OlsenBoiler273_1The OMGB Series II/OMGC Series is available in nine sizes from 50 MBH to 299 MBH and is designed for chimney-vent applications. With efficiencies up to 83.9% AFUE, the latest design features a Honeywell Control that monitors water temperature and delays burner start until residual heat has been transferred to the system for maximum efficiency. An integral Draft Hood and Automatic Vent Damper reduces the overall height and footprint of the boiler making it ideal for low clearance/space limited installations.

Boiler Type: Hot Water


• Available in 9 sizes from 50 MBH to 299 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/Electronic Ignition Control
