N/A The BPD-75 tank-type commercial gas water heater is intended for light-duty applications such as small office buildings and duplex apartment homes. The BPD-75 features a power direct-vent design, with a factory-installed blower. The blower permits sealed combustion direct-vent operation, with separate venting and air intake runs from outside the structure. The BPD-75 offers installation versatility by allowing venting and intake runs up to 50 feet, using 3" Schedule 40 PVC pipe.

The power direct-vent design also eliminates the potential for performance and safety problems caused by negative air pressure, a problem found in many commercial applications with inadequate indoor ventilation.

Dynaclean™ II Automatic Sediment-Cleaning System
  • Specially designed dip tube directs incoming cold water to create turbulence in the tank to reduce lime and sediment buildup.
  • Prolongs tank life, maintains high energy-efficiency, maximizes hot water output.
Permaglas® Glass-Lined Tank
  • Glass lining and anode rod protect steel tank from corrosion.
Quiet Modular Blower
  • Built-in safety device prevents pilot or main burner operation if blower is not operating.
  • Blower has 110/120 V electrical system, with maximum 2-amp draw.
Durable Brass Drain Valve
