Table 8: Hydronic Heat Section with Short Control Box Dimensions
Units With Hydronic Heat (Sizes 007–012)
The hydronic heat section can be supplied with a short (4¼''
high) control box or a long (13½'' high) control box
depending on the number of options selected. Observe the
control box to determine which one was supplied for the job.
Short Control Box
If the short control box was supplied, eld wiring should be
brought into the 2'' x 4'' junction box which is located on the
right-hand side of the heat section (Figure 14.)
Long Control Box
1. If the long control box was provided, make electrical
connections to a eld supplied junction box that should
be fastened to the oor beneath the control
(Figure 15).
2. Locate the long control box. The power wires for the
control extend through the piece of exible conduit that
exits from the bottom of the control. These wires should
be connected to the incoming power at the junction box
installed in Step 1.
Remote Control — For units with remote mounted
thermostat, refer to page 14.
