The VF 3000 Stoker Boiler features our patented Verti-Flow™ Coal Feeder. The VF 3000 has a 5,000 to 95,000 BTU range
and 250 lb. coal hopper capacity.
An aquastat is used to activate the feeder when more heat is needed to maintain the set water temperature. When the
Aquastat senses the water is at the set temperature the feeder stops feeding coal. Now the Verti-flow™ Stoker Control takes
over to maintain a very low fire until more heat is needed.
Properly installed and maintained, your VF 3000 will heat your home for a lifetime. Therefore, have your unit professionally
installed. Consult with your Harman® Dealer regarding proper maintenence.
