Step 1 – Floor Preparation
As a general rule if your floor has been
suitably prepared for tiling then it will be
suitably prepared for undertile heating.
If the heater is being fitted to a solid
concrete floor, it is essential that the
concrete
is
fully
cured
(as
per
manufacturers specifications) before the
heating is installed.
Before beginning the installation, ensure
that the floor surface is smooth, dry and
free from dust or grease.
To ensure a flat floor surface, it will be
necessary to chisel out or “chase” short
channels in the sub floor at the ‘start
point’ (see steps 4 and 5), and the ‘end
point’. This minimises the increased height
presented by the two black power supply
cables. The start and end points of the
heating element should be at least 50mm
apart (no closer) or maximum 100mm (see
sizing guide).
Never cross over any of the heating
elements
(check sizing guide for colours).

The lowest ambient temperature at which the heating element may be installed is 0
⁰
. Heating
elements shall be installed at a distance of at least 30mm from conductive parts of the
building, such as water pipes.
