Chimney Liners

Napoleon Direct-vent fireplaces have enabled far greater flexibility in the placement of home heating units because they don't need access to a masonry chimney or a freestanding flue above the roofline. Prefabricated from metal, they use zero-clearance technology (see zero-clearance fireplace) and have a glass door that securely seals the combustion from interior rooms. Air for combustion is drawn outside. Air for convection is drawn from inside the room, circulated through passageways around the firebox and heat exchanger, and then returned it to the living space without ever coming into contact with the fire itself.

Napoleon Direct-vent fireplaces burn very efficiently, extracting most of the heat from the combustion gases. Unlike wood-burning stoves, they produce virtually no particulates, require no user maintenance or clean-up, and are simple to operate, using a switch, or even a remote control, and a thermostat. On the other hand, although they burn cleanly and efficiently, they do use a non-renewable, fossil-fuel resource and, like all combustion devices, produce carbon dioxide, which contributes to global warming.
