Steffes 6140 - Manual (Page 14)

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.
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 will be difficult. Elements must be slid into the brick
core properly to ensure correct clearance between the terminal
connections and any surfaces within the system. Refer to the
required element connection clearance information in Figure 6.
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. Place bottom portion in first (Figure 5).
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 system using
the screws that were originally removed. 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 Remove the electrical panel cover and locate the element screw kit.
Step 6 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 20 inch lbs. Refer to Element Installation (Figure 6) for proper positioning.
Step 7 The brick core temperature sensor must be installed prior to putting the painted front panel in place.
