Welcome to InspectionFire.
In this video, we’ll walk you through how to use the 3-2-10 Calculator to determine if your chimney height meets the minimum code requirements.
Start by opening your Forms tab and navigating to the Calculators and Chase Cover folder.
Then select the 3-2-10 Calculator.
Begin by entering a Job Identifier and the Location of the Appliance.
Next, select the type of chimney, and indicate if any portion of the structure is higher than the termination of the chimney.
You’ll then choose the roof pitch type — either Single Pitch or Multi Pitch.
For a Single Pitch Roof:
Enter the Roof Pitch and the Distance to Peak.
Then input the actual height of the chimney from the highest point of roof penetration.
For a Multi Pitch Roof:
Start by entering the Roof Pitch and Distance to Peak for the first section.
If applicable, add the height of any vertical wall.
Then, enter the additional roof pitch and distance to peak for the second section.
Finally, input the actual chimney height from the highest point of roof penetration.
The calculator will then determine whether the chimney meets the minimum 3-2-10 clearance requirements.
Once all the information is complete, click Next, then Submit to save your results.
Fast, accurate, and code-compliant — made simple with InspectionFire.
