Modine Vertical Power Vented Unit Heater (PDP/BDP)

Features:
Each Modine power-exhausted unit heater has been engineered to include the following features:

  • 80% thermal efficiency, maximizing seasonal efficiency through the use of a collector box and the power exhauster.
  • A power exhaust that can be rotated 180°. The unit can be vented vertically or horizontally.
  • A 100% shut-off, intermittent pilot-ignition system with continuous retry, at no extra charge. This ignition system allows for all PDP/BDP units to be field-converted to propane, if desired.
  • A safety pressure-switch to assure safe venting conditions.
  • Designed to utilize the smallest-diameter vent pipe possible.
  • PDP 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.
