Installation Guide for DuraPlus Attic Offset Chimney Pipe Kit

The DuraPlus Attic Offset Chimney Pipe Kit is designed to simplify your installation process while ensuring that your chimney operates at its best. Follow these steps for a seamless setup that prioritizes safety and effectiveness. The DuraPlus Attic Offset Kit is available in 6-Inches, 7-Inches and 8-Inches.

1. Position the Appliance: Place your appliance according to the manufacturer’s instructions, ensuring the flue outlet collar is between the rafters or joists above.
2. Frame the Support Opening: Use a plumb bob to mark the center point of the appliance’s flue outlet on the ceiling.
   Refer to Table 2 for framing and clearance dimensions, then cut a square or round hole based on the type of support box you will use. Frame a level opening above the hole.
3. Install the Support Box: Insert the support box into the framed opening, making sure it extends at least 2 inches below the finished ceiling.
   Level it and secure it with two 8-penny nails per side. Attach trim frames for a neat finish.
4. Frame Openings for Shields: Frame additional openings in each ceiling or floor above the support box for the Firestop Radiation Shields and Attic Insulation Shields.
   Drop a plumb bob for alignment, and follow Table 2 for measurements. If you need to change direction, use elbows to create an offset.
5. Cut the Roof Opening: Cut an opening in the roof above the framed area, ensuring at least a 2-inch clearance around the chimney.
   If your rafters are 16 inches apart, you can use Close Clearance Shields to simplify the framing.
6. Install Firestop Radiation Shield: Install the Firestop Radiation Shield based on whether it’s a two-story or multi-story building.
   Nail the base to the framing and ensure the pan is facing the right direction.
7. Assemble Chimney Sections: Lower the first chimney section into the support box and twist-lock it to the starter section. Make sure it’s secure. Use screws only if necessary.
8. Install the Attic Insulation Shield: Install the Attic Insulation Shield where the chimney passes into the attic to keep debris away. If the shield won’t fit, use a square support box instead.
9. Attach Flashing: For new builds, extend the chimney above the roof and slide the flashing over it. For existing roofs, center the flashing first. Maintain a 2-inch clearance and seal nail heads for weatherproofing.
10. Finish the Top: Seal around the chimney where the storm collar meets the flashing and secure the collar. After adding enough chimney sections, attach the chimney cap.
11. Enclose the Chimney: Enclose the chimney wherever it passes through living spaces, keeping a 2-inch clearance from any combustible materials.

Following these steps will help you safely and efficiently install your attic offset chimney pipe kit. Trust DuraVent for quality and safety in your chimney system!
 

Easy Steps for Installing DuraPlus Elbows

1. Attach the Elbows

   • Twist to Lock: Connect the Elbows to the Chimney Sections by twisting them clockwise until they lock in place. Start with one Elbow on the Chimney Section below, making sure it’s aligned correctly.
   • Adjust Direction: If the Elbow needs to face a different way, rotate it to the desired direction. Use at least four sheet metal screws to secure it, but don’t drill through the inner wall.
   • Check Offset Length: Look at Table 3 to find the right offset lengths. Attach the correct length of Chimney Sections above the Elbow, and don’t go over the maximum lengths in Table 3. Finally, add the second Elbow above the Chimney Section.

2. Secure the Offset

   • Use an Elbow Strap: Place the Elbow Strap around the top Elbow and tighten it until it feels secure.
   • Nail It Down: Wrap the end of the strap over a nearby joist or rafter and secure it with at least two 8-penny nails.
   • Support Before Adding More: Don’t add more Chimney Sections until the Elbows are supported. Make sure the chimney stays vertical. If the length between the two Elbows is over three feet, install a second Elbow Strap around the center of the Chimney Section(s) for extra support
