DGX Industrial Space Heating
Installation of Indoor Unit
3. Seal Wall Opening
Apply sealant around the perimeter of the weatherhood
to prevent water penetration and drafts into the building.
1. Install Hangers
Install threaded hangers from ceiling supports. When
locating hangers, allow enough room to open access
panel(s). Be sure to allow for the recommended diffuser
height outlined in the Diffuser installation section,
page 6. Two nuts must be used on the end of each
threaded hanger. Ceiling supports are supplied by
others. Refer to diagram below.
2. Install Unit
Using sheet metal screws, attach the weatherhood/
thru-wall/filter section to the blower/burner section.
The flange on the weatherhood/thru-wall/filter section
should overlap the flange on the blower/burner section.
Raise the assembled unit into place.
Using two nuts per hanger, fasten the unit supports to
the hangers under the unit. Appropriate unit supports,
such as the optional manufacturer hanging bracket kit,
or c-channel and angle iron (supplied by others), should
be used. Refer to the Indoor Mounting drawing.
In order to prevent the unit from swinging and to provide
a safe environment for service and maintenance,
additional measures must be taken to secure the unit in
all directions.
NOTE
Two nuts must be used on each end of each threaded
hanging rod for proper support.
NOTE
Good duct practices should be followed for all
ductwork. Ductwork should be installed in accordance
with SMACNA and AMCA guidelines, NFPA 96 and
any local codes. Reference the CAPS submittal for
duct sizes.
