Utica Boilers SW Series II Brochure

85% AFUE Oil Fired Hot Water Boiler

• Side Wall Vent Oil Boiler with or without Tankless Water Heater, 

available in 3 sizes from 91 MBH to 175 MBH.

• Dependable Cast Iron Heat 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 and Circulator Relay Control. 

  

 

- Digital temperature display and diagnostics.

 

- Less Coil: Control monitors water temperature and delays the burner 

starting until any residual heat has been transferred. Thermal purge 

logic measures rate of temperature change inside the boiler and delays 

burner firing accordingly. This maximizes efficiency by turning on the 

burner only when needed.

 

- With Coil: The Boiler utilizes a Honeywell non-thermal purge High Limit, 

Low Limit and Circulator Relay control.

• Direct Exhaust Vent Pipe Kits and Termination Kits (Sold Separately).

• Optional Tankless Heater Coil.

• Textured paint Jacket.

• Limited Lifetime Warranty (Residential Applications).

• Made in the U.S.A.
