Vent type:

A-Atmospheric, PV-Power Vent, DV-Direct Vent, PDV-Power Direct Vent, FD-Flue Damper

Gas type:

Every model that ends with BN is natural gas model. Change BN to SX for propane type. (Example: M-I-30T6FBN is natural gas, M-I-30T6FSX is propane water heater). On some models change X to N (example: M-I-MS30T6LX to M-I-MS30T6LN) to order natural gas heater. Models that end with FRN, such as UDS1-40S6FRN, are for natural gas only.

If the table cell has two values... upper values are for natural gas while lower values are for propane.

Models with the energy factor, EF, of 0.67 and over are Energy Star.

Most of the Bradford White gas water heaters with the 50-gallon tank size utilize the Hydrojet system or Hydrojet 2 Total Performance System to reduce or prevent the sediment build-up in the heater's tank. This is done with the specially designed dip tube to generate the turbulent water flow inside the tank.

The ICON system is another advanced feature that combines temperature control, diagnostic codes, system functions, controller, and the LCD display for better control, performance, and efficiency.
