to tee the heating cable, use two runs—by running
the heating cable down to the bottom and then
back to the top.
• Leave drip loops below the downspout at bottom.
• If a single run of heating cable is used, the end
seal should be looped back up at least 12 inches
(30 cm) inside the downspout.
• If the downspout ends near the ground, water will
refreeze on the ground and build up around the
downspout, eventually blocking the opening.

considerations
To prevent mechanical damage, do not leave the end
seal exposed at the end of the downspout.
