Before You Begin: Allow any fire to burn out and the stove to become cold. Clean the ashes out of the firebox by placing them into a covered noncombustible container made for this purpose.
1. Using a 5/16” socket or wrench, remove the bolt that holds the secondary air pipe in place. This bolt is located on the far left side of the secondary air pipe, going through the primary air upright.
2. Push the air pipe to the right and remove it by pulling it through the side door. If the pipe has distorted to a point where this is not possible, cut it into 2 pieces using a hack saw or hand grinder and remove the 2 halves.
3. Before installing the new pipe, remove the side plate. To do this, use a 3/8” wrench to remove the bolts in the bottom tabs that hold it to the right side air channel.
4. Clean any loose debris from around the hole in the right side stone with a wire brush.
5. To prepare the new pipe, locate the threaded hole on one end of the pipe. Turn the new self-tapping bolt into the pipe to insure the threads are good. Remove the bolt. Using a disposable rubber glove, apply enough cement to this end of the pipe to seal it. This will
help insure that air coming through the pipe is introduced through the ¼” holes that are drilled for this purpose.
6. Place the pipe back into the stove and secure it with the self-tapping screw. Seal the right side of the pipe on the inside of the stove using a rubber glove and more of the stove cement.
7. Replace the right side plate and secure it by reinserting the bolts through bottom tabs.
8. Allow 24 hours before burning to allow the stove cement to cure.
