DISASSEMBLING THE 4100 SERIES COMFORT PLUS SYSTEM
Step 1
Remove the painted front panel of the brick storage cabinet by removing the sheet metal screws along
the top, bottom, and sides of the panel. Detach by pulling the bottom of the panel forward and down.
Step 2
Remove the limit zone cover.
Step 3
Remove the screws around the perimeter of the limit zone and around the bottom of the left side, right
side, and back upper panels.
Step 4
There are two white/blue wires which route from the limit zone through a knockout. These wires route
into the electrical compartment through a romex connector. Loosen the romex connector.
Step 5
Remove the electrical panel cover and locate the point where the white/blue wires connect to the black/
yellow wires. Disconnect the white/blue wires and route them up through the romex connector.
Step 6
Remove the one to two screws in the center of the upper right side panel. From the back of the system,
lift and remove the painted panels (Figure A).
Step 7
Locate the brick core temperature sensor(s) behind the front panel and disconnect them from their
shipping position. Carefully lay the sensor(s) aside to avoid damaging them.
Step 8
Rock the brick core (Figure B) to one side and lift top portion up and off the base (Figure C).
Step 9
Move the Comfort Plus heating system into the desired location, reassemble, and continue with the
installation instructions in this manual.
