RX Kits. For roof and gutter deicing applications
Double runs of RX cables may be used when ice problems are only present in the gutters (Figure 7).
CAUTION: Install such that the heating cable does not touch, overlap or cross itself.
Figure 7. Double Cable Run in gutter and downspouts
Note: One should take into account the number of cables used when designing the layout. It may be
simpler to install the heating system using more short kits, or fewer large kits. Also consider what to do
with cable excess or shortage. Larger triangles or double runs in gutters and downspouts can take up
extra cable.
While not required, you may test the cable by completely unrolling the cable and plugging it in. Never
energize a coiled cable. After 10 minutes, the cable should feel warm to the touch. Resistance readings
must be performed before, during, and after installation of the cable. Reference RX Kits Part Numbers
chart (at the top of page 12) for appropriate resistance readings.
Attach the start of cable to the roof as indicated in Figure 8 or Figure 9.
Do not energize the cable.
