15, and 16
Option CW 13, 14, 15, and 16 return air filter cabinets are shipped factory assembled.
Position the filter cabinet in its final location being careful to allow sufficient clearance
on the filter access side.
After the filter cabinet is secure, set the Model CAUA on
the filter cabinet. (
NOTE: Be sure hole has been cut in bottom of CAUA before placing
it on the filter cabinet; see Installation Preparation on page 11.) The filter cabinet is
designed so that there is no mechanical attachment required between the filter cabinet
and the heater.
Attach return air duct to the duct flange on the bottom of the filter cabinet; see dimen-
sions in
FIGURE 10. This completes installation of a bottom filter cabinet.
Sizes of field-supplied or replacement filters are listed in the component table on page

After heater installation is complete, turn on the electric and the gas and check for
proper operation.
