How to Install a DuraTech Chimney Pipe Kit with a Ceiling Support Box?

For a safe, secure, and efficient chimney installation, the Support Box is a crucial component. Whether you’re using a Square Ceiling Support Box or a Reduced Clearance Support Box, ensure that it extends at least 2 inches below the lowest point of the finished ceiling (Figure A). This is vital for proper support and clearance. The Support Box must also remain level and the top edge must cover the roof's decking. Note that all mobile home chimney installations must be roof-supported. The DuraTech Ceiling Support Box Kit is available in 6-Inches, 7-Inches and 8-Inches.

1. Position the Appliance: Set up the appliance according to the manufacturer's instructions, aligning the flue outlet between rafters or joists if possible.
2. Cut Openings: Make an opening in the ceiling with 2 inches of space around the chimney pipe. The opening should be circular or oval for the Trim Collar to fit properly.
3. Install the Support Box: 
   • Insert the Support Box into the opening so it extends at least 2 inches below the ceiling.
   • Level the box and secure it to the roof framing with three nails or screws per side.
   • Attach the trim sections to the ceiling.
4. Assemble Chimney Sections: Insert the first chimney section into the Support Box and twist-lock it in place. Use short screws (if needed) to secure the connection, but do not penetrate the inner liner.
5. Install the Spray Foam Insulation Shield: Install it like the Support Box but use only one nail or screw per side.
6. Attach Flashing: 
   • For new roofs, slide the Flashing over the chimney after assembling the chimney sections.
   • For existing roofs, install the Flashing before extending the chimney. Ensure the chimney is straight and has 2 inches of clearance from combustibles.
   • Secure and seal the Flashing properly with roofing nails and sealant.

Following these simple steps will help ensure a secure and efficient chimney installation.
