Description

The FAMCO WDC wind directional chimney cap is designed to be an effective solution to chimney downdraft in windy areas. The cap separates the wind stream as it flows over the cap, while the rotating hood is kept in proper position (relative to the wind) by the wind vane. Air movement past the hood creates a partial vacuum in the flue, enhancing draft efficiency and helping to prevent downdrafts. Quality constructed from heavy-duty 26 gauge galvanized steel. This product does not include a built-in bird screen. We recommend using Bostik High Temp Stainless Anti Seize on the rotating bracket and cleaning creosote buildup to ensure cap functions correctly and is able to rotate without issues, this should be done annually or else as needed. The FAMCO WDC wind directional chimney cap is engineered to slip around the OD (outside diameter) of a single wall pipe. For double/triple wall pipe, we also offer our WCASS wind cap adapter which will fit inside an insulated, double or triple wall pipe to create a mount for your wind directional cap (sold separately). The FAMCO WDC wind directional chimney cap comes in a range of diameters from 5 inch to 14 inch with heights ranging from 14½ inch to 27 inch, see our specs sheet for more details. The FAMCO WDC Wind Directional Chimney Cap is manufactured by FAMCO in the United States and comes with a 1-year warranty against product defects and workmanship.

    This is not a size we are currently able to manufacture, unfortunately.
    2. I have an 8” outside diameter double insulated stovepipe. If your cap slips over the stovepipe I don’t understand why I’d need an adapter?

    If you do not properly shield the outer wall of your pipe from the elements it could lead to corrosion or water damage.
    3. I will need to transition from rectangle masonry to round for wind directional vent. Does the transition insert inside the chimney or outside?

    This transition fits over the outside of the flue and features a drawbolt band to tighten against the outer perimeter.
    4. Heavy winds (20-30mps gusts) are blowing our hot water heater pilot and the main flame when it's heating. I can feel the wind blowing down the pipe when this happens. Do you know if the directional chimney cap will help for hot water heater pipes?

    Yes - this cap is designed to turn with the wind to block gusts from blowing down your pipes, and helps prevent backdraft in most applications where this is an issue.

  1. Terry (store manager) –

    Works like a charm

    Been using the wind directional chimney cap for a few years now, will never use anything else as this does well. Great staff, products, will always come online to get our contractors supplies at Famco. Would definitely recommend

  2. Gary –

    Stovepipe cap

    Just hooked it up but it looks like it’s going to work great

  3. TJ –

    GREAT product!

    i was forced to run my stove pipe up on a steep part of a gambrel roof. when winds would come from the north, I would get MASSIVE downdrafts. After installing this chimney cap, the drafts were GREATLY minimized and i’m able to have wood burning fires on any day, regardless of the wind direction. Truly a great product and great value.

  4. Charles Osborne –

    Our draft increased .02 from .01 and now our furnace is doing wonderful.

  5. Leana (verified owner) –

    Nicely made, well packaged, arrived ahead of schedule. Only problem was 1 wingnut was not threaded.

  7. Aidan Q –

    This wind directional cap is ingenious. It works like a charm. For my application, however, it turned out not to be a great solution….and this is where FAMCO shined! I made an inquiry about an alternative product; Within that day they had reviewed my inquiry, presented a sensible and appropriate solution, and placed a new order under warranty, which was more than they really had to do. The replacement product arrived in three days and it has solved the issue and is performing perfectly! Three cheers for this company and the fact that they gleefully stand behind their products!

  8. Bruce M. (verified owner) –

    wind cap moves nice and freely and service was great. l bought it to use on a wood burning tent stove when camping. Had a first time desert camping with heavy winds blowing the smoke back down the stove pipe. looking forward to tiring it.
