Unit Heater Discharge Duct Guidelines
A field-fabricated and installed discharge air duct and grille
cabinet is suitable for use with the G61MPV heater. See fig-
ure 22. Keep the following items in mind when constructing
the cabinet,
1 - Outer dimensions of cabinet should match those of the
unit heater, so the duct/grille cabinet installs flush with
the unit heater cabinet, See figure 22,
2 - Flange both ends of duct/grille cabinet so that screws
can be used to secure cabinet to discharge end of unit
heater,
