Commercial Boilers - Gas Boilers Series LC/LCE™ Boiler

The forced-draft, cast iron Series LC/LCE™ boiler can be equipped with efficient burners for applications requiring gas, oil or combination gas/oil firing. There are 22 commercial sizes available for hot water or steam applications with inputs of 686 MBH up to 4,663 MBH, and thermal efficiencies of up to 83.7%. The advanced design allows for simpler installation using flex-seal gaskets and individual draw rods, as well as easy access to the boiler via top and front plates for inspection and cleaning. Optional tankless coils can be added for production of domestic hot water.

The manufacturer should be consulted before selecting a boiler for installations having unusual piping and pickup requirements, such as intermittent system operation,
extensive piping, etc. For forced hot water heating systems where the boiler and all the piping are within the area to be heated, the boiler may be selected on the
basis of its Gross Output.
