WARNINGS
DO NOT INSTALL ANY TYPE OF INSULATION IN THE
REQUIRED CLEARANCE SPACES SURROUNDING
THE CHIMNEY.
OPENING THROUGH COMBUSTIBLE CONSTRUCTION
The following table serves to identify the minimum opening required when
installing a chimney through a floor, wall or roof made of combustible
material. See table 3 and figure 1.

PART NUMBERS
These instructions identify major model DIS / DAS parts by name and
part number.
Example:
DIS 36” length with inside diameter 14” made of ss316 inner flue and
ss304 outer casing.
DIS 14 L36 BC
Model Dia. Part Material
DAS 30° elbow with inside diameter 22” made of ss304 inner flue and
galvalume outer casing.
DAS 22 E30 CE
Model Dia. Part Material
DIS wall support for 8” diameter chimney made of galvalume.
DIS 8 WS E
Model Dia. Part Material
Use only factory-supplied components. Failure to do so will
void the certification and the warranty of the chimney system.
EFFECTIVE LENGTH
DIS / DAS
When assembling two parts together, the joint will overlap 5/8”. So ef-
fective length is nominal length minus 5/8”
