Product Summary

The FAMCO SQ square flue vacuum cap has been used for decades with gas, oil, coal, and wood burning chimneys. This chimney cap increases updraft and prevents downdrafts caused from wind. This works by forcing the wind to alter its direction over one of four gores on the cap. The change of direction creates an area of lower density air (partial vacuum) at the outlet of the pipe. Lower density air creates draft within the exhaust pipe, helping to remove exhaust gases and increasing overall efficiency. The positioning of the cap relative to the prevailing winds is not critical but is slightly more effective when placed with its flat side facing the winds. Quality constructed from 28 gauge galvanized steel. The FAMCO SQ square flue vacuum cap has a rounded corner square base and draw bolt for secure installation. Comes in a range of custom sizes from 8×8 inches, up to 12×16 inches (Length x Width). Measure carefully to ensure a proper fit: this is a custom sized item requiring your exact length and width measurements for the outside dimension of your flue.

  4. We have a square chimney outer edge is 12 1/2 by 12 1/2 inner edge is 10 1/2 by 10 1/2. Would this work for our chimney the sizes look more rectangular. Is there a different option we should look into maybe one with screens?

    Unfortunately, the FAMCO Square Flue Vacuum Caps do not come in that size. We offer the HY-C Draft King Chimney Cap that has a stainless steel construction and screen. This would fit your chimney if you purchase the 13″ x 13″ size.

    Unfortunately, the Square Flue Vacuum Cap – Galvanized does not come with a screen. Please choose the 13″ x 18″ size from the drop down menu to view the price.

  8. I measured my flue at the top of my chimney, and the external dimensions are 8 7/8″ x 16 7/8″. I see that the largest size you have available on your website is just up to 16″. Now my flue is more oval rather than rectangular with curved corners. So I’m wondering if a 8 7/8″ x 16 would actually conform to my chimney. Or do you have an 8 7/8″ x 16 7/8″ option?? Please advise. Thank you.

    These caps are designed for rectangular flues, therefore it would not be compatible with your chimney. It would be best if you use a cap with the shape of your flue.
