Step 4 Once in place, adjust the leveling legs on the bottom of the system as necessary to prevent rocking. If not
placed properly the system may bend or twist during the brick loading process, making element and brick
core temperature sensor installation difficult. Leveling legs should be extended no more than one (1) inch.
Step 5 Remove the painted front panel of the electrical compartment by removing the screws along the edges.
Locate the element screw kit and the outdoor sensor.
Step 6 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 7 Locate the element wiring harnesses behind the front painted panel. Carefully position them to avoid
damage during the brick loading and wiring processes.
Step 8 4100 SERIES ONLY. Locate the brick core temperature sensor(s) behind the front panel and discon-
nect them from their shipping position. Carefully position the sensor(s) to avoid damage during brick
loading and wiring.
Models 4130 and 4140 have two brick core temperature sensors.
Step 9 Remove the galvanized front panel and set it aside.
Step 10 Starting at the bottom, carefully lift the two insulation blankets, one at a time, and drape them over the top
of the system.
Use face mask, gloves, and long sleeved garments when handling insulation materials in
compliance with generally accepted safety practices.
Step 11 Remove the front air channel by pulling out on the bottom of the air channel on a 3100 series or the top of
the air channel on a 4100 series.
BRICK LOADING
Load the brick, one row at a time, using a left side, right side, center pattern.
Start at the back of the brick core and work forward. Make sure the brick are
placed so the grooved side is facing up and the ridges are on the left and right.
(See Figure 6.)
BRICK INSTALLATION TIPS:
• Install bricks carefully to avoid damage to the insulation panels.
• Remove loose brick debris to prevent uneven stacking of brick, as this can make installation of the elements
and the brick core temperature sensor(s) difficult.
• Brick rows MUST line up front to back and side to side.
• Half brick makes brick loading easier by evening out the stacks. Use HALF BRICK (white boxes) in the
proper rows and positions
as indicated in Figure 6.
• Alternate the direction of
the brick’s indicator in
every other brick row.
See Figures 4 and 5.
• All bricks in odd
numbered rows (1, 3, 5,
7, 9, and 11) must have
the indicator facing
forward as shown in
Figure 4.
• All bricks in even
numbered rows will have
indicator facing back.
See Figure 5.
Risk of fire. Can cause
personal injury or death. DO
NOT operate the system if
damage to the insulation
panels on the inner sides of
the brick core occurs.
