• Connect a flue analyser to the flue analysis
outlets on the flue exhaust of the boiler Fig.
9.15.

• Activate the “chimney sweep function” at
maximum heating power (vedere "Setting
the boiler chimney sweep function" a pag.
77).
• Make sure that the ambient thermostat is in
the position “call for heat”.
• Withdraw an abundant amount of d.h.w. by
opening the faucets.
• Check the combustion of the boiler using the
outlets located on the flue tubes (Fig. 9.15)
and compare the data measured with that
following.

9.10 Checking the condensate drain
pipe
The condensate drain pipe 36 (Fig. 9.18) does
not require any particular maintenance but
just check:
• That no solid deposits have formed, if so re-
move them.
• That the condensate drain piping is not
clogged.
Unscrew the plug to clean inside the pipe.
