The FAMCO VCG round base vacuum chimney 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 the flat side facing the winds. Quality constructed in heavy-duty galvanized steel, 3 inch – 5 inch are made with 28 gauge, 6 inch – 9 inch are 26 gauge, and 10 inch – 16 inch are 24 gauge.
The FAMCO VCG chimney cap has a round base and draw bolt for secure installation. The adjustable collar will only provide approximately ⅛ inch of play for tightening to the appropriate pipe size, and is not designed to expand to accommodate different pipe sizes or double/triple wall pipe sizes (NOT designed to fit X&⅛”, X&¼”, X&½”, etc.).Comes for pipe sizes ranging from 3 inch to 12 inch OD and heights ranging from 4¾ inch to 15 inch, see our specs sheet for more details. The FAMCO VCG chimney cap is manufactured by FAMCO in the United States and comes with a 1-year warranty against product defects and workmanship.

For a multi-wall pipe (either double or triple walled), as long as you are using a chimney cap adapter (SKU# WCASS), any of our round based chimney caps can fit the corresponding adapter size. You'll need to select the adapter size that would work with the inside diameter of your innermost pipe size. The skirting on the adapter would then cover the other pipe walls, and then you can select a chimney cap size that matches the adapter size.
