1.0 Do’s and Don’ts
2.0 General Description
Plan the installation carefully, and consider the following:
l
The underfloor heating must be connected to a traditional
two pipe heating system.
l
Carefully consider the manifold position so it is both near
the area(s) to be heated, and also easily connected to the
heating pipework.
l
We recommend that the underfloor heating be connected as
a separate timed heating zone. This may require an
additional timer and zone valve, which are not supplied.
Should it be connected into an existing heating zone,
consideration must be given to the response time of the
heating system.
l
If you are unsure of any of the above points, contact your
heating engineer.
The Cliprail Zone Pack consists of a MYSON FLOORTEC
Compact Underfloor Heating Control Unit that takes heat from
a normal heating system and distributes it into a screeded floor,
via manifolds and 17/2 PeX-a pipe. The installation instructions
for the MYSON FLOORTEC Compact Underfloor Heating
Control Unit are supplied in its box, and are not covered in
detail here.

Important Notes
These figures assume 200mm pipe spacings, a 75mm deep
screed, 8ºC difference between the 17/2 PeX-a underfloor
heating flow and return and an air temperature of 20ºC.
Calculated in accordance with BSEN 1254-:1997.
Care must be taken when using underfloor heating with floor
coverings, which may be affected by heat, such as wood or vinyl
products. Consult the flooring manufacturer for guidance.
The underfloor heating installer must ensure the heat
requirement of the area to be heated is within the potential
outputs detailed above. Supplementary heating may be
required if the heat requirement is in excess of the above
outputs, if the system is to be operated intermittently, or a swift
response time is required. MYSON is not responsible for
providing any form of temperature guarantee.
