Description:
The Modine PDP gas-fired unit heaters feature a blower-powered vent exhaust. This vent forces heater exhaust fumes outside of the heated structure, and allows the heater to be vented vertically or horizontally.
Horizontal venting prevents heat from escaping out of the vent pipe when the heater is not running, which is especially important in greenhouses.
