The Reznor’s VENTURION® Model RV-225 & RV-325Combination Space Heater/Ductable Furnaces
Reznor® NEW Model RV Venturion® Series Used-Oil-Fired Unit Heaters are available in two sizes with BTUH inputs of 200,000 or 280,000. These used-oil-fired heaters are designed to burn used oil but will also burn No. 2 fuel oils without adjustment. The used oil must be no heavier than 50 weight and not lighter than No. 2 fuel oil.

The heater is shipped from the factory as illustrated, with the warm air discharge on the front. To adapt the heater to the building, the discharge opening may be moved to the rear or divided between front and rear.

The air atomizing burner provides excellent flame retention. Air for atomization of the oil is provided by an onboard piston-type compressor. An oil preheating system (U.S. Patent No. 5,080,579)
heats the oil, maintaining it at a temperature required for atomization but preventing nozzle after-drip. The burner has electric spark ignition and an electronic cad-cell flame safety system
with manual reset. The blower control prevents cold air discharge at start-up and provides continued warm air while the unit is hot after burner shutdown. The safety limit control protects the heater from high temperatures caused by an airflow restriction or motor failure.

Model RV225 is equipped with a direct drive blower and motor and is capable of handling up to .25″ w.c. of external static pressure. Model RV325 is equipped with an adjustable belt drive motor and blower and will handle up to .5″ w.c. of external static pressure. All Model RV units may be connected to ductwork. Both units have a blower inlet guard; Model RV325 has a belt guard. The remote fuel pump mounted on or near the oil supply tank is part of a positive pressure supply system providing a precisely-metered flow of oil to the heater. This positive displacement pump
produces a stable flame under a wide range of operating parameters and allows up to 60 ft of supply line with a 15 ft lift. A fuel line filter with a disposable strainer, a vacuum gauge, and a foot
valve are provided for installation in the line that runs from the supply tank to the fuel pump.

Reznor® Venturion® used-oil-fired unit heaters are engineered to facilitate maintenance procedures required when burning used oil. Model RV units feature a heavy gauge, single passage combustion chamber/heat exchanger with full diameter access at both ends. There is a large, easily removable service panel at the exhaust end and a hinged service panel at the burner end.
To “swing out” the burner service panel, you need only disconnect a single cable connection and remove two bolts.

CAUTION: These heaters are designed to provide economical disposal of used oils. Due to the nature of the fuel being burned, this unit should not be depended on as the only source of heat. Any water or foreign material in the oil may cause the unit to shutdown. A secondary source of heat should always be provided to the building. This will prevent any building damage if the used-oil-fired heater is to become inoperative during subfreezing weather.
