Step 1: Determine Total Opening In Square Inches
Determine the type of opening, measure and calculate total "opening in square inches". The total "opening in square inches" refers to the fireplace or appliances over-all face opening.
 |  |  |  |
| One-sided | Two-sided (See-through) | Corner | Three-sided |
| A x B | 1.5 x A x B | A x B | ( A + B ) x C |
| Example: 18" x 24" = 432 sq. in. | Example: 1.5 x 18" x 24" = 648 sq. in. | Example: 18" x 24" = 432 sq. in. | Example: (24" + 24") x 18" = 864 sq. in. |
Step 2: Use Flue Size To Determine Correct Fan Model
