13a. If changing from horizontal discharge
to vertical (such as front/top to top/
front) then a duct extension will need
to be added to join the fan to the roof.
b. On units without internal isolation the
duct extension is secured to the fan
housing with screws. The duct can be
purchased from Service Parts or can
be fabricated in the field.
c. On units with internal isolation the
duct extension is wider at the bottom
to form a gap between and the fan
housing, which is bridged by a flexible
foam gasket. Contact Service Parts
for a duct extension kit. (See Fig. 1)
14a. If changing from vertical to horizontal
(such as top/front to front/top) then
the duct extension will need to be
replaced by mounting angles to join
the fan to the cabinet.

Installation
b. On units without internal isolation the
mounting angles can be secured to
the fan and to the cabinet with
screws. The angles can be purchased
from Service Parts or can be
fabricated in the field.
c. On units with internal isolation the
mounting angles do not extend as far
and do not reach the cabinet panel.
The gap is bridged by a flexible foam
gasket. Also the gasket stays
compressed using a thrust restraint
assembly. Contact Service parts for
angle/gasket kit. (See Fig. 2)
