9 ANNUAL INSPECTION MAINTENANCE
Maintenance must only be done by a qualified installer or technician.
The appliance must be inspected once every year according to table 9.1. Maintenance and inspection must be done once every two
years according to table 9.1
The appliance is not to be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.
Children, even if being supervised, must not play with the appliance
In the case of failure or malfunction of the appliance, do not attempt to repair it yourself. Please contact your installer. Repairs must only be carried
out by qualified technicians. Failure to comply with these requirements can compromise the safety of the appliance.
Inspection (also see 9.1, 9.2, 9.3 and 9.4)
Inspection set (article nr 101180) must be used. Switch off the boiler. Disconnect from the mains electricity supply. Remove the syphon and clean it.
Refill the condensate trap with clean water and reconnect it with the new O-ring from the inspection set (article nr 101180). Replace the electrode
with seal (parts of inspection set article nr 101180). Distance between the two pins must be 3,5± 0,5 mm. Put the boiler into operation on max. load
(see section 5.5). Determine the heat input of the boiler. Check % CO2. Repeat for min load. Check the gas-parts for leakages and correct eventually.
Check the flue-gas parts for flue-gas leakages and condensate leakages and correct eventually. Check for in general for leakages and correct if
necessary. Compare the heat input (max and min) with that measured at installation. If the figures as mentioned in table (chapter 9.1) are comparable
the inspection is done.
If the heat input is now considerably lower then there is probably an obstruction in the air inlet or the flue-outlet or in the boiler itself. Switch off
the boiler. Disconnect from the mains electricity supply. First check the airinlet and the exhaust flue-outlet. Remove the front cover, top cover and
side cover. Remove the inspection cover* of the sump on the front side beneath the controls. The inner part of the sump and the bottom part of the
heat-exchanger should be inspected and, if necessary, be cleaned.
If the bottom part of the heat-exchanger is clogged, the inspection covers on the lefthand side of the heat-exchanger should be removed*. Using a
special tool (see figure 9.1) makes it possible to clean the heat-exchanger lids partially. See page 67 for procedure putting back in place inspection
covers on the left-hand side of the heatexchanger.
In case of dirt in the sump it is also advisable to inspect the upper part of the heatexchanger as well. Remove the fan* together with the burner hood*,
the gas valve* and the gas pipe*. Now the burner* is visible and can be taken out and inspected. If necessary clean the cold side with a vacuum
cleaner (or carefully with compressed air) and a nylon brush (never use a steel brush). Inspect the combustion chamber. In case of a dirty heat-
exchanger it can be cleaned with water. Check the burner seal* and replace if necessary. Tighten with torques as mentioned in 9.3.
Put everything back in its place. Check the CO2-content and correct if necessary.
Check the gas-parts for leakages.
Check the flue-gas parts for flue-gas leakages
and condensate leakages.
*Note : be carefull during inspection not to
damage seals. Any seals damaged by ageing
or other causes must be replaced.

Maintenance (also see 9.1, 9.2, 9.3 and 9.4)
Maintenance set (article nr 101103) must be used. All parts of the set should be used as replacement.
Switch off the boiler. Disconnect from the mains electricity supply. First check the airinlet and the exhaust flue-outlet.
Remove the front cover, top cover and side cover.
Remove the syphon and clean it.
Remove the inspection cover* of the sump on the front side beneath the controls. The inner part of the sump and the bottom part of the heat-
exchanger must be cleaned.
Remove the inspection covers on the left-hand side of the heat-exchanger*. Using a special tool (see figure 9.1) makes it possible to clean the heat-
exchanger lids partially. See next page for procedure putting back in place inspection covers on the left-hand side of the heat-exchanger.
Also inspect the upper part of the heat-exchanger. Remove the fan* together with the burner hood*, the gas valve* and the gas pipe*. Now the
burner* is visible and can be taken out and inspected. Clean the cold side with a vacuum cleaner (or carefully with compressed air) and a nylon brush
(never use a steel brush). Inspect the combustion chamber. In case of a dirty heat-exchanger it must be cleaned with water. Check the burner seal*
and replace it by a new one. Tighten with torques as mentioned in 9.3. Refill the condensate trap with clean water and reconnect it.
Replace the electrode by a new one, check the distance between the two pins (3,5± 0,5 mm).
Put everything back in its place. Check the CO2-content and correct if necessary.
Check the gas-parts for leakages and correct eventually.
Check the flue-gas parts for flue-gas leakages and condensate leakages and correct eventually.
Check for in general for leakages and correct if necessary.
*Note: be careful during maintenance not to damage seals.
