OIL FIRED BOILERS

The LE series boiler is a low mass, design engineered to allow quick, low energy start-up and up to 86.7% A.F.U.E. operating efficiency. The design incorporates a Beckett® AFG series flame retention burner, cast iron reversing chamber and spiral turbulators to assure best combustion and heat extraction qualities. The burner is mounted on a reversible cast iron swing door for ease of service and maintenance and a dip tube is factory installed for easy air elimination from the water system. Warranties consist of lifetime limited on the heat exchang- er and 1 year limited on entire boiler. The LE boiler is stocked with conventional controls, Burnham’s exclusive EC5000 microprocessor control, a complete comfort system monitor which provides zone control of up to 4 zones, adjusts boiler temperature according to outside temperature to maintain lowest possible water temperature required for desired comfort level, shuts down boiler before room temperature is satisfied allowing boiler to purge remaining heat and avoid temperature over-run, controls domestic hot water production, and provides programmable night setback functions. EC5000 is available as an accessory. The microproces- sor unit receives input from remote room temperature units (RTU) instead of conventional thermostats and an outdoor temperature sensor. The outdoor sensor and 2 RTU’s are included with the EC5000. Additional RTU’s can be ordered separately. This is an excellent alternative to other “Low Mass” systems. When combined with an Alliance™ high efficiency indirect water heater, provides the utmost in high efficiency space heating with domestic water heat- ing. Other standard features of the LE boiler include ASME relief valve, Honeywell R8184G cad cell relay, high limit control, Taco 007 circulator, and deluxe insulated jacket. Equiguard® Extended Service Agreements are available for Burnham Boilers.

OIL FIRED DIRECT VENT BOILERS

The LE direct vent model has the same features as the LE Series. However, in lieu of the AFG burner the LEDV features a Beckett® AFII burner with pre and post purge cycles. Similar to what occurs in a chimney through natural draft, this burner establishes a draft flow in the piping so that all byproducts of combustion are safely vented out of the home. Warranties consist of lifetime lim- ited on the heat exchanger and 1 year limited on entire boiler. Other features include vent terminal, vent connectors, oil nozzle line heater, intake vacuum breaker, intake terminal and vent pipe sealant. Ordered separately is Z-Flex® double wall vent pipe. Equiguard® Extended Service Agreements are available for Burnham Boilers.
