BRICK CORE TEMPERATURE SENSOR INSTALLATION
Step 1
Remove the screw(s) around the brick core temperature sensor
hole(s) in the galvanized front panel.
Models 5130 and 5140 have an upper and a lower brick
core temperature sensor.
Step 2
Insert the brick core temperature sensor(s) through the hole(s) in the
galvanized front panel. If installing a system with two sensors, be
sure the one marked as the upper sensor is installed in the upper
position and the one marked as the lower sensor is installed in the
lower position. The sensor(s) must pass through the blanket insulation
and into the brick core. Holes have not been pre-drilled through the
insulation. Use the sensor(s) to aid in making a passageway by
rotating the sensor(s) side-to-side while gently pushing inward.
Step 3
Once the brick core sensor(s) is installed, put the screw(s) back into position in the galvanized front
panel to hold the sensor(s) in position and to provide the electrical ground.
Step 4
Check the non-insulated element terminations to make sure they do not come within 1/2" of any surface
area on the system.
Step 5
Re-install the painted front panel, using the previously removed screws.
CAUTION
Risk of improper opera-
tion. Proper installation of
the brick core tempera-
ture sensor(s) is critical to
the operation of the
Comfort Plus Hydronic
heating system. Read and
follow installation instruc-
tions carefully.
Step 2
Install the front air channel by placing
the bottom in first, with the air deflec-
tors (arrow shaped pieces) facing
inward. Refer to the Air Channel
Placement (Figure 6) and the Parts
Diagram (Page A.02) for proper
placement and installation 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 14 inch lbs. Refer to Figure 5 for
proper positioning.
