Locating Wall Opening
The furnace is to be located on an outside wall. Locate wall studs so
that wall opening will be located between wall studs. The furnace
is 16 inches in width and normal 16 inches on center studs will

repositioned. The wall opening required as shown in Figure 5 is
a diameter of 7 1/2 inches.
A template is provided in furnace carton for positioning furnace
on the wall. Also, refer to Figure 5 for positioning the furnace on
wall and for locating gas line connection.
