This fire-tube boiler is brand new and weighs around 425 lbs. It measures 72" high to the top of the stack x 25" square at the base. The boiler itself is 16" dia. x 38" tall. Two pop-off valves are set at 100 lbs. The injector is a 3/8" Penberthy. The boiler has 36 copper tubes. The copper tubes are 7/8". The firebox is nearly 16" in dia. x 12" tall with plenty of room for large pieces of wood or lots of coal. Ash pan and grates are built into the firebox and base. New features on this boiler are the blower ring and petticoat stack which can be seen in the last two photos. With the addition of these two items the draft is increased by ten times. The amount of air moving through the fire is amazing.
