installed recessed with appropriate wall sleeve accessories.
There is no minimum clearance required on locating the

If the unit is installed in a residential garage, it must be located
or protected to avoid physical damage by vehicles. The unit
must be installed so that no electrical components are
exposed to water.
This unit must be installed level to allow for proper
drainage of the unit base pan and indoor drain pan.
