CHIMNEY SWEEP FUNCTION
(fig. 23)
To carry out the verification of combustion
in the boiler turn the selector and stop on
the position ( ) until the green/orange led
starts to flash intermittently.
From that moment the boiler will start func-
tioning in heating mode at the maximum
power, with switching off at 80°C and
restarting at 70°C.
Before activating the chimney sweep func-
tion make sure that the radiator valves or
eventual zone valves are open.
The test may be carried out also during hot-
water service functioning.
To do so it is enough, after having activated
the chimney sweep function, to take some
hot water from one or more cocks.
Even in this condition the boiler functions at
the maximum temperature always with the
primary controlled between 80°C and 70°C.
During the entire duration of the testing the
hot water taps must remain open.
After verifying the combustion the boiler
should be switched off by placing the selec-
tor on the
OFF
position; then return the
selector to the desired function.
ATTENTION: After about 15 minutes, or
once the hot water request has been ful-
filled, the chimney sweep function auto-
matically deactivates.

BOILER SERVICING
4.12.1 Routine Servicing
To ensure continued efficient operation of
the appliance, it is recommended that it is
checked and serviced at regular intervals.
The frequency of service will depend on the
particular installation and conditions of
usage, but in general once a year should be
adequate.
It is the law that a competent person such
as a CORGi registered engineer, must carry
out any service work.
4.12.2 Combustion Check
Incorporated into the flue elbow or vertical
adaptor is a sampling point.
The grey plastic cap should be unscrewed
and the flue gas sampled using a flue gas
analyser.
During the test the boiler can be operated
in “chimney sweep mode” see 4.11.
The correct CO
2
reading can be found in
section 1.3.
4.12.3 Burner inspection
Remove the burner as described in section
6.3.
Inspect the burner and if necessary clean
using a soft brush.
Check the Ignition/ionisation electrode,
check the gap (4mm+/- 0.5mm)
4.12.4 Combustion Chamber
Remove any loose debris from the combu-
stion chamber using a soft brush and a
vacuum cleaner.
Take care not to damage the rear insulation
panel.
4.12.5 Condensate Trap
The condensate trap would not normally
require removal during service, but it can be
checked.
Water should be poured into the inner flue.
Great care must be taken to ensure no
water enters the outer flue.
Check that the water flows freely to the
drain.
Should it require removal, firstly remove
wire clip securing the condensate drain rub-
ber pipe to the condensate trap.
Remove the pipe.
Remove the two screws securing the con-
densate trap bracket.
Clean the trap and refit in reverse order.
4.12.6 Flow Switch
The operation of the flow switch should be
checked at each service.
Remove small cover retaining screw and
remove the cover.
When the pump is running and water is
flowing around the boiler, the actuator lifts
off the microswitch.
Check the operation of the actuator. Ensure
that it is free and that it lifts and returns.
If necessary lubricate the pivot point of the
actuator.
Isolate the boiler.
Drain it using the drain provided.
Remove the microswitch by carefully pulling
it forward off its mounting pins.
Remove the screw securing the mounting
plate, then pull off the plate.
Pull out the actuator pin.
Lubricate the centre “O” ring.
Refit the actuator ensuring that the flat side
of the round section is to the bottom.
Re-assemble remaining parts. (see 4.12.6
before refilling the boiler)
.
4.12.7 Aquaguard Filter
It is recommended that the aquaguard filter
is checked at each service.
See section 4.10.
