BLOWER
COIL UNIT
Cut an opening appropriately sized for combustible base.
Base dimensions are shown in figure 15. After opening
has been cut, set the additive base into opening. Connect
outlet air plenum to the additive base. Set the unit on the
additive base so flanges of the unit drop into the base
opening and seal against the insulation strips. Seal
around the insulation strips with permagum. The unit is
now locked in place. Install return air plenum and secure
with sheet metal screws.

3– If hanging the unit, it must be supported along the
entire length of the cabinet. If using chain or strap,
use a piece of angle iron or sheet metal attached to
the unit (either above or below) so that the full
length of the cabinet is supported. Use securing
screws no longer than 1/2” (13mm) to avoid dam-
age to coil or filter. See figure 17. Connect return
and supply air plenums as required using sheet
metal screws.
