Suspended Hydronic Unit Heater

The Dayton 5PV31 is a suspended horizontal hydronic heater designed for wall or ceiling mounting in commercial or industrial spaces. It uses steam or hot water as the heating medium to deliver warm air horizontally across the room.

Installation Notes

The unit connects via a 1 1/4 inch threaded female NPT fitting and operates on a single-phase 60 Hz supply drawing 0.8 A. Correct piping orientation and secure suspension hardware are essential to prevent leaks or vibration noise.

Hydronic Output Limits

At 2 PSI steam the heater provides 18,000 BtuH output, while 200 F water yields 13,050 BtuH with a 1.3 gpm flow rate. The 9 inch fan moves 395 cfm of air, so the space must accommodate the horizontal airflow pattern and the unit's 15 by 14 5/8 by 9 3/8 inch footprint.

Questions about this item

How do I confirm the heater is operating correctly after installation?

Verify horizontal airflow from the 9 in fan, check that the motor draws 0.8 A at 60 Hz, and ensure the OSHA compliant guard spins freely without obstruction.

What comes in the box and what must I supply separately?

The unit includes the suspended horizontal hydronic heater with red and black plastic housing, 1 1/4 in threaded female NPT connections, and OSHA compliant fan guard; you must supply steam or water piping, electrical wiring for 1 phase power, and mounting hardware.

Which capacity should I choose between the steam and water ratings?

Select based on your heating medium: the heater delivers 18,000 BtuH at 2 PSI steam or 13,050 BtuH at 200 F water with a flow rate of 1.3 gpm.
