How High Above Hip Roof Should Duravent Stove Pipe Be

If chimney is more than 4 above the roof penetration an extended roof bracket is required.

How high above hip roof should duravent stove pipe be.

The termination cap is installed above that point. For gas vents or a type l vent this distance above the roof surface must be at least 2 ft 0 61m. Vertical blue line along the left side of the chimney in our photo. The top of the chimney should be at least 3 ft 0 92 m above the roof surface.

Currently the pipe is 6 inches above the roof peak. The chimney must extend at least 3 feet above the highest point where it passes through the roof and be at least 2 foot higher than any part of the building within a horizontal distance of 10 feet figure 2. In the photo below you can see where the braces currently attach 41 inches above the collar. Also you ll need the horizontal distance between the peak and the edge of the high side of the pipe see figure 1 where you plan your roof penetration.

Roof pitch is easily calculated and if you don t know how read my article understanding and calculating roof pitch. The extended roof bracket consists of the pipe band the adjustable legs and the roof brackets. To calculate the installed per length of 6 8 duraplus chimney pipe subtract 1 1 2 per joint. Building codes require a minimum of 3 above the roof penetration and at least 2 higher than any portion of a building within 10.

Distance matters the top of a chimney pipe must extend at least 2 feet above the peak of the roof if the pipe is within 10 feet of the peak. Minimum chimney height at sea level of straight vertical chimney is 10 to 15 above the appliance outlet. Measure the roof pitch. If the pipe is farther than 10 feet from the roof peak.

For horizontal installations check the appliance manufacturer s instructions for minimum rise and maximum horizontal run. The termination cap is installed above this point. Subtract 1 1 4 per joint of durablack stovepipe. Measure the roof pitch.

Subtract 1 1 2 per joint of dvl stovepipe. This will bring the total height of the pipe not including the cap to 85 inches. If the chimney extends more than 5 above the roofline an extended roof bracket must be installed at every 5 increment of chimney height above the roofline leaving no more than 5 of chimney extending above the last pipe bracket. Select the proper flashing and storm collar.

Hopefully this will be enough. Determine the minimum height above the roof. Determine the number of chimney pipe lengths required.
