WARNING!
Safety Precaution:
Radiators are hot when in use, and as such,
present a risk of burns to users on prolonged
contact.
The temperature of a radiator is dependent on the
temperature of the system water, as set by the
system installer or end user.
Installers and users should ensure that those who
come in to close proximity to hot radiators are
aware of the risks of burns.
Installers and users should take all necessary
steps to minimise the risk of burns. If the risk
is significant, consideration should be given to
installing low temperature radiators, or to placing
guards in front of radiators.
For the correct installation of radiators it is
essential that the fixing of the radiator is carried
out in such a way that it is suitable for intended
use AND predictable misuse.
A number of elements need to be taken into
consideration including fixing method used
to secure the radiator to the wall, the type
and condition of the wall itself, and any additional
potential forces or weights, prior
to finalising installation.
IN ALL CASES IT IS STRONGLY RECOMMENDED
THAT A SUITABLY QUALIFIED PROFESSIONAL
INSTALLER OR SIMILAR TRADESPERSON
CARRIES OUT THE INSTALLATION.
PLEASE NOTE: The fixing materials provided are
only intended for installation on walls made of
solid wood, bricks, concrete or on timber frame
stud walls where the fixing is in to the timber.
All walls being considered should have no more
than a maximum of 3 mm wall finishing. For walls
made of other materials, for example hollow
bricks, please consult your installer or specialist
supplier. ONCE AGAIN, IF YOU ARE UNSURE, IT IS
STRONGLY RECOMMENDED THAT A SUITABLY
QUALIFIED PROFESSIONAL INSTALLER OR
SIMILAR TRADESPERSON CARRIES OUT THE
INSTALLATION.

Information for the installer
Important Notes:
• The header with the flow /return connections
contains a baffle and is identified by a sticker
(shown on the previous page).
• Connections in the opposite header are used as
vents or drains depending on the orientation of
the radiator.
• TBSE (Top Bottom Same End) connections
(AB/GE/HF/CD) and TBOE (Top Bottom Opposite
End) connections (AC/CB/GF/HE) must be
specified at time of order as they will NOT
function correctly with a baffle.
• Ensure there is no trapped air in the radiator
by adequately bleeding the system during
installation.
• Flow rate may need to be adjusted/balanced
for optimum performance.
• Radiator should be filled slowly from the bottom
where possible.
