Condensate spillover
The condensate drain is located on the side of the water heater.
This is where you can connect a drain hose.
When installing the unit outdoors, the condensate can drain off
freely.
For indoor installation, the condensate can be routed into a floor
drain or routed through the wall up to 889 mm (35") (see diagram
above).
If required, install a condensate pump.
To ensure the condensate drains correctly, never kink
the hose.
