How do you measure chimney pipe diameter?
- Measure the inside diameter of the flange on your wood stove.
- Determine the distance from the wood stove to the chimney.
- Add 18 inches to the measurement.
- Attach the stovepipe to the flange on the wood stove using 1/4-20-1/2-inch metal or machine screws to secure the stovepipe in place.
Consequently, how do you measure a chimney?
1 – Measure Your Chimney Flue
- Measure inside the chimney SIDE TO SIDE & FRONT TO BACK at the narrowest part of the flue (usually about 600mm above the opening).
- FINALLY measure to the narrowest part of the flue from the top of the fireplace opening.
Likewise, how do you measure flue size? Step 1: Find the cross-sectional area of the fireplace opening. Multiply the W=36" X H=30" and that equals 1080 square inches of fireplace opening. Step 2: If you are using a round liner and the chimney height is more than 8' above the fireplace opening you can divide the 1080 by 12.
Likewise, what is the standard size of a chimney?
Prefab or Metal Chimneys
|Chimney Size||Common Venting Uses|
|Inside diameter (inches)||Inside Area (square inches)|
|8||50.3||Stoves, Small Fireplaces, Central Heaters|
|10||78.6||Stoves, Fireplaces, Central Heaters|
|12||113||Fireplaces, Central Heaters|
How big should my flue be?
As a general rule, the diameter of the chimney should match the flue collar on your wood stove. A 6-inch stove requires a 6-inch flue. In most cases, a step up is also fine. For example, you could vent a 6-inch stove into an insulated chimney that is 8 inches in diameter.
