9 MAINTENANCE
The unit and the installation must be checked by a certified installer, and cleaned if
necessary.
CAUTION
Work on gas carrying parts may only be carried out by a certified
installer.
After work, check the flue gas carrying parts for air tightness.
If the unit has just been operational, some parts may be hot.
9.1.1 Disassembly
1. Switch the unit off with the button.
2. Remove the plug from the socket.
3. Shut the gas valve.
4. Open the display valve and loosen the two screws on the left and right of the
display, and remove the front panel.
5. Wait until the unit has cooled down.
6. Unscrew the coupling nut at the bottom of the flue tube to the left.
7. Slide the flue gas pipe upwards (1) with a turn to the left until the bottom of the pipe
reaches above the coupling of the condense outlet container. Pull the bottom of the
pipe forward (2) and remove the pipe by rotating it to the left and down (3).
8. Lift the condense outlet tray from the connection of the siphon (4) on the left, and
turn it to the right with the siphon connection over the edge of the bottom tray (5).
Push down the condense outlet tray at the back from the connection to the heat
exchanger (6) and remove it from the unit.
9. Take the connector from the fan and the ignition unit from the gas block.
10. Disconnect the coupling under the gas block.
11. Unscrew the shouldered bolts (hex key) of the front lid and remove it to the front,
complete with gas block and fan (be careful not to damage the boiler controller,
insulation plate, gas block, gas pipe and fan). Lay the removed front lid with the foot
rests horizontally on a flat surface.
12. The boiler controller and the integrated insulation plate do not require any
maintenance (do not need cleaning). Therefore never use a brush or compressed
air to clean these parts, in order to avoid dust developing.
9.1.2 Cleaning
1. Clean the heat exchanger with a brush or vacuum cleaner, from top to bottom.
2. Clean the bottom of the heat exchanger.
3. Clean the condense outlet tray with water.
4. Clean the siphon with water.
5. Clean the inside and bottom of the front plate with a soft brush.
