Condensate trap and condensate tray (figure 30-32) (2 and 4 year maintenance)
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 flushing it with clean water;
- grease the O-ring again with acid free O-ring grease to make fitting easier;
- if there is a leak at the condensate trap (8) replace complete condensate trap by
S4421200;
Step 2: Condensate tray
- remove the plug from the flue 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 by a new one;
- clean the condensate tray with water and a hard brush;
- check the condensate tray on leaks.
Step 3: Refitting is done in reverse order.
Note that all gaskets seals completely.
Make sure that during refitting the clamping rods they are put in the right
position. They should be turned vertical.
If the boiler should activated with clamping rods in the wrong position it will
cause serious property damage, personal injury or loss of life.
Put the boiler into operation and check the O
2
(see page 50).
If replacement by new gaskets and burner mentioned in this chapter is not done
within the service interval subscribed by Rinnai the boiler can be damaged and
will cause serious property damage, personal injury or loss of life.
Use only original spare parts supplied by Rinnai. If other parts will be used
the boiler can be damaged and will cause serious property damage, personal
injury or loss of life. Use of non-Rinnai parts will result in the void of warranty.
