TECHNICAL DATA
When installing horizontal pipes, a minimum inclina-
tion of 1.5% towards the boiler must be maintained, and
a section clip with pin must be installed every 3 metres.
Installation inside the recessed frame
In this mode, install the ue according to your needs using the ap-
propriate pre-sections in the frame to exit from its clearances.
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 in-
take and exhaust pipe.
e appropriate diaphragm is chosen based on type of pipe and its
maximum extension: this calculation can be made using the
tables below:
e diaphragms are supplied together with the boiler as
standard.
