Manual and Installation Guide

INSTALLATION UNDER CARPET - USA ONLY
NEVER CUT OR TRIM Environ™ Flex Rolls to t into
a space that is too small.
BE AWARE of the risk of damaging the heating panels
with sharp tools, gripper rods, stretchers or seaming
irons during installation.
DO NOT drop or carelessly use tools with sharp edges
or points on top of the panels.
DO NOT walk on the panels more than is absolutely
necessary during installation.
DO NOT drop or place heavy articles on the panels.
DO NOT use folded Environ™ Flex Rolls, and care
should be taken not to fold or crease the panels at
any time during installation.
DO NOT use Environ™ Flex Rolls on stairs.
DO place Environ™ Flex Rolls directly on top of the
carpet cushion (The “carpet cushion” is also known
as the “pad”, the “foam” or the “underlay”.)
DO place Environ™ Flex Rolls directly under the
carpet.
ROLL your Environ™ Flex Rolls up should you wish
to install it at some later stage.
BEFORE YOU START
Suboor Preparation
Prepare your suboor as you normally would for a “normal” carpet installation. Ensure the suboor is
structurally sound and secure with no movement – screw or nail down any loose areas before tting
the underlayment. The suboor should be clean and dry.
To prevent damage to the panels, special attention should be paid to ensure that no nails, screws,
staple, tacks and the like are protruding from the suboor before the underlayment pad is installed.
Beware of automatic staple guns if you use one to secure the cushion / underlayment to the suboor.
A badly installed staple that protrudes from the oor can pierce and destroy the Environ cable and
mat.
Nails, screws or staples should not be installed close to the panels and power supply cables.
Permanent xtures, including built-in furniture and the like, must NEVER be installed on top of the
panels. It is important to keep an accurate record of where the panels are installed, to assist you (and
a future owner!) to easily locate them should you undertake remodelling work in the room at some
future date. Taking a few photographs during the installation process is a good idea.
COMPATIBLE CARPETS
Most modern tufted and woven carpets are compatible with Environ panels. Polypropylene, hessian
or jute secondary backings are compatible, but rubber- or foam-backed carpets are not compatible as
they trap too much heat.
The carpet must be at least 1/4” thick, but not more than 1” thick.
For the technically minded, the R-value of the carpet should not be greater than 1. Contact carpet
manufacture for the r-value rating.
COMPATIBLE CARPET CUSHIONS
Any type of carpet padding can be used as long as it has a density of 6 pounds per cubic foot. Most
good quality rebounded polyurethane (rebound) and prime polyurethane are 8 pounds per cubic foot
or more.
