16 Routine servicing
ATAG Heating Technology advises on an interim service inspection with a fl ue gas analyser. A full
strip down service is recommended at regular intervals or where analyser readings are not within
correct safety standards.
Required tools:
- Cross head screwdriver
- T-handle key set with 3 bits (hex key 4mm, hex key 5mm and cross head PZ2)
- Open end wrench 8mm
In order to perform maintenance, the following actions have to be taken:
- Switch off the electrical power to the boiler;
- Remove the screws from the 2 fasteners A and B (see fi g. 16.a);
- Unlock the fasteners A and B and remove the cover in a forward motion and remove the earth cable
(when present) from the cover.
Note that there is an earth cable (when present) to disconnect when removing the boiler front panel.
Free space for removing the connector is about 400 mm. Remind to connect this earth cable (when
present) when placing back the boiler front panel and take care the wire does not get stuck between
front panel and boiler. Always replace and turn the 2 screws tight in the fasteners A and B.
Air box/cover
The cover also doubles as air box:
- Clean the air box/cover with a cloth and a non-abrasive cleaner;
Siphon (see fi g. 16.b)
The degree of pollution resedue in the siphon is an important indication for the need
of maintenance
- Turn the control unit towards by moving the handle (C) slightly to the left (see
fi gure 16.a);
- Turn/pull the sealing ring (1) downwards;
- Turn the siphon securing clip (2) anti-clockwise;
- Pull the siphon cup (3) and siphon pipe (4) out of the heat exchanger;
- Take the siphon cup and pipe out of the boiler by moving it downwards or turn it in
forward motion upwards along the heat exchanger;
- Clean the parts by rinsing them with water;
- Check the O-ring of the siphon cup and replace it if necessary;
- Grease the O-ring again with acid-free O-ring grease to simplify the reassembly.
Reassembly takes place in reverse order.
- fi ll the siphon with 150 ml of water .
- If a leakage has occurred to the siphon, replace the entire siphon.
