Installation Guide
RECORD YOUR SYSTEM’S OHM READINGS HERE FOR READY
REFERENCE
Four (4) Ohm readings should be taken from each mat at each stage of
the oor warming system installation as listed below. This is necessary
to ensure that your system is functioning properly and that no breaks or
shorts have occurred that could affect its performance or integrity.
1. Core to Core: This is the reading between the two inner conductors
of the lead wires.
2. Sheath to Sheath: This is the reading between the two outer ground
sheaths of the lead wires.
3. Core to Sheath START lead: This is the reading between the inner
core and outer ground sheath of the lead wire at the beginning of the
mat. This reading should be innity.
4. Core to Sheath END Lead: This is the reading between the inner core
and outer ground sheath of the lead wire at the nish point of the mat.
This reading should be innity.
A digital Ohm meter should be used when taking readings. The meter
should be set to measure resistance in the range of 0 - 200 Ohms and
fresh batteries should be installed before commencing.
NOTE: Remove the UL label(s) with the factory Ohms reading from
the warming mat(s) and store in a convenient location for future reference,
preferrably at the electrical panel box with the oor warming installation
