Use only factory supplied components. Failure to

do so will void the certification and the warranty of

the chimney system.

EFFECTIVE LENGTH AND MATERIAL

THICKNESS

The effective length is the length of the part when it is

assembled.

Effective Length Thickness for 5" to 36" diameters

L36 = 36-1/8"

L24 = 24-1/8"

L18 = 17-5/8"

L12 = 11-5/8"

CLEARANCE TO COMBUSTIBLE NON -

FIRE RATED UL 1978 LISTING

APPLICATION

Model DAS1, DIS1, DIS2, DIS4 and DIS3Z 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

CIXPRO SERIES FOR GREASE DUCT UL1978 SUBMITTAL RECORD

Material

inner wall = 0.035"

outer wall = 0.024"

Model DCL) or the Outer Band BSE (for Model

DAS1, DIS1, DIS2, DIS4 and DIS3Z). See Figure 1

for the clearance distance.

For fire resistive non-combustible enclosure 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,

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 DCL, DAS1, DIS1, DIS2, DIS4 and DIS3Z

chimneys may penetrate a combustible floor, wall, or roof using

the appropriate parts and openings sizes.

NOTE: Model DIS3Z is equivalent to a 2-Hr fire rated

grease duct enclosure system.

NOTE: Do not completely enclose the chimney with

combustible materials.

In the case of a fire rated enclosure made of non-combustible

or limited combustible construction, the minimum clearance

for Model DCL is 6" or as required by local code.

Model DIS3Z can be used for either combustible or non-

combustible surroundings. When installed in an open room

where enclosure is not required, the duct may be located at a

minimum clearance to adjacent combustible walls
