9.11 Checking boiler efficiency

Carry out performance checks at the intervals
anticipated by the regulations in force.
• Connect a flue analyser to the flue gas anal-
ysis outlets on the flue gas exhaust on the
boiler Figure 9.15.

• Make sure that the room thermostat is in the
"heat request" position.
• Draw off an abundant amount of DHW by
opening the taps.
• Activate the "chimney sweep function" at
maximum output in heating mode (see "Set-
ting the boiler's chimney sweep function" on
page 72)
• Check the boiler combustion using the out-
lets located on the flue pipes (Figure 9.15)
and compare the data measured with the
following.

9.12 Checking the condensate dis-
charge siphon
The condensate discharge siphon 32 (Figure
9.19) does not require particular maintenance.
Simply check:
• that solid deposits have not formed and re-
move them if necessary.
• that the condensate outlet pipes are not ob-
structed.
To clean the inside of the siphon, simply re-
move it and turn it upside down so that any
impurities can be extracted.
