Installing oor coverings other than ceramic tiles onto the scratch coat
Before installing any oor covering other than ceramic tiles onto the scratch
coat, always consult your oor covering manufacturer to ensure product
compatibility with oor heating system.
N.B. Natural hardwood oor treatments are not compatible with
oor heating system.
THIN SET METHOD (ALTERNATIVE METHOD FOR
EXPERIENCED TILE SETTERS ONLY)
Compatibility of the thin set method
This method is only applicable if ceramic tiles or other type of similar tiles are to
be installed over a small ooring area by an experienced tile setter.
Using this method, the same concrete layer is used to embed the cables and to
secure the tiles. This technique will not raise the oor level despite the addition of
your heating system. Use a 3/8 inch (10 mm) or 1/2 inch (13 mm) notched trowel
to cover the cable with concrete-glue. To ensure a maximum adhesion, lay the
tiles on the mortar and apply pressure on it to allow air under the tile to escape.
Warning
Since the trowel comes in close contact with
the cables when using this method, you must
be very careful when applying the concrete
to avoid any damage to the cables. Any
installation-related cable damages are not
covered by the warranty.
CURING PERIOD
Initial start up of the oor heating system must be delayed until the end of the
curing period (typically 28 days). Otherwise, the concrete adhesive properties
will be compromised, thus reducing the oor covering adhesion. Contact a oor
covering specialist to ensure proper adhesion.
THIRD SERIES OF TESTS
Once the concrete embedding the cable is dry, perform the third series of
tests as described in section REQUIRED TESTS AND WARRANTY CARD,
TESTS 1, 2 & 3. Measured values must be recorded on your warranty card.
During the series of tests, if a break or damage is detected, you must call a
qualied repair technician referred by Stelpro to complete the repair. To do so,
call Stelpro’s Customer Service or consult the web site (www.stelpro.com). Any
installation-related cable damages are not covered by the warranty.
