BC Series II

Up to 85% AFUE Oil Fired Hot Water Boiler

There Are Some Things You Can Always Depend On...

- Available in 3 sizes from 133 MBH to 161 MBH.

- Dependable Cast Iron Exchanger with Cast Iron Push Nipples.

The Sections and Push Nipples expand at the same rate when

heated. By using similar materials instead of less expensive

gaskets the boiler maintains a water tight seal over time.

- Honeywell High Limit/Electronic Ignition Control.

starting until any residual heat has been transferred. Thermal purge

logic measures rate of temperature change inside the boiler and

low limit calls the control seeks maximum temperature to satisfy

domestic hot water call bypassing thermal purge logic.

- Atmospheric Chimney Vent Boiler.

- Optional Tankless Heater Coil.

- Textured paint Jacket.

- Limited Lifetime Warranty (Residential Applications).

- Made in the U.S.A.

(1) AHRI burner capacity is based on an oil heating value of 140,000 Btu/gal and with 13% CO2.

(2) Net AHRI Water Ratings shown are based on a piping and pickup allowance of 1.15.

(3) Consult manufacturer before selecting boiler for installations having unusual piping and pickup requirements, such as intermittent system operation, extensive

piping.

(4) For forced hot water heating systems where boiler and all piping are within the area to be heated, select boiler on basis of its Heating Capacity.
