Shaded areas are as shipped. Alternate inputs require a field---installed alternate oil nozzle supplied with base model.
* MBH = 1,000 BTU per hour/BTU=British Thermal Unit
** Heating Capacity is based on a 13 percent CO2 with a ---0.02 in. wc draft over fire and a #1 smoke or less. Testing was done in accordance with the D.O.E.
(Department
of Energy) test procedure.
+ GPH = Gallons per hour of oil at 140,000 BTU per gallon
++ A.F.U.E. = Annual Fuel Utilization Efficiency based upon D.O.E. test procedure
# As an Energy Star Partner, the manufacturer has determined that this product meets Energy Star guidelines for Energy Efficiency
}
The 168,000 Btuh input is only available with a Beckett burner.
