Locate the chimney flue opening for the wood stove. Remove any wall materials within 2 inches of the 8-inch opening for the Ashley stove pipe, using a reciprocating saw. Building codes require a 2-inch air space between the wall and the thimble.
Screw the metal wall guard in place along the edge of the opening. Use a level to ensure the plate sits straight in the opening.
Apply a generous bead of high temperature furnace cement to the end of the thimble. Slide the clay thimble through the wall guard against the wall of the chimney and press firmly to make good contact. Allow to dry for at least eight hours.
Locate the Ashley stove as close to the chimney as possible. The limit for the amount of stove pipe to the chimney wall is 10 feet. Apply a bead of high temperature furnace cement to the inside of the male end of a section of the 8-inch stove pipe. Slide the first section of pipe over the opening at the back of the stove.
Apply a bead of the furnace cement to the inside male end of a 90-degree pipe elbow. Slide the elbow in position over the pipe opening coming from the Ashley stove.
Add a vertical section of stove pipe to reach from the elbow to 8 inches below the height of the thimble opening. Cement the male end in place as in the previous section.
Add another 90-degree elbow to make the turn from the vertical pipe towards the chimney. Cement in place.
Slide one or two sections of stove pipe to connect the elbow with the chimney, depending on the distance between the Ashley stove and the chimney. Cement into place. Do not cement the chimney end of the pipe into the thimble, just slide it in place.
Allow the cement to dry for 24 hours. Screw the stove pipe to the Ashley stove through the holes on the stove. Screw three 1/2-inch self-tapping steel screws into the overlap of each section of stove pipe, including the elbows.
