Installation
Step 3 Insert the brick core temperature sensors through the holes in the galvanized front panel. The sensors
must pass through the blanket and board insulation and into the brick core. Use the sensors to aid in
making a passageway by rotating the sensors while gently pushing inward.
Step 4 Once brick core sensors are installed, re-install sensor mounting screws to secure and ground the sensors.
Step 5 Re-install the painted front panel, using previously removed screws.
BRICK CORE TEMPERATURE SENSOR INSTALLATION
Step 1 Remove the screw(s) by the brick core temperature sensor connector
holes in the galvanized front panel.
Step 2 Route the brick core temperature sensors through the clear plastic
tube until within six inches of the relay driver board. Cut tube and
sensor wires to length as needed. The yellow wire from each sensor
must be connected to the Y terminal of the proper sensor connection
terminal block, and red to R. Polarity of sensors is critical.
Sensor connections MUST be installed as follows:
• Single Module - 8150 or 8180 (Figure 16)
• Bottom sensor to core C
• Second sensor to core D
• Third (if equipped) to core E
• Dual Module - 8155, 8185, and 8188 (Figure 16)
• Left module • Right module
• Bottom sensor to core F • Bottom sensor to core C
• Second sensor to core G • Second sensor to core D
• Third (if equipped) to core H • Third (if equipped) to core E
Risk of improper operation.
Proper installation of the brick
core temperature sensor is
critical to the operation of the
heating system. Read and
follow installation instructions
carefully.
