Wall Thimble (3) is essential for through-the-wall installations, creating a safe passage for the chimney.
Tee with Cap (11) allows for easy cleaning and inspection.
Tee Support Bracket (12) provides additional support for the tee section.
Wall Strap (13) secures the chimney to the exterior wall.
Chase Top Flashing (20) provides a weather-tight seal around the chimney penetration when enclosed in a chase.
3. Offsets and Elbows:
Determine if offsets are necessary to avoid obstacles.
Use either 15° or 30° elbows (9) strategically; elbows greater than 30° are not allowed in the United States.
Elbow Straps (10) are required for each offset to ensure proper support.
4. Additional Components:
Attic Insulation Shield (5) must be used in all installations passing through an attic.

DuraPlus by Duravent is a versatile chimney system designed to accommodate a wide range of fuel types
Clearances:
Clearance to Combustibles: Maintain a minimum clearance of 2 inches to combustible materials for DuraPlus by Duravent. This ensures safe operation and prevents potential fire hazards. Measure and adhere to this clearance requirement during installation.
Cavity Measurements:
Through-the-Roof Installation:
When penetrating the ceiling with a Ceiling Support Box (2), ensure proper measurements for a secure fit. Measure the thickness of the ceiling material and select the appropriate Ceiling Support Box.
Use the Roof Flashing (6) to create a weather-tight seal around the chimney penetration. Measure the roof pitch and choose the correct flashing for a proper fit.
Install the Storm Collar (7) snugly around the chimney above the flashing to prevent water leakage.
For an extended chimney above the roof line, measure and install the Extended Roof Bracket (16) if the chimney extends more than 4 feet.
Through-the-Wall Installation:
Use the Wall Thimble (3) for a safe passage through the wall. Measure the wall thickness to determine if a wall thimble extension is needed for thicker walls.
Measure and plan for the Tee with Cap (11), Tee Support Bracket (12), and Wall Straps (13) to support and secure the chimney on the exterior wall.
If the chimney is enclosed in a chase in the attic space, measure for the Chase Top Flashing (20) to create a weather-tight seal.
Offsets and Elbows:
When offsets are necessary, measure the horizontal distance required and the vertical height available. Select 15° or 30° elbows (9) as needed. Ensure measurements comply with regulations, and use Elbow Straps (10) for support.
Do not use elbows greater than 30° in the United States. Refer to the offset table in the installation instructions for guidance.
