Series LC/LCE™

Products » Commercial Boilers » Series LC/LCE™

The LC/LCE™ is available with outputs to 3,777 MBH. This advanced boiler design includes integral cast iron flue collector, unique Flex-Seal gaskets and individual draw rods. Boiler efficiencies are compliant with federal and ASHRAE 90.1 requirements. The top and front cleanouts allow for easy cleaning ensuring highest operating efficiency. The pressurized, forced draft firing requires only a three foot vent above the roof. The LC™ has cast iron rear outlet with integral damper that can be adjusted and locked in position. The LCE™ has cast iron top outlet with butterfly flue damper that can be mounted horizontally or vertically.

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.
