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 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.
