How High Above Hip Roof Should Duravent Stove Pipe Be

Determine the minimum height above the roof.

How high above hip roof should duravent stove pipe be.

For gas vents or a type l vent this distance above the roof surface must be at least 2 ft 0 61m. Measure the roof pitch. Currently the pipe is 6 inches above the roof peak. 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.

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. 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. This specification makes sure steep roof slopes are cleared.

The top of the chimney should be at least 3 ft 0 92 m above the roof surface. Subtract 1 1 4 per joint of durablack stovepipe. Determine the number of chimney pipe lengths required. Roof pitch is easily calculated and if you don t know how read my article understanding and calculating roof pitch.

Vertical blue line along the left side of the chimney in our photo. 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. This will bring the total height of the pipe not including the cap to 85 inches. First you ll need to know the pitch of your roof.

For horizontal installations check the appliance manufacturer s instructions for minimum rise and maximum horizontal run. The termination cap is installed above this point. The termination cap is installed above that point. Building codes require a minimum of 3 above the roof penetration and at least 2 higher than any portion of a building within 10.

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. Select the proper flashing and storm collar. If the pipe is farther than 10 feet from the roof peak. Hopefully this will be enough.

A snorkel termination may be used if height restrictions prevent adequate rise above the appliance. Subtract 1 1 2 per joint of dvl stovepipe. If chimney is more than 4 above the roof penetration an extended roof bracket is required.
