GENERAL INFORMATION
1 GENERAL INFORMATION
1.1 General Safety Information
9 This instruction booklet is an integral part of the instruc-
tion manual of the single appliance Condexa PRO, to which
you are referred for the GENERAL WARNINGS and for the BASIC
SAFETY RULES
9 The instructions provided for the cascade accessories are an
integral part of this manual. They must be referred to and
must not be disposed of.
1.2 Description of the appliance
Condexa PRO can be combined in cascade with other generators
in order to create modular thermal power units, consisting of
thermal modules connected hydraulically, the electronic con-
trols of which communicate via bus. In fact, each thermal mod-
ule has been designed to combine with other identical units, up
to a maximum number of 10 units, with the exception of model
135 whereby the maximum number of models in cascade is 8.
For each thermal model it is possible to congure the different
types of installations either in line (i.e. Front) or back to back (i.e.
Back to Back).

GENERAL INFORMATION
1.4 Installation premises
The thermal module must be installed in premises used exclusively for the latter conforming to standards and legislation in force
and where combustion exhaust products and combustion air intake is conveyed out of said premises.
Where combustion air is instead taken from the installation premises then the latter must be equipped with suitably sized vents
conforming to standards.
Space required for in line layout (FRONT)
≥ 1 m
≥ 0,5 m
≥ 0,5 m
Space required for back-to-back layout (B2B - BACK TO BACK)
≥ 1 m
≥ 1 m
≥ 0,5 m
≥ 0,5 m
9 When installing the boiler, allow sufcient space around it to access all safety and control devices and to permit easy mainte-
nance.
9 The height of the installation room must meet the re-prevention requirements and current regulations in force in the country
of installation.
9 Check that the electrical protection rating of the thermal module is sufcient for the characteristics of the installation room.
9 If the thermal modules are powered by combustible gas with a specic weight exceeding that of air, the electrical parts must
be positioned at a height exceeding 500 m from the ground.

2.1 Preliminary installation measures

4
2 modules 3 modules
To correctly install the modules, the installer must take into consideration a series of tolerances on the installation distances as
established during the design stage.
In particular:
1 the plates for securing the frames have slots and must only be secured after having tted the manifolds.
2 if making connections between manifolds, tighten the ange to ensure that the seal adheres and reduce the clearance on
the total length of the manifolds.
3 the thermal module can slide (right-left) on the supporting bracket to facilitate any adjustments which need to be made
during the installation stage of the hydraulic ramps.
4 in the case of installations with a manifold for 3 modules, the central frame has a greater tolerance.
