Our round catalytic combustors are made from high quality materials right here in the USA! Made to fit specific heating applications, these wood stove combustors are guaranteed to deliver superior performance. Our Environmental Protection Agency approved products have a honeycomb design that effectively traps exhaust gases and helps to reduce air pollution, prolonging the life of your stove!

Depending on your stove's manufacturer, a canned or uncanned combustor will be required for use with your application. We have both! These reliable combustors are designed to withstand thermal shock better than the competition. If you need help figuring out which round catalytic combustor your stove needs, please give us a call at 1-888-986-1535!

What is the difference between canned and uncanned catalytic combustors?

canned ceramic combustor is wrapped with a welded stainless steel strip. This metal accelerates the catalytic reaction of converting smoke to burn as fuel. You will notice an interam gasket tucked in between the metal strip and the combustor itself. 

An uncanned catalytic combustor is simply not wrapped with the metal strip.

Some manufacturers use canned combustors, while others choose uncanned. There is no real reason why - it is a preference. However, it is important that you replace your combustor with the appropriate product. Never install an uncanned combustor on a heat source that originally housed a canned combustor.

What type of heating application uses a catalytic combustor?

Only wood burning applications require a catalytic combustor. We highly recommend checking the owner's manual that came with your fireplace, insert, or stove to verify that your heat source does in fact utilize a combustor. If your application does in fact use one of these devices, remember to never burn coal, lighter fluid, treated or painted wood, paper logs, or trash within the firebox!

How often should I replace my honeycomb combustor?

Catalytic combustors operate for approximately 10,000 to 12,000 hours. However, it is a good idea to check the integrity of your combustor periodically, especially if the performance of your stove changes. Once combustors become heavily contaminated with smoke, gases, or foreign materials from the burn process, you may start to notice signs of cracking or deterioration. When you see this, the combustor should be replaced as soon as possible.

Will I need a gasket for my combustor?

Canned combustors come with a stainless steel band around the outside. Between the combustor and the metal strip is an interam gasket wrap. When you replace your canned combustor, the gasket is included.

Uncanned combustors have no stainless steel banding and must always be installed with a new expanding gasket. We offer a soft, lightweight and flexible protective gasket for this situation. The 1/16 inch thick gaskets come in 2 or 3 inch widths and can be ordered by the foot. When exposed to high temperatures, water particles that have been chemically bound to the material is released. This process cools the outer surface of the combustor and reduces extreme heat transfer, thus protecting your wood burning application from overheating. CLICK HERE to get an interam gasket for your uncanned combustor!
