UL 1683, 65.3h – Mark the appropriate circuit breaker referencing which
branch circuit supplies the Warmset heating system. When using multiple
mats, the mats should be connected in parallel. If multiple mats are being
installed, label the leads as they enter the junction box. Connect these mats to
the line going from the junction box to the electrical box.
The thermostat
fl
oor sensor can be installed with or without electrical conduit
(recommended for added protection) depending on code requirements. Do
not place the sensor in the same conduit as the cold leads to avoid possible
interference.
Open a separate knockout in the bottom of the thermostat box, and feed the
sensor (and conduit, if used) through the knock-out. Feed it down through
the cut-out in the bottom plate, and out into the
fl
oor where the heating mat
will be installed.
