A water conditioning product is supplied with the
boiler.
This must be added to the heating circuit when the
installation is filled with water. INIBAL: dose = one li-
tre to one hundred litres. If the installation is not
new, ALWAYS flush out the system using clear wa-
ter before finally filling it.

This THR boiler model cannot be fitted for use in a
floor heating system (unless it is installed with an in-
dependant electronic control)
7+5ZLWKRXWVLGHVHQVRURQO\
To operate the THR with outside sensor as part of a
floor system, the internal regulator parameters have
to be changed when commissioning the system.
This modification is explained in § 2.2.2 - IV - IN-
STALLATION. Incorrect changes to these parame-
ters may cause damage to the installation.
A safety device has to be fitted in order to comply
with the regulations. This manual reset device,
which is independent from the regulation system,
must cut off the heat supply and should function
even in the absence of power or motor fluid. The
connection of a switching device to connector No. 6
of the control box satisfies this requirement.

VHQVRU
Installing this type of boiler as part of a floor heating
system imposes the same constraints as for the pre-
vious version, namely that the internal regulator pa-
rameters have to be changed (§ 2.2.2 - IV -
INSTALLATION) and an independent safety device
has to be fitted.
