Clean lines, gentle curves and modern technology meet with the A5780B. This slim line pellet stove is designed to fit into tighter spaces yet produces the same amount of heat as a full size pellet stove. The all-digital control system comes with a temperature readout and a remote control for simple adjustments. It comes with a 40 lb hopper to provide over 20 hours of burn time between fillings. Pellet heaters work by using a software driven control board to precisely deliver a pre-determined amount of fuel from the hopper into a burn chamber. An electric heating element, used only in startup, heats the pellets until they ignite. The combustion blower forces air through the burn chamber and once ignited, it provides an active combustion of the pellets resulting in very little ash. The exhaust and heat pass through one side of air chambers where on the other side, the variable speed room blower gathers the heat and distributes this through the room. This entire process results in a very clean burning, efficient heating machine for your home.
