9.1.3 Fitting
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.
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. Check whether the seal around the front plate has been fitted correctly.
Place the front plate on the heat exchanger and secure it with the special
shoulder bolts (Allen bolts). 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
The front plate of the EHOBG12AAV1 and EHOBG18AAV1 has 9 shoulder
bolts.
3. 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 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
