Durable, Efficient Construction
Corrosion-resistant, cast-iron boiler sections mean that your LGB will withstand the rigors of even the most trying applications. The sections also contain heat pin studs which improve heat transfer and efficiency by diverting hot gases.

Efficiency-Boosting Insulation
Heat retention is critical to energy efficiency. Heat leakage represents energy use without any comfort gains. An extended, insulated steel jacket prevents heat from escaping the LGB and improves the efficiency.

Captured Seals
Elastomer rings seal the sections’ ports better than traditional metal push nipples. The elastomer expands and contracts with the section, maintaining a watertight seal in all conditions.

Easy Maintenance
Keeping the LGB clean and running efficiently is a breeze. The rear jacket and steel cleanout plates are easily removable, providing quick access to the flue passages.

Jumbo Top Port
The top port opening of the LGB Gas Boiler Weil-McLain is 9 and forms an internal header within the unit. This improves water circulation

Jumbo Steaming Area
Weil-McLain believes you should never have to wait for dry steam. The LGB Gas Boiler features an extra-large steaming area for express steam generation and ideal comfort.
