HEATING ELEMENT AND AIR CHANNEL INSTALLATION
Step 1 After all brick are loaded, insert the heating elements be-
tween the brick layers, sliding them in until the element ends
embed into the side cutouts of the brick cavity.
3100 Series: The threaded screw tabs on the wire connec-
tion terminals should point forward.
4100 Series: The elements MUST be installed so their
threaded screw tabs on the wire connection terminals point
forward and down. If they are installed with the screw tabs
pointing upward, element-to-wiring harness connections
(Figure 7) will be difficult. Be sure the elements are slid into
the brick core properly to ensure correct clearance between
the terminal connections and any surfaces within the system
as shown in Figure 7.
Step 2 Install the front air channel with the air deflectors (arrow shaped pieces) facing inward and with the
narrow ends of the deflectors pointing up.
3100 Series: Place top portion in first.
4100 Series: Place bottom portion in first (see Figure 7.)
Step 3 Lower the insulation blankets back into position, one at a time. Carefully tuck the sides of the insulation into
the edges, corners, and around the exposed portions of the heating elements to ensure maximum efficiency.
Step 4 Reinstall the galvanized front panel and secure it to the Comfort Plus system using the screws that were
originally removed.
3100 Series: Slide the top of this panel inside the upper lip of the top painted panel. The bottom should
rest on the outside of the cavity and secure to the base with screws.
4100 Series: Slide the bottom of this panel inside the lower lip of the brick cavity. The top rests on the
outside of the cavity.
Step 5 Carefully route wiring harnesses and connect them to the heating elements, using screws provided in the
hardware package. Make connections with screw heads up and threads pointing down. Element screws
should be tightened to 14 inch lbs. Refer to Element Connection (Figure 7) for proper positioning.
Step 6 The painted front panel can now be installed on 3100 systems. If installing a 4100 system, the brick core
temperature sensor(s) must be installed prior to putting the painted front panel in place.

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.
