

Reinstall the galvanized front panel by sliding the bottom of the panel inside the lower lip of the brick cavity and resting the top of the panel on the outside of the brick cavity. Secure it to the Comfort Plus Hydronic system using the screws that were originally removed.

Locate Hardware

Remove the painted front panel of the electrical compartment by removing the screws along the edges. Locate the installation hardware package that is shipped in this compartment.

Connect Element Harnesses

Carefully route the element wiring harnesses and connect them to the heating elements, using the screws provided in the hardware package. Connections should be made with the screw heads up and the threads pointing down. Element screws should be tightened to 30 inch lbs. Refer to Figure 6 for proper positioning.
