2.4.1 Installation Clearances
The Benchmark Model 1500 and 2000 are packaged in an enclosure having identical exterior
dimensions. The unit must be installed with the prescribed clearances for service as shown in
Figure 2-1a. The minimum clearance dimensions, required by AERCO, are listed below.
However, if Local Building Codes require additional clearances, these codes shall supersede
AERCO’s requirements. Minimum acceptable clearances required are as follows:
• Sides: 24 inches (61 cm)
• Front: 24 inches (61 cm)
• Rear: 24 inches (61 cm)
• Top: 18 inches (45.7 cm)
All gas piping, water piping and electrical conduit or cable must be arranged so that they do not
interfere with the removal of any panels, or inhibit service or maintenance of the unit.
