Wood Burning Stove Flue Height Above Flat Roof

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.

Wood burning stove flue height above flat roof.

The roof is in front of two 1st floor windows thanks paula moss 10 2 12. They are of the same modular size as a masonry building block and are usually designed so that. The concrete blocks have an integral narrow rectangular flue way. When installing a new twinwall flue system if the flue exits the roof within 600mm horizontally from the ridge high point of the roof then the flue must extend a minimum of 600mm above the ridge.

How high does the flue have to go. If the flue exits the roof further down then it must extend high enough to acheive 2 3m of horizontal clearance. The minimum chimney height recommended for minimum performance of wood burning and multi fuel appliances is 4 5 m from the top of the appliance to the top of the chimney. If the pipe is farther than 10 feet from the roof.

Chimney height may need to be increased by 2 3 per 1000 feet of elevation although added height generally equates to stronger draft there is a point where the system can become too long and over drafting might occur causing increased fuel consumption hotter burn temperatures and damage to your appliance. What is the minimum height clearance needed for a wood burning stove pipe when exiting a flat roof. They must not be used on a wood burning or multi fuel appliance under any circumstance. The distance between the cowl of the flue and the adjacent roof wall structure should be higher than 2 3 mtr.

Now for the math lesson. The minimum chimney heights above roof are in the article above. This means that below 38 degree roof pitches that the height of the flue outlet should be at least 1800mm above the roof when not close to the ridge and above 38 degree roof pitches the flue outlet height should be 2300mm horizontally back to the roof flue height figures are given in the table above where the flue is not close to the ridge. Gas flue blocks have been specifically designed for use with gas effect fires.
