HOOD EXHAUST

NOTE: Read these next two pages only if you plan to vent your exhaust to the outside. If you plan to recirculate the air back into the room, proceed to page 6.

OUTSIDE TOP EXHAUST (EXAMPLE ONLY)

The following chart describes an example of one possible ductwork installation.

		EQUIVALENT		NUMBER		EQUIVALENT
DUCT PIECES		LENGTH	x	USED	=	LENGTH
	Roof Cap	24 Ft.	x	(1)	=	24 Ft.
	12 Ft. Straight Duct	12 Ft.	x	(1)	=	12 Ft.
	(6″ Round)
	Rectangular-to-Round	5 Ft.	x	(1)	=	5 Ft.
	Transition Adaptor*
Equivalent lengths of duct pieces are based on actual tests and
reflect requirements for good venting performance with any vent hood.				Total Length	=	41 Ft.

*IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have to be cut to fit, using the tin snips, in order to allow free movement of the damper.

OUTSIDE BACK EXHAUST (EXAMPLE ONLY)

The following chart describes an example of one possible ductwork installation.

		EQUIVALENT		NUMBER		EQUIVALENT
DUCT PIECES		LENGTH*	x	USED	=	LENGTH
	Wall Cap	40 Ft.	x	(1)	=	40 Ft.
	3 Ft. Straight Duct	3 Ft.	x	(1)	=	3 Ft.
	(31⁄4″ x 10″ Rectangular)
	90° Elbow	10 Ft.	x	(2)	=	20 Ft.
Equivalent lengths of duct pieces are based on actual tests and
reflect requirements for good venting performance with any vent hood.				Total Length	=	63 Ft.

NOTE: For back exhaust, care should be taken to align exhaust with space between studs, or wall should be prepared at the time it is constructed by leaving enough space between the wall studs to accommodate exhaust.
