What's the size diameter of your stove outlet?
What is your chimney height to roof?
To measure your chimney height to roof, measure the distance from the bottom of the support box on the first ceiling (or 2 inches below the first ceiling) to where the chimney penetrates out of your roof.
We will calculate the sections of chimney pipe needed for your installation.

Many confuse the terms. Stove pipe is usually painted black and is used in the interior on the home until you transition through a wall or ceiling then class A chimney pipe is used thereon. Stove pipe, black pipe, single wall pipe all refer to the same thing. Chimney pipe, class A pipe, triple-wall pipe, insulated pipe all refer to class A chimney pipe. Double-wall pipe could be associated with either double-wall black stove pipe like DVL or double-wall chimney pipe like DuraTech.
For the best draft, use the size diameter pipe matching your wood stove flue collar through the entire installation. If the stove has a 6" flue collar, then you should use 6" stove pipe and 6" chimney pipe through the roof. If your stove has a 8" flue collar then you run 8" stove pipe all the way up.
Measure the exit wall thickness
Measure the thickness of the wall where the pipe will be exiting through.
We will add a chimney pipe section long enough to pass through the Wall Thimble and your wall.
Do you require wall straps to be adjustable?
Fixed wall straps usually allow 2" clearance whereas adjustable wall straps can offer a few extra inches for small obstructions such as gutters.
The minimum clearance for chimney pipe from an outside wall is 2 inches. So, if you can obtain that 2 inches of clearance straight up the outside wall then a fixed strap can be used.
However, if you prefer to have extra clearance from the wall or if you have obstructions in the way like a roof overhang or gutters you want to be 2 inches away from the obstructions, so having the adjustable wall straps makes that clearance easier to obtain. Using adjustable straps allow for 2 to 6 inches of clearance.
How many additional floors will your chimney pass through?
We will add a Firestop Radiation Shield for each additional floor.
Firestop Radiation shields are use when transitioning through additional floors/ceilings to protect the joists from excessive heat. Not required when passing through the roof and fits on the underside of ceiling and adjusts to cover framing. Made of galvalume.
Measure the pitch of your Cathedral Ceiling
Measure the pitch of your cathedral or vaulted ceiling in the same room where your stove will be installed.
Based on your ceiling pitch, we will include the proper length support box required to keep the chimney clear of combustibles.
The ceiling pitch, or slope is expressed as the distance a ceiling rises vertically over a 12-inch horizontal distance. If a ceiling rises 6 inches vertically for every 12 inches horizontally it is a 6/12 pitch
Does your chimney installation require a horizontal offset?
Offsets allow a chimney to navigate around obstructions such as structural supports and electrical wires.
Measure the horizontal distance required to clear the obstruction and the amount of rise available for an offset. Remember standard clearances from walls/obstructions apply.
Based on your measurements, we'll offer the smallest offset available to maximize your chimney draft.
Roof Flashing is the cone-shaped sleeve used to weather proof the penetration of chimney pipe through the roof.
Measure the pitch of your roof and the horizontal distance between your chimney and roof's peak.
Based on your roof pitch and chimney's distance from peak, we will include chimney pipe sections needed above the roof line and adjust the type of flashing for your roof pitch.
The pitch, or slope, of a roof is expressed as the distance a roof rises vertically over a 12-inch horizontal distance. If a roof rises 6 inches vertically for every 12 inches horizontally it would have a 6/12 pitch. Click on link to help you determine what roof pitch you have.
To measure your roof pitch:
1. Set your ladder on the side of your house so that you can safely access the down slope edge of the roof. You will not need to get on the roof for this step, just make sure that you can touch the edge of the roof from the ladder. As you face the house, the roof should slope up from the left to right, not away from you.
2. Hold a framing square up against the roofline so that the long end of the "L" points toward the center of the roof and the short end points toward the ground. Essentially, you are forming a right triangle with the long and short sides of the framing square - the roof edge forms the third side.
3. Position the framing square so that the long end meets the edge of the roof at the 12" mark.
4. Level the square horizontally.
5. Read the measurement on the short end that is standing up vertically from the roof.
6. :::Remember:::Rise over run. The rise is the measure on the vertical leg; the run is the 12" measurement on the horizontal leg. So if the vertical measurement is 6, the roof has a 6/12 pitch.
Roof pitch relates to the slope and inclination angle of a roof in building construction. The primary purpose of a pitched roof is to redirect rainwater. In general, the pitch of the roof is proportional to the amount of precipitation. Houses in areas of low rainfall frequently have roofs of low pitch while those in areas of high rainfall and snow have steep roofs.
Now knowing your roof pitch you can choose the proper roof flashing for your chimney installation. Flashings generally cover a range of pitches. Example; a 0/12 to 6/12 covers a flat roof to a 6/12 pitch roof.
The chimney must extend at least 3 feet above the highest point where it passes through the roof, and be at least 2 feet higher than any part of the building or surrounding obstructions including trees within a horizontal distance of 10 feet. Occasionally, a chimney install requires additional height to reach 2 feet above nearby combustible obstructions taller than the roof peak. Our Chimney Wizard does not account for obstructions other than your roof peak; in this case, we recommend Submitting a Sketch to help ensure you receive the correct pieces for your installation.
If you have a roof with a flat wall such as a gable roof and the chimney exits through and up this wall to your roof peak, set your "distance to peak" to 0. We will calculate the additional chimney sections required for your chimney to meet the 3 feet requirement.
Does your chimney penetrate a roof overhang?
We will add a roof flashing and storm collar to install where the chimney passes through the overhang. Frame for at least a 2" clearance.
We've calculated your total chimney height to be inches. This includes the length above the roof line which is inches.
An extended roof bracket may not be required for this installation. Would you like to add one anyway?
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 or surrounding obstructions including trees within a horizontal distance of 10 feet
Does your chimney cap require a spark arrestor?
A spark arrestor traps particles exiting the chimney. Check your local building codes to determine whether one is required.
Do you require a snow splitter?
We recommend a snow splitter if you live in a snowy area and have a roof pitch steeper than 4/12 or heavy snows.
