4.3 Connecting the off-heat duct
The off-heat duct supplied enables a controlled discharge of warmed air,
which allows the device to be operated even in confined spaces.
1. Supply air,
at least ø 10 cm/3,95 in
2. Exhaust air
3. Exhaust gas
The off-heat of the heat exchanger needs
to be conducted from the installation space
to the outside sideways or downwards in a
ø 10 cm/3.95 in duct.
The supply air side must not be guided by a
duct to ensure that the installation space is
well ventilated.
1. Sink the screws for the off-heat
flange into the holes provided at the
air outlet of the EFOY Pro fuel cell.
2. Attach the off-heat bow to the off-
heat flange.
Use the off-heat bow to conduct
warm air sideways or downwards. If
you do not need the off-heat bow,
you can connect the off-heat tube di-
rectly to the off-heat flange.
