EM2-CM-MAT HEATING SYSTEM (1)
The heating mat “EM2-CM-Mat” is a constant
wattage heating device for a permanent
installation in screed or sand under paving slabs.
It is a 230Vac system regulated by a control unit.
(Control unit provided separately.)
EM2-CM-Mat is a preterminated and ready to
install heating mat with 1 cold lead connection
and a power output of approx. 300 W/m² or 25
W/m of heating cable. All mats have a width of
0.6 m and are available in lengths from 2 m up
to 21 m. The cold lead cable has a length of 4 m,
and should be installed in a conduit.
The minimum cable spacing is 10 cm. With 10
cm spacing the power output will be 300 W/m².
Spacer, Junction box (4) and
supply lead (9)
When it is necessary to loosen the heating cable
from the mat, the plastics strips (VIA-Strips-PL)
will help maintain the correct spacing (10 cm).
Extension of the cold leads needs to be done in a
junction box. The connection between the control
panel and the junction box is made by a suitable
supply lead.
Controller (8)
nVent offers control units specially designed
for ramp heating applications. They incorporate
combined temperature and moisture sensors to
ensure efficient operation of the system.
Panels (7)
nVent offers a range of standard panels
specifically designed for ramp heating
applications. Each panel contains a built in

LAYOUT CONSIDERATIONS
Area to be heated
Determine the exact area to be heated, e.g. wheel
tracks. Consider the following factors:
Heat at least one
metre into the
covered area.
nVent.com | 9
Cold lead
Conductor
Ohmmeter
First make sure that the area to be heated
complies with the data in the design instructions.
Establish where the junction boxes are to be
installed and check that the connection leads are
long enough.
The length is 4 m. Thoroughly clean the
substratum before starting to install the heating
mat, as sharp objects can damage the heating
cable.
The EM2-CM-Mat must not be shortened or spliced.
PREPARING SUBSURFACE
The heating mat should be installed on a
stable subsurface. In suspended structures
the substratum may consist of finished slabs,
prestressed concrete or a suspended structure
with poured concrete.The heating mat can be laid
on all subsurfaces.
In the case of poured concrete, it should be
ensured that the surface is smooth and all
sharp objects are removed. Ramps on a solid
substratum do not require any additional thermal
insulation.
Appropriate preparations should be made for
installing the temperature and moisture sensor.
CABLE RESISTANCE AND INSULATION RESISTANCE TEST
Testing the heating mat involves the measuring
of the conductor resistance and the cable
electrical insulation resistance.
The conductor resistance is measured with
an ohmmeter. A deviation of up to 10% from
the nominal resistance is permissible. See table
on page 5.
10 | nVent.com
The insulation resistance should be measured with the aid of a 2500 Vdc
(500 Vdc minimum) insulation resistance tester. The reading should be 100Mohms min.
Record all the measured values on the Installation Test Record provided.

HEATING MAT INSTALLATION
All connections and electrical testing should be carried out by a qualified electrician.
The heating mats should be installed for ramp and driveway heating.
For irregular shaped areas, it is acceptable to cut the tape of the mat (not the heating cable) in order to
cover the entire area.
However, the heating cable within the mat should:
not be cut or damaged,
not be crossed over
not be installed within 10 cm of another section of heater,
not be installed across expansion joints or separate concrete slabs.
Minimum cable spacing is 10 cm
The heating mats must be secured to the underlaying surface to prevent movement during the
installation.
The cold lead cable should be protected in a conduit. The entire length of heating cable should be
covered by wet sand-cement mixture, screed, or dry sand depending on the selected top surface.

Purpose
The drain tracing system ensures that melt water
can drain away.
Note: the drain tracing circuit should be
controlled by the same control system as the
other heating circuits.
Install Junction box (10)
Choose a position:
close to the drain
indoors if possible.
Install Connection Kit (11)
Terminate the GM-2XT heating cable into the
junction box in accordance with the instructions
provided with the Connection Kit.
Lay out the Heating cable (12)
Protect the heating cable with conduit
between the junction box and the drain. Trace
the entire length of the drain to ensure that melt
water will always have a drain-off path.
Install the End Seal (13)
Install the end seal following the instructions
provided with the End Seal kit.
Perform an Insulation Resistance Test
The insulation resistance test detects damage to
the heating cable such as
cuts or punctures. It should be carried out
using a 2500 Vdc instrument. Lower voltage
instruments are less sensitive and are not
recommended. The instrument should have a
test voltage of not less than 500 Vdc.
Proceed as follows:
Connect one lead to the heat strip braid.
Connect the other lead to both heat strip
conductors together.
Apply voltage. The resistance reading must be
greater than 100 MΩ.
If the insulation resistance is less than this,
the heat strip is damaged. Where possible,
locate the fault and rectify. Record the
insulation resistance value on the Installation
Test Record.
