• Configuration without cover kit (boiler type C).
By leaving the side plugs fitted, it is possible to install the appli-
ance externally, in partially covered places, without the cover
kit. Installation takes place using the Ø60/100 and Ø80/125
concentric horizontal intake/ exhaust kits. Refer to the para-
graph relative to indoor installation. In this configuration the
top cover kit guarantees additional protection for the boiler. It
is recommended but not compulsory.
• Diaphragm installation.
For correct functioning of the boiler it is necessary to install a
diaphragm on the outlet of the sealed chamber and before the
intake and exhaust pipe (Fig. 12).
The choice of suitable diaphragm takes place on the basis of the
type of pipe and its maximum extension: this calculation can be
carried out using the following tables:
N.B.: the diaphragms are supplied together with the boiler.

• Intake diaphragm installation.
For correct boiler functioning with Ø 80 separator kits and
drain measuring > 1 m a diaphragm Ø 47 must be installed on
the sealed chamber intake hole and before the intake pipe (Fig.
13). The choice of suitable diaphragm takes place on the basis
of the type of pipe and its maximum extension: this calculation
can be carried out using the following tables:
