*Substitute “P” for completely assembled packaged boiler without burner (WGO-2 through WGO-6 only). Substitute “A” for boiler only for use with approved burners as listed with I-B=R.

** Available only as an “A” unit.

(1)WGO boiler designed with convertible vertical and horizontal flue outlet.

(2)MBH refers to thousands of Btu per hour.

(3)Based on 140,000 Btu/gal.

(4)Based on standard test procedures prescribed by the United States Department of Energy at combustion condition of 13.5% CO2 and -0.02" W.C. draft overfire.

(5)Net I=B=R ratings are based on net installed radiation of sufficient quantity for the requirements of the building and nothing need be added for normal piping and pick-up. Water ratings are based on a piping and pick-up allowance of 1.15. An additional allowance should be made for unusual piping and pick-up loads. Consult local Weil-McLain Sales Office.

(6)I=B=R gross output

(7)See page 12 for minimum breeching diameter.

(8)Listed draft losses are for factory-shipped settings.
