The serial number represents the unique number for that
burner and is a critical number that will be needed for
any communications with Webster Combustion.
The input rates define the maximum and minimum inputs
for that burner, given in MBH for gas and GPH for oil.
Air atomized burners show both the oil pressure and
air pressure. Pressure atomized burners only list the oil
pressure. For gas firing, the gas manifold pressure is
given in "in wc" which is inches of water column.
The electrical ratings of the burner are given, with the volt-
age, current load, frequency and phase (this will either
be single or 3-phase). For motors, the motor HP is listed.
