During maintenance the seal front plate 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.
If retarders are not fitted, or incorrectly fitted, it may lead to
serious damage.
1. Place the retarders in the heat exchanger.
2. 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).
3. 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 plate on the heat
exchanger and secure it with the special shoulder bolts (Allen bolts). ).
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.
Please note: The front plate in the image has 11 shoulder bolts
(EKOMB28AAV1H, EKOMB33AAV1H). The front plate of the
EKOMB22AAV1H has 9 shoulder bolts.
4. Evenly manually tighten the boiler controller bolts crosswise.

connection (3). Make sure that the rear of the condense outlet tray ends up
resting on the tab at the back of the lower tray (A).
8. Fill the siphon with water and fit it onto the connection under the condense
outlet tray.
9. 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 nut to the right.
10. Open the gas valve and check the gas couplings under the gas block and on
the assembly bracket for leakage.
11. Check the CH and the water pipes for leakage.
12. Insert the plug into the socket.
13. Switch the unit on with the
14. Check the front lid, the connection of the fan to the front lid and the flue tube
