Installing a Wood Stove Chimney in a Cathedral Ceiling: A Technical Guide

Installing a wood stove in a room with a cathedral ceiling can be an efficient and visually striking choice. However, the process of setting up the chimney for such an installation requires careful consideration and technical know-how. In this article, we’ll provide a clear and concise guide on installing a wood stove chimney in a cathedral ceiling.

1. Pre-Installation Planning

Before you begin, there are several essential considerations to take into account:

1.1. Local Regulations: Check your local building codes and regulations to ensure compliance with chimney height, clearances, and safety requirements.

1.2. Chimney Type: Choose between a factory-built chimney system or a masonry chimney. Factory-built chimneys are often more suitable for cathedral ceiling installations due to their lightweight and flexible design.

1.3. Chimney Design: Select a chimney design that complements your cathedral ceiling while providing proper draft and performance.

2. Assembly of Chimney Components

When assembling the chimney components, follow these steps:

2.1. Chimney Sections: Assemble the chimney sections per the manufacturer’s instructions. Ensure that they are securely connected and fastened according to the recommended clearances.

2.2. Support Box: Install a support box to secure the chimney as it passes through the ceiling. The support box should maintain clearances specified in the installation manual.

2.3. Roof Flashing: Properly install the roof flashing to ensure a watertight seal. Flashing will prevent water from entering the ceiling and damaging the structure.

3. Cutting the Ceiling and Roof

Cutting an opening in the cathedral ceiling and roof is necessary to accommodate the chimney. Here’s how:

3.1. Marking the Hole: Measure and mark the precise location for the chimney penetration on the ceiling and the roof.

3.2. Ceiling Cut: Cut a hole in the ceiling using a reciprocating saw or a similar tool. Ensure that the cut is neatly aligned with the chimney’s support box.

3.3. Roof Cut: On the roof, cut a hole using a reciprocating saw or a circular saw equipped with a metal-cutting blade. Be cautious when working on the roof, using appropriate safety measures.

4. Roof Flashing and Storm Collar Installation

Once the roof cut is made, follow these steps:

4.1. Flashing Installation: Slide the roof flashing down over the chimney pipe until it is seated on the roof. Ensure that it is properly centered and secure.

4.2. Storm Collar: Install a storm collar around the chimney pipe above the flashing to provide an extra weatherproof seal.

5. Exterior Chimney and Cap

5.1. Chimney Height: Extend the chimney above the roofline to the appropriate height, which will depend on your local regulations and the chimney’s design.

5.2. Chimney Cap: Install a chimney cap on top of the chimney to prevent rain, debris, and animals from entering.

6. Interior Finishing

In the interior, you can use finishing materials around the ceiling penetration, such as a decorative collar or heat shield, to ensure a clean and attractive appearance.

7. Professional Inspection

Always consider having a professional chimney installer inspect the installation to verify compliance with safety standards and to ensure that everything is correctly positioned and sealed.

Conclusion

Installing a wood stove chimney in a cathedral ceiling requires careful planning, precise execution, and compliance with local regulations. Following the steps outlined in this guide will help you achieve a safe and efficient wood stove installation that not only provides warmth but also enhances the aesthetics of your space.
