Pellet stove inserts have come a long way over the years. They now have the sophisticated look of a gas stove, but don't require the plumbing needed for a gas burner. Instead, they run completely on compressed biomass fuels such as wood pellets, corn, soy beans, cherry pits, and olive pits. For many homeowners, the eco-friendly efficiency of pellet burning fireplace insert is a big plus as well!
Can i remove a direct vet pro pain fire place and replace it with a pellet stove insert? Construction is a wood box not masonry. Front hearth is 18 inches box depth is more than 25 inches.
Unfortunately, you will not be able to replace a direct vent fireplace with any hearth system advertised as an "insert," as the installation of an insert requires an existing masonry or prefabricated wood burning fireplace and you have neither. If you must have a pellet system, I suggest abandoning the existing direct vent fireplace location and purchasing a freestanding pellet stove.
When installing a pellet stove insert, what type of flue liner is required? Is it necessary to run the flue liner all the way the the top of the chimney and cap it? Or can you run the flue liner to just below the chimney cap?
Both wood burning and pellet inserts are very much the same in the fact that they should use a 304 or 316 stainless steel liner system, flexible or rigid, that is sized to the opening of the flue collar on the appliance. The liner can indeed be supported and terminated just below the existing chimney cap. It is not necessary to use a factory top plate and cap, if the existing cap is in good condition. Metal strapping or fabricated brackets can be used to support the liner.
