Service Clearance Recommendations
A minimum clearance of the section width plus 12 inches on the access door side of the gas heat
section is recommended for routine maintenance. This clearance provides enough room to replace
the heat exchanger in the event of failure. The section side panels must be removed to access the
heat exchanger. Refer to
Figure 4
for service clearance recommendations for the air handler.
