Step 1: Condensate trap
- First remove the screw (7);
- Pull the condensation cup (8) downwards, out of the condensate tray (14)
Check this for impurities. If there is not a lot of impurities it is not necessary to
clean the condensate tray (Go to Step 3). If there is a lot of impurities in the cup
it is necessary to remove and clean the condensate tray according Step 2;
- Check the O-ring (9) of the cup and replace if necessary;
- Clean the parts by
fl
ushing it with clean water;
- Grease the O-ring again with acid free O-ring grease to make
fi
tting easier;
- If there is a leak at the condensate trap (8) replace complete condensate trap by
# 809000100;
Step 2: Condensate tray
- Remove the plug from the
fl
ue gas sensor if present;
- Turn the two short clamping rods (11 and 12) ¼ turn and remove them by pulling
them forward; Note the right turning direction (red indicator);
- Lift the exhaust pipe (13) out of the condensate tray (14);
- Press the condensate tray (14) carefully downwards and remove it by pulling it
forward;
- Replace the gasket between condensate tray and heat exchanger with a new one;
- Clean the condensate tray with water and a hard brush;
- Check the condensate tray for leaks.
Step 3:
Re
fi
tting is done in reverse order.
Note that all gaskets seals completely.
Make sure that during refi tting the clamping rods they are put in the right
position. They should be turned vertical.
If the boiler should activate with clamping rods in the wrong position it will
cause property damage, personal injury or loss of life.
Put the boiler into operation and check the O
2
