15 Routine servicing
ATAG Heating Technology advises on an interim service inspection with a flue 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.
15.1 Interim Service
For reasons of safety and economy, it is recommended that the boiler is serviced annually. Servicing must be
performed by a competent person in accordance with BS 7967.
After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located on
the inside back page of this document.
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 fig. 16.a);
- Unlock the fasteners A and B and remove the cover in a forward motion.
Always refit 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 fig. 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
figure 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.
- fill the siphon with
150 ml of water
.
- If a leakage has occurred to the siphon, replace the entire siphon.
