How High Above Hip Roof Should Duravent Stove Pipe Be

The termination cap is installed above that point.

How high above hip roof should duravent stove pipe be. This will bring the total height of the pipe not including the cap to 85 inches. Subtract 1 1 4 per joint of durablack stovepipe. Select the proper flashing and storm collar. 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.

To calculate the installed per length of 6 8 duraplus chimney pipe subtract 1 1 2 per joint. Subtract 1 1 2 per joint of dvl stovepipe. Measure the roof pitch. Determine the number of chimney pipe lengths required.

First you ll need to know the pitch of your roof. Currently the pipe is 6 inches above the roof peak. If chimney is more than 4 above the roof penetration an extended roof bracket is required. 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.

Vertical blue line along the left side of the chimney in our photo. 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 extended roof bracket consists of the pipe band the adjustable legs and the roof brackets. For gas vents or a type l vent this distance above the roof surface must be at least 2 ft 0 61m.

The top of the chimney should be at least 3 ft 0 92 m above the roof surface. Hopefully this will be enough. 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 pipe is farther than 10 feet from the roof peak.

Measure the roof pitch. A snorkel termination may be used if height restrictions prevent adequate rise above the appliance. Determine the minimum height above the roof. This specification makes sure steep roof slopes are cleared.

Minimum chimney height at sea level of straight vertical chimney is 10 to 15 above the appliance outlet. For horizontal installations check the appliance manufacturer s instructions for minimum rise and maximum horizontal run. The termination cap is installed above this point.
