Measure the roof pitch.
How high above hip roof should duravent stove pipe be.
Measure the roof pitch.
Minimum chimney height at sea level of straight vertical chimney is 10 to 15 above the appliance outlet.
Hopefully this will be enough.
If the pipe is farther than 10 feet from the roof peak.
Select the proper flashing and storm collar.
Subtract 1 1 4 per joint of durablack stovepipe.
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 specification makes sure steep roof slopes are cleared.
This will bring the total height of the pipe not including the cap to 85 inches.
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.
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.
For horizontal installations check the appliance manufacturer s instructions for minimum rise and maximum horizontal run.
First you ll need to know the pitch of your roof.
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.
Building codes require a minimum of 3 above the roof penetration and at least 2 higher than any portion of a building within 10.
Determine the number of chimney pipe lengths required.
If chimney is more than 4 above the roof penetration an extended roof bracket is required.
For gas vents or a type l vent this distance above the roof surface must be at least 2 ft 0 61m.
The termination cap is installed above that point.
Subtract 1 1 2 per joint of dvl stovepipe.
The termination cap is installed above this point.
The extended roof bracket consists of the pipe band the adjustable legs and the roof brackets.
Vertical blue line along the left side of the chimney in our photo.
Determine the minimum height above the roof.
In the photo below you can see where the braces currently attach 41 inches above the collar.
