► Clean the underside of the heat exchanger.
► Clean the siphon with water.
► Only clean the underside of the front panel.
CAREFUL

seal contain ceramic fibres.
CAREFUL
► Aer work activities, check all flue supply

10.1 Disassembly
10.2 Cleaning
The boiler and the system must be inspected annually by an qualified competent gas safe registered engineer and
cleanded if necessary. The annual maintenance interval is based on an expected operation time of approx. 1,500 heating
hours/year (average domestic use), via Comfort Touch dashboard and installerd app. If not monitored by Comfort Touch
then the boiler must be serviced annually.

► Switch o the appliance and isolate the power supply at the fuse
spur, make safe the appliance before continuing (Ref TB118).
► Close the gas valve.
► Remove the front panel of the boiler by unscrewing the two
screws (1) and then removing the panel up and forward (2).
► Wait until the boiler has cooled down. This can be done by
opening a domestic hot water tap.
► Turn the expansion vessel aside.
► Disconnect the connector of the fan.
► Disconnect the connection under the gas valve.
► Unscrew the shoulder bolts (socket) of the front cover and
remove the cover forward with the gas valve and fan (pay
attention that the burner, insulation panel, gas valve, gas piping
and the fan do not become damaged). Lay the removed front
cover with the foot supports horizontal on a smooth surface.
► The burner and the integrated insulation panel do not require
maintenance (do not need to be cleaned). Therefore, never use a
brush or compressed air to clean these components so that the
development of dust is avoided.
► Remove the siphon cup by turning it counter-clockwise and then
removing it downwards.
COMMENT
► The expansion vessel must be inspected and
tested at each annual service and if required
re-pressure to 0.75 bar.
