Residential Sizing: The table and charts are intended to be used as a guideline for Residential applications only.

The information is based on conventional window space (<15%), insulation and building construction (8 ft.

ceiling height). When including a finished basement, use 1/2 of the finished basement square footage with

the rest of the area being calculated.

Mobile/Manufactured Home Sizing: Refer to the Date Plate located in the electrical box or kitchen cabinets. For

further assistance, call Hamilton's customer service department (800) 879-0123.
