Installation of Environ™

Flex Roll System

• Once the underlayment has been installed in the correct manner, remove

your Environ™ Flex Rolls from the box, unroll it completely and place it in the

required position on top of the underlayment.

• Make sure that Environ™ Flex Rolls are installed with the correct orientation.

Ensure that the side marked “THIS SIDE UP” is facing upwards.

When positioning the roll on the underlayment, be aware of the

following:

• Ensure the power supply cables can reach the thermostat to which it will be

connected.

• Wherever possible, run the power supply cables parallel or at right angles to the

walls, and avoid high-trafc areas.

• Wherever possible, keep the corner where the power supply cable enters the

roll away from high trafc areas.

• NEVER run the power supply cables under or over the rolls.

• The power supply cables (non-heating leads) must be installed in accordance

with applicable National Electric Codes, Canadian Electric Codes, and local

codes.

• The power supply cables (non-heating leads) are to be installed in listed conduit

as the cables exit the oor if required by local code.

• Environ™ Flex Rolls can be cut and turned at 90º or 180º (as shown in the

bottom picture) to cover the total area (cable should not be cut)

• Ensure that there is a minimum gap of 1.5” (40mm) between heating cables in

adjacent runs of mat.
