5 Framing and Clearances
A. Selecting Appliance Location
When selecting a location for the appliance it is important to consider the required clearances to walls (see Figure 5.1).
WARNING! Risk of Fire or Burns! Provide adequate clearance around air openings and for service access. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.
