The Kimberly™ wood stove is approved to use 3-inch double-wall stainless steel pellet stove pipe with a Class-A passthrough.The Katydid™ wood stove is approved to use a 4-inch double-wall stainless steel pellet stove pipe with Class-A passthrough. A Class-A passthrough is typically a cathedral ceiling support box or thimble with double wall insulated or triple wall air-cooled Class-A pipe passing from the ceiling through the attic and roof.
This unique venting system saves owners hundreds of dollars in installation costs, often as much as $1200 – $1500 in savings, simply because pellet stove pipe is far less costly than using Class-A chimney pipe for the entire length of the chimney, as other wood stoves require. This savings helps to balance out the cost of the stoves, making total installation costs similar for a wood stove selling at half the cost.
See our Kimberly™ and Katydid™ Owner’s Manuals for installation instructions appropriate to your application. Never follow installation instructions which may be provided by pipe manufacturers.
