7.10 Checking the flue system
The flue system should be visually checked
for soundness. Check all clamps, gaskets and
fixing are secure and tight.
Ensure that the flue terminal is sited correctly
in accordance with the flue fitting instructions
and Fig. 5.1 on page 26 of this manual.
To carry out a combustion check refer to the
instructions given in the section "Combustion
analysis check" to page 51.
Reference figures are given in the "Technical
Data" section page. 18 of this manual (Flue
gas figures).
7.11 Check pump operation/pump
release
The pump electronic control circuit automati-
cally releases the pump.
Connect the boiler to the mains .
Make sure that the ambient thermostat is in the
"heat demand" position.
Check that the boiler with the gas cock shut-
off goes into ignition lockout (Er01) and, in the
meantime, check the pump release.
The pump release can be verified by checking
that the pump motor vibrates.
If the pump motor does not vibrate, release the
boiler from its lockout due to gas failure by press-
ing the reset button on the control panel and re-
peat the sequence a maximum of 10 times.
If the pump does not release, contact technical
support.
Once the pump has been released, open the gas
cock and check that the boiler operates correctly
both in domestic hot water and heating modes.
