Introduction
A ceiling support box, often referred to as a chimney support box, is a critical component when installing a wood stove, especially if it’s located on the upper floors of a building. This box helps support the weight of the chimney pipe, ensuring stability and preventing potential fire hazards. To install it correctly, follow these steps:
Tools and Materials
Before you begin, gather the necessary tools and materials:
- Ceiling Support Box Kit: Purchase a kit that includes the ceiling support box, necessary brackets, and instructions.
- Measuring Tape: For accurate measurements.
- Pencil: To mark precise installation points.
- Screwdriver: For securing screws.
- Stud Finder: To locate ceiling joists.
- Level: To ensure a plumb installation.
- Safety Gear: Including gloves, safety goggles, and a dust mask.
- Firestop Spacer: For fire protection where the chimney penetrates through the ceiling.
Step 1: Prepare the Area
Locate the Ceiling Joists: Use a stud finder to locate the ceiling joists. The ceiling support box must be secured to these joists to ensure its stability.
Measure and Mark: Measure and mark the location for the ceiling support box based on your stove and chimney’s specifications.
Step 2: Install the Ceiling Support Box
Assemble the Box: Follow the manufacturer’s instructions to assemble the ceiling support box, ensuring all components are securely fastened.
Secure to Ceiling Joists: Position the assembled support box over the marked location. Make sure it aligns with the chimney pipe’s route. Secure it to the ceiling joists using the provided screws.
Use a Level: To check that the box is plumb and level, and make adjustments as needed.
Step 3: Install the Chimney Pipe
Connect the Chimney Pipe: Follow the manufacturer’s guidelines for connecting the chimney pipe to the ceiling support box. Ensure a snug and secure fit.
Firestop Spacer: Install a firestop spacer where the chimney pipe penetrates the ceiling. This will help prevent heat transfer and fire hazards.
Step 4: Insulate and Seal
Insulate the Gaps: Fill any gaps around the chimney pipe with non-combustible insulation to ensure the proper draft and prevent heat transfer to nearby structures.
Seal Joints: Seal all joints and connections with high-temperature sealant to prevent any air leaks.
Step 5: Test and Safety Check
Operational Test: Before using the wood stove, perform an operational test. Ensure there are no leaks or unusual noises.
Check Clearances: Verify that the stove and chimney maintain the required clearances from combustibles, as per the stove’s manual and local building codes.
