Clearance Requirements
The top, back, and sides of the heater are defined by
stand-offs.
The minimum clearance to a perpendicular wall
extending past the face of the heater is one inch (25
mm).
For 6000 Series Models, the back of the heater may
be recessed 21-1/2 inches (546 mm) into combustible
construction.
