Applications
Tranquility Cased coils can be applied in upflow, downflow,
horizontal right and horizontal left applications without
modifications. For horizontal applications, installation of an
auxiliary/secondary drain pan is required. For coils that are
two sizes larger than the furnace, for example, a 21” [53.3
cm] wide coil on a 14” [35.6 cm] furnace, a tapered adaptor
with a minimum height of 6” [15.2 cm] is required to evenly
distribute airflow. See Figure 3. For coils that are one size
larger than the furnace; for example a 21” [53.3 cm] wide coil
on a 171⁄2” [44.5 cm] furnace, seal the gap between the two
units with sheet metal. See figure 4.
�
CAUTION!
�
CAUTION!
For horizontal applications, the horizontal
drain pan must be located under the indoor coil. Failure
to place the pan under the coil can result in property
damage.

Table 3: Coil Application
*Due to the proximity of the drain pan to the high
temperature oil furnace drum, horizontal left application is
NOT permitted on oil furnaces.
