The filter above the tank is a pot type filter with cloth strainers. The tank is equipped with a drain plug on each end and hand pump to empty water from beneath the oil without emptying the oil storage. The tank is baffled and has two toe steps for easy service. The tank is usable with Heatwave Models 150 and 250. All furnaces require a 20 psi. compressed air source for atomizing the warm used oil.
