MAINTENANCE
2 - CLEANING THE CONDENSOR
- Unclip the top of the boiler casing by pulling it
upwards (section 3 - page 14 - chapter V - INS-
TALLATION),
- Remove the condenser insulation (S, fig. 41),
- Unscrew the fixing screw (F) from the condenser
cover (G),
- Remove the swirlers (N) of the tubes (H) of the
condenser (10),
- Clean the condensor tubes (H) using a bottle
brush,
- Position the swirlers (N) in the tubes (H) of the
condenser (10) ensuring that the following layout
is respected:
• identify the 4 tubes aligned opposite the notch
of the jumper used to support the threaded rod
(R, fig. 41),
• leave the tube closest to the jumper empty,
• position the first swirler in the following 2 tubes,
• continue to distribute the swirlers by fitting
them in a circular direction.
The tube closest to the jumper must re-
main empty.
- Final result:
- Check that the combustion products can flow
freely :
• unscrew the plug to check the combustion pro-
ducts (15),
- Check that the sealing joint is properly position-
ned (I) when replacing the cover (G):
Remarks:
- If after cleaning the temperature of the flue
gasses remains excessive (> 230°F = 110°C),
perform a boiler check.
- Make sure that the sealing joint on the cover (I)
are maintained in good condition and replace it if
