How to install a chimney pipe through the roof.

When installing a chimney for a wood stove on a metal roof you ll first need to assess the position. Place the chimney where it would be related to the stove and mark the center of the chimney on the ceiling. While you re still on the roof attach the storm collar to the chimney pipe. Typically a chimney pipe must terminate at least 3 feet above a roof and the cap must be at least 10 feet from any part of the roof.

Make sure to put a bead of silicone around the storm collar where it meets the chimney pipe. When calculating your chimney pipe size subtract 1 5 inches for each joint overlap. You will need to cut the opening to the roof to extend the chimney pipe. The chimney pipe must protrude through the roof a minimum of 2 feet and it must be at least 10 feet away from the roof line.

Obtain addition sections of stove pipe if necessary. A double wall pipe needs a 12 inch clearance space.
