Recommended minimum service clearances
For typical Viessmann AirflowPLUS installation, it
is recommended to install the air handler with the
clearances shown in the illustration.
a - 24 in. (610 mm)
b - 12 in. (305 mm)
These dimensions reflect the recommended service
clearance for the air handler only, ensure adequate clearance
is left for the installation of ducting, piping and electrical
connections. Only the b clearance may be reduced providing
there is enough clearance for ductwork, plumbing and
electrical connections, with zero clearance between the air
handler unit and ducting being acceptable.
