9.1.3 Fitting
During maintenance the front plate seal needs to be replaced.
When assembling, check the other seals for damages, hardening,
(hairline) fractures and/or discoloration. Where necessary, place a
new seal. Also check the correct positioning.
1. Check that between the flange of the shoulder bolt and the front plate, there is a
thin layer of ceramic grease.
If there is no or insufficient grease, it must be applied (see image).
2. Note: Replace the seal around the front cover. Clean the seal ring chamber with
a soft brush and make sure the new o-ring is pressed in well all around. Avoid
stretching or tearing. Place the front lid on the heat exchanger and secure it with
the special shoulder bolts (hex key). Make sure that the o-ring remains in place
when installing the front plate. Evenly tighten the shoulder bolts crosswise
manually (10 – 12 Nm). For the sequence of tightening, see image.
3. Evenly manually tighten the boiler controller bolts crosswise.
4. Fit the gas coupling under the gas block.
5. Fit the connector onto the fan and the ignition unit onto the gas block.
6. Fit the condense outlet tray by sliding it into the outlet stump of the switcher (1), with the
siphon connection, before the bottom tray. Then turn the condense outlet tray to the left (2)
and push it down into the siphon connection (3). Make sure that the rear of the condense
outlet tray ends up resting on the cam at the back of the bottom container (A).
7. Fill the siphon with water and fit it onto the connection under the condense outlet tray.
8. Slide the flue gas pipe, while turning it to the left, with its top around the flue gas adapter in
the top lid. Insert the bottom into the condense outlet tray, drag the gasket down and
tighten the swivel head to the right.
9. Open the gas valve and check the gas couplings under the gas block and on the assembly
bracket for leakage.
10. Check the CH and the water pipes for leakage.
11. Insert the plug into the socket.
12. Switch the unit on with the
13. Check the front lid, the connection of the fan to the front lid and the flue tube parts for leaks.
14. Check the gas-air regulation (see par. 7.7 and par. 7.8) and check the gas coupling on the
gas block for gas tightness.
15. Assemble the cover and tighten the two screws to the left and the right of the display, and
close the display cover.
16. Check the heating and the hot water provision for correct functioning.
