INSTALLATION
2.3

Installation premises

The thermal module Condexa PRO can be installed in rooms that
are permanently ventilated and equipped with suitably sized
ventilation openings in line with Technical Standards and Regu-
lations applicable to the installation site.
9
When installing the boiler, allow sufficient space around it
to access all safety and control devices and to permit easy
maintenance.
9
Check that the electric protection level of the appliance is
suitable for features of the room where it is installed.
9
Make sure that comburent air is not contaminated by sub-
stances containing chlorine or fluorine (elements found in
sprays, paints, detergents etc.).
9
Thermal modules may be installed outdoors only if the spe-
cial accessory is fitted.
0
Do not obstruct or restrict the air vents in the room where
the boiler is installed. A free air supply is essential for correct
combustion.

Recommended minimum distances

Clearances for the assembly and the maintenance of the appli-
ance are shown in the figure.
The minimum surface of ventilation openings is 3,000 cm
gas fuel heating systems.
2.4 Installation in older systems and systems
requiring modernisation
When installing these boilers in older systems or systems requir-
ing modernisation, always perform the following checks:
− Make sure that the flue is able to withstand the temper-
ature of the combustion gases and that it has been de-
signed and made in compliance with applicable stand-
ards. The flue must also be as straight as possible, sealed,
insulated and not blocked or choked. See Paragraph "
Discharge of combustion products" for any additional in-
formation.
− Make sure that the electrical supply system has been in-
stalled by a qualified electrician in compliance with ap-
plicable standards
− Make sure that the fuel feed line and any storage tank
are made and installed in compliance with applicable
standards
− Make sure that expansion vessels are big enough to con-
tain the additional volume generated by thermal expan-
sion
− Make sure that the flow rate, head and direction of flow
of the pumps are suitable and correct
− The system has been washed, cleaned of mud and grime
and water seals have been checked
− A treatment system is fitted when the supply/refill water
has values other than those indicated in Paragraph "Wa-
ter quality requirements"

The manufacturer declines all responsibility for damage
caused by incorrectly constructed flue systems.
