Quality Construction Features:

A. Water side or steam side interior accessible for cleanout and inspection, front and rear openings, upper and lower drums.

B. Large volume water leg downcomers promote rapid internal circulation, temperature equalization and efficient heat transfer.

C. Boiler tube and furnace area access panels: heavy gauge steel casing with 2" high-temperature ceramic fiber insulation, bolted and tightly sealed to boiler frame.

D. Flame observation port in access door at rear of boiler.

E.Singlesideaccess;combustionchamber,tubesandburner head are completely accessible from one side simplifying maintenance and minimizing floor space.

F.Minimum sized flue vent.

G.Control panel: all controls installed with connections to terminal strip.

H.Forced draft, flame retention head type burner. Efficient combustion of oil or gas, plus quiet operation.

I.Heavy steel boiler frame, built and stamped in accordance with the appropriate ASME Boiler Code.

J.Heavy gauge steel boiler jacket with rust-resistant zinc coating and enamel finish, insulated with 1½" fiberglass to ensure exceptionally cool outer surface.

NOTES:	(1) W = Water / S = Steam
	(2)	Output and horsepower based on boiler industry standard of 80% of input.
	(3)	Output and horsepower based on an average natural gas combustion efficiency of 83.5% for hot water boiler. Actual combustion efficiencies for oil will be higher.
	(4)	Lbs. steam per hour from and at 212°F.
