Power Vented Gas-Fired Unit Heaters

Power Vented Gas-Fired Unit Heaters

The perfect way to efficiently heat an ample space such as a large pole barn or a commercial or industrial warehouse. Easy to use and time tested for quality and durability. The PDP model series expands on the size range of the Hot Dawg Series. Our commercial-grade power vent unit heaters come with either a propeller fan or centrifugal blower fan in seven different sizes.

  • 83% thermal efficiency, maximizing seasonal efficiency through the use of a collector box and the power exhauster.
  • A power exhaust can rotate 180° allowing the unit to be vented vertically or horizontally.
  • A 100% shut-off if the unit does not light, to ensure that unburned gases do not build up in the unit.
  • An intermittent pilot-ignition system with continuous retry to keep the unit from locking and needing to be rest if the unit does not light on the first try.
  • All PDP/BDP units to be field-converted from natural gas to propane if desired.
  • A safety pressure switch monitors the vent pipe to assure flue gases leave the building and do not back up in the space.
  • Designed to utilize the smallest diameter vent pipe possible.
  • BDP models are designed to operate against 0.5 inches of external static pressure.
  • “Wing” screws so that the bottom pan can be dropped without a screwdriver or nut driver.
  • A level hanging mechanism for easy field adjustments after adding accessories that may change the unit’s center of gravity.
  • Designed, Engineered & Assembled in the USA
