INTRODUCTION
The CK3B is a horizontal, multi-use cased fumace coil. (See Fig. 1.) With the use of field-supplied transition duct, these furnace coils can also
be applied to other similar horizontal furnaces on the market. The CK3B is available in sizes 024 through 060. (See Fig. 2.)
NOTE:

Models with tin-plated copper coils ("T" in the 10th position of the model number) are installed the same as standard copper coils.

NOTE:
If unit is located in or above a living space where damage may result form condensate
overflow,
a field-supplied,

pan should be installed under the entire unit, and a secondary
condensate
line (with appropriate
trap) should be run fl:om unit into pan. Any
condensate
in this external condensate
pan should be drained to a noticeable place. As an alternative
to using an external condensate
pan, some
localities may allow the running of a separate 3/4 in. condensate
line (with appropriate
trap) to a place where condensate
will be noticeable.
