16. If a neutralisation unit is present, maintain it accord-
ing to the manufacturer’s operating instructions:
NOTICE
Reduction in the neutralisation effect
The neutralising agent in the neutralisation
unit is subject to degradation. The pH-neu-
tralising effect diminishes over time.
• Replace the neutralisation agent in the
neutralisation unit at the interval specified
by the manufacturer or if the pH value of
the condensate is < 6.5 after passing
through the neutralisation unit.
- While the heat generator is disconnected from the
electricity supply (blocking switch set to “0” heat
generator disconnected from the mains (e.g. main
switch, fuses)):
- Clean and check the neutralisation unit according
to the manufacturer’s instructions.
- If the pH value of the condensate is < 6.5, renew
the neutralisation agent according to the manu-
facturer’s instruction.
17. Cleaning and checking the condensate drain:
- Flush the condensate lines.
- Reassemble condensate drain and attach to
the siphon.
When installing the siphon and condensate
drain, the project engineering guidelines for
condensate drains must be complied with,
18. Fill the siphon (Fig. 55) and neutralisation unit, if pres-
ent, with water through the cleaning opening.
19.
Check the seal of the cleaning opening (Fig. 54) for
wear and replace if necessary.
!
WARNING
If the cleaning opening has a leak, flue gas
can escape and there is a risk of poisoning.
• Check the seal of the cleaning opening for
wear and tightness at the cover.
• Always close the cleaning opening.
20. Install the cover of the cleaning opening (Fig. 54) and
check it is gas-tight.
21. Closing the combustion chamber:
- Swivel the burner with boiler door closed down-
wards.
- Screw on the boiler door with star shaped knobs
