Material Type
Use only factory-supplied components. Failure to do so will void the
certification and the warranty of the grease duct system.
EFFECTIVE LENGTH
The effective length is the length of the part when it is assembled.

CLEARANCE
DuraVent Models D C L , D A S - P R O a n d D I S - P R O are primarily intended to be
used in a non-combustible surrounding. Only Models DAS-PRO and DIS-PRO can
be used for either combustible or non-combustible surroundings. When installed
in an open room where enclosure is not required, the chimney may be located
at a minimum clearance to adjacent combustible walls in accordance with Table
1. The chimney may be located in corners formed by two combustible
constructions (walls, floor, ceiling, supports, etc.)
NOTE: The clearance distance with the wall is the distance between the wall and
the inner V-Band for model DCL or the Outer Band (BSE) for model DAS-PRO and
DIS-PRO. See
Table 1
for the clearance distance.
For non-combustible construction, maintain clearance as required for installation
access for inspection or per local code. In buildings more than one story in height
and in one-story buildings where the roof-ceiling assembly is required to have a fire
resistance rating, the duct must be enclosed in a continuous enclosure from the
lowest fire-rated ceiling or floor above the hood, through any concealed spaces,
to or through the roof to maintain the integrity of the fire separations required
by the applicable building code provisions. If the building is less than 4 stories
in height, the enclosure shall have a fire resistance rating of not less than 1
hour. If the building is 4 stories or more in height, the enclosure shall have a fire
resistance rating not less than 2 hours.
DuraVent models DAS-PRO and D I S -PRO chimneys may penetrate a combustible
floor, wall, or roof using the appropriate parts and openings sizes. See Section D
“Roof and Wall Penetration” for more details.
NOTE: Do not enclose with combustible materials
In the case of a fire rated enclosure made of non-combustible or limited
combustible construction, the minimum clearance with the Model
D
CL must
be 6” or as required by local code.
