Installing a chimney by yourself is going to be an intermediate to expert level type of DIY job. You’ll probably need a partner to do this and make sure that you have the necessary tools and follow the basic safety procedures to get you up and ready for installation.

Make sure that you have:

Step 1

Place the wood stove to where you want to permanently place it inside of your garage. Make sure to ask the manufacturer or a professional one where you can properly place the wood stove to avoid fire hazards or other problems later on.

Step 2

Proceed to measure the wall covering and where you’re going to place the chimney system to penetrate the roof later. Create a circle which is the diameter of the chimney sections to the ceiling using a scribing compass. 

Make sure to add 4 more inches to allow a minimum clearance to allow combustible materials. Adjust the position of the stove to configure any necessary adjustments needed as roof penetration needs to be accurate.

Step 3

Cut the sheetrock of the ceiling with the use of a jab saw or a sharp-bladed knife. Afterward, cut the ceiling hole in order to let the metal chimney collar to pass through. 

Step 4

With the use of a jigsaw or a reciprocating saw, cut the roof sheathing and roofing just outside of the outline of the circle for the stove connection. Make sure to create a proper cut around it to avoid any complications to the installation of the chimney.

Step 5

Prepare the roof for the installation of the chimney collar flashing by clearing away any debris or roofing that may block the installation. Make sure to follow the instructions by the manufacturer and verify the exact location of the hole through the use of a plumb bob.

Step 6

With the use of a framing square and a tape measure, measure the area of the floor that is underneath the woodstove. You will also need to measure the wall line that’s behind the stove where it is in a perpendicular point 2 feet after the front edge of the stove’s door. 

Step 7

Clear the area by moving away from the stove and placing it somewhere safe. You can put it outside the garage or at the opposite side of the room in order to have a much wider workspace.

Step 8

Cover the garage wall where you going to place the stove in with fire-rated sheetrock to protect your wall from any fire hazard. Position it horizontally and centered, and make sure to keep it at least 4ft of distance from the centerline to where the stove is going to be placed in.

Use sheetrock screws and a screwdriver to finish the installation of the sheetrock. Use a drill to predrill the holes into the garage wall if necessary.

Step 9

About 3 feet above and between the centerline area that is marked for the stove, install a full sheet of cement backer. Use board screws and a screwdriver in order to tightly place the wall framing and place them at least 8 inches apart from each wall stud to increase its sturdiness.

Make sure that you don’t extend the cement backer above the end of the fire-rated sheetrock to fire or heat won’t penetrate the bare garage wall.

Step 10

Put back the wood stove into the desired location and check all the measurements to see if it is properly in place. Also, check the clearances to see if it’s in the perfect spot.

Proceed to connect the chimney sections. You can do this by passing the chimney assembly right through the roof opening and collar flashing. Slide the base part over the chimney flange which is located on the stovetop.

You can finish this up by connecting the chimney to the stove flange by checking out the recommended procedure inside the manual.

Step 12

Attach the storm collar just over the roof collar flashing. Continue to run a bead of silicone caulking just around the gap perimeter which is placed between the inside edge of the storm collar and the vertical area of the chimney. 

This is done in order to properly seal the gaps around the chimney to avoid the smoke from leaking inside the room.

Step 13

Attach the chimney cap into the top part of the chimney and make sure that all the cap snaps are properly locked onto the chimney assembly.

On the side of the chimney, there’s going to be a metal handle where you’re going to turn in order to fully open the chimney flue. This is usually located just about 5ft above the stove.

Step 15

Proceed to place wood and paper and use a match to light up the stove. Adjust the chimney flute to get the proper amount of smoke draft that’s going to exit onto the chimney. 

Once you’ve done this then your wood stove chimney is ready to use. 

Conclusion

Once you’ve had your own wood stove, check if there are any safety issues or leaks that may occur. Properly seal them and maintain your stove in order to prevent any kind of hazard from occurring.
