The CL Series boiler is a cast iron oil-fired low
pressure steam boiler designed for use in closed
heating steam systems. This boiler must be vented
by natural draft into a fireclay tile-lined masonry
chimney or chimney constructed from type L vent or
a factory built chimney that complies with the type HT
requirements of UL103. An adequate supply of air for
combustion, ventilation and dilution of flue gases must
be available in the boiler room.
The CL Series steam boiler uses a L404F
Pressure Limit and Low Water Cut-off. This boiler
has indirect domestic water heater connections
to generate domestic hot water. Optionally, this
boiler may include a L4006 Temperature Limit and
a tankless heater to generate domestic hot water.
