• Carry out a leakage test for the gas supply
system.
• Connect the safety valve discharge 8 (Fig-
ure 5.4) to an outlet funnel.

• Connect the condensate outlet pipe 4 (Fig-
ure 5.4) inside the residential condensate
outlet duct or the safety valve outlet funnel
if the outlet is resistant to acid condensate.
5.7 Installing the flue gas exhaust
duct
Consult the sheet provided together with the
preselected kit for information on how to cor-
rectly 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 already
been implemented with the correct slope.
