Condensate connection
Vitodens 100 has within a syphonic condensate trap.
A 722 mm plastic condensate pipe
Routing
The condensate pipe can terminate into any one of the following areas.
It is always the best practice to terminate the condensate pipe via an internal
waste system.
The pipe run should take the shortest practical route with a downward slope of
at least 2.5 ° (4.5 mm/m)
The external pipework should be insulated to prevent freezing
The pipework should terminate as close as possible to the ground or drain,
whilst still allowing the condensate to safely disperse.
The condensate pipe must be of non corrosive material, preferably plastic.
Note: ferrous materials or copper must not be used.
