The condensate drain is located in the bottom 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 35"
(see diagram above).
If required, install a condensate pump.
To ensure the condensate drains correctly,
never kink the hose.
10.7 Water connection
The water connection must be carried out by a qualified
licensed plumber.
The cold water connection must comply with DIN1988
[or state and local codes]
» Prior to installing the water heater, flush the line
thoroughly.
