Heating Mats – NADWM

Quick Menu

Can the cold lead of your NADWM system be trimmed?

Yes, you can trim the cold lead.

As the lead for the heater is 9 feet, it isn’t uncommon to have an excessive amount left once installed. Instead of leaving the excess lead wire in the wall or crowded in the electrical box, Warmup recommends trimming the lead to a sizable length suitable for your installation.

However, make sure to leave at least 3 feet of lead past the factory joint. Please refer to the installation manual for further information.

Note that the factory joint must be placed in thin-set, and flat on the floor.
