Condar Replacement Catalytic Combustors - 7-in. Round X 2-in. - 41730

This replacement 7 inch catalyst fit my Vermont Castings wood stove perfectly. I also purchased a new catalyst thermometer which I easily cut to length just above the catalyst. It is so easy to operate the air intake to stay within the proper operating temperature range. The stove gives off much more heat than when I was using it without a catalyst. But the most important observation is that now there is no visible smoke coming from the chimney. None, never! Also, I have never smelled wood smoke in the air with this catalyst. I have been using it for several weeks and am thoroughly pleased with the product, the warranty, and prompt shipment.
