7. Remove outside mounting plate with tube attached from wall.
Mark and cut the extra length of the 6 5/8” (168mm) diameter
tube from the opposite end. Do not crimp or enlarge tube.
8. Attach the 4” (102mm) diameter flue outlet tube onto the rigid
venting system or directly to fireplace. Ensure the 4” (102mm)
diameter flue outlet tube is placed as far as possible onto the
rigid venting system. Mark the 4” (102mm) diameter flue outlet
tube 2 1/2” (64mm) beyond the vinyl siding kit or wall. S

points to help in making a true cut. Do not crimp or enlarge
tubes.
10. From outside: Push the 6 5/8” (168mm) diameter inlet tube/
mounting plate onto end of rigid venting system to correct posi-
tion. Fasten the outside mounting plate to the vinyl siding kit or
wall with 10 x 1 1/2” screws. (Ensure upward slope).

fireplace (or the rigid venting system) using three self tapping
screws.

perpendicular “rocking” motion. This ensures the seam on the
tube stay intact.
