6.5 Condensation drain pipe
Rinnai boilers produce condensate. This condensate must be drained otherwise the
boiler will not function.
The condensation drain pipe must be piped via a tundish because it is also the pressure
relief valve drainage. If it is then piped into a drain or soil pipe it must be trapped after the
tundish to prevent smells from entering the room. The drain connection should have a
minimum diameter of 32mm.
Connect the condensation drain pipe according to the actual regulations.
The following components are connected to the collective condensation drain pipe:
- Condensation discharge;
- Safety valve;
Draining of the condensation water to the external rain guttering is not
permitted in view of the danger of freezing.
Before putting the boiler into operation fill the siphon with 300 ml of water.
The condensate pipe must be run using suitable corrosion resistant materials (eg. PVC,
uPVC, or ABS pipe) . Copper and steel are not recommended.
