INSTALLATION OPTIONS

Roof Mounted Installation

Model DGX is available for stand alone installations as shown below. Downblast (Arrangement DB), upblast (Arrangement UB), or horizontal (Arrangement HZ) discharge may be specified.

Upblast Discharge - Arrangement UB

Horizontal Discharge - Arrangement HZ

 

The Greenheck combination package simplifies installation and reduces field labor costs. The pre-engineered design ensures that the supply fan, exhaust fan, curb, and combination extension components interface properly for kitchen ventilation applications.

Equally important, Greenheck combination packages are specifically designed to comply with NFPA 96.

NFPA 96 states:

Exhaust duct must terminate at least 24 inches above the roof deck

Fan discharge must be at least 40 inches above the roof deck

Air intake shall have a horizontal separation of 10 feet from the exhaust discharge

Note: Consult local codes and the authority having jurisdiction if there are questions concerning the use of this product.

Combination Package - Arrangement DBC

The combination curb extension is the component that pulls the Combination Package together, providing a factory engineered interface between the roof curb and the fans. It is also designed to satisfy NFPA 96 requirements - above the roof line - for kitchen hood exhaust.

Thru-Wall Installation

Model DGX (Housing 12, 22, & 32 only) is available with a pre-engineered thru-wall installation option, which is ideal when a roof penetration is not desirable.

Factory options that facilitate easy installation and ensure problem-free operation:

Weatherhood: A full down turn design with generous intake area to minimize intake velocity and moisture entrainment.

Thru-Wall Sleeve: Sleeve provides attachment interface between weatherhood and burner section. Accommodates walls up to 15 inches in depth.

Filter Section: Aluminum mesh media filters outdoor air and strips fine mist from the air. A drain pan weeps moisture out the front of the wall sleeve.
