5.5 Fittings
The boiler uses the following fittings:
Cock

Gas
G 3/4 MF

RR
G1/2F 3 bar safety valve fitting
Condensate discharge to be implemented
with pipe min. Ø 30 mm
5.6 Boiler assembly
• Remove the protective caps from the boil-
er pipes.
• Hook the boiler onto the bracket.
• Screw the cock on the boiler.
• Fix or weld the flared stub pipes, respec-
tively Ø 14 mm for the DHW inlet and out-
let, and Ø 18 mm for the hydraulic system
return, delivery and gas.
Figure 5.3
• Install a shut-off cock on the DHW inlet.
The purpose of the cock is to hydraulically
isolate the unit, making normal mainte-
nance possible.
• If the hydraulic heating system is higher
than the boiler surface, cocks should be
installed in order to disconnect the system
for maintenance purposes.
• Block the pipes by placing 1/2" and 3/4"

• Carry out a leakage test for the gas supply
system.
• Connect the safety valve discharge 10
(Figure 5.4) to an outlet funnel.

• Connect the condensate outlet pipe 3
(Figure 5.4) inside the residential conden-
sate outlet duct or the safety valve outlet
funnel if the outlet is resistant to acid con-
densate.
5.7 Installing the flue gas exhaust
duct
Consult the sheet provided together with
the preselected kit for information on how to
correctly install the flue gas duct.
The horizontal sections of the flue gas pipes
must have a slope of approx. 1.5 degrees
(25 mm per metre), therefore the terminal
must be higher than the boiler side opening.
Only the coaxial pipe with the terminal must
be horizontal as the discharge pipe has al-
ready been implemented with the correct
slope.
