Step 1 After all brick 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. Ele-
ments 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.)
Step 2 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) and the
Parts Diagram (Page A.02) for proper placement and instal-
lation of the front air channel.
Step 3 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 element to ensure maximum efficiency.
Step 4 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.
Step 5 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.
Step 6 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.
