Rooftop Inducer for Heating Systems

The Tjernlund Products RT750 is a draft inducer built for furnaces and solid-fuel fireplaces. It handles natural gas, oil and solid fuel applications in residential or light-commercial installations. The unit operates on 120V AC and draws 1.2 A. Its wheel is made from stainless steel for corrosion resistance. The housing uses coated galvanized steel for outdoor durability.

Vent Pipe Diameter Limits

This inducer accepts vent pipe diameters from 8 in to 10 in. Both the inlet and outlet measure 8 in. Gas appliances are rated up to 1,200,000 BtuH input. Oil appliances are rated up to 1,500,000 BtuH input. Installations requiring larger vent diameters or higher BTU capacities fall outside the rated range. The 16 in dimension refers to the overall unit size.

Roof Mounting and Wiring

Roof mounting requires proper flashing and sealing to prevent water entry. Electrical connection must follow local codes for 120V AC supply. The stainless wheel resists buildup but still needs periodic inspection. Common issues include incorrect vent sizing, inadequate roof sealing and wiring not rated for outdoor exposure. Professional installation is recommended for safety and draft performance.

Questions about this item

Which rooftop inducer model should I choose for a 16-inch opening?

The RT750 is built for a 16-inch roof opening and fits vent pipes from 8 to 10 inches in diameter.

What does the 1.2 A current draw mean once the unit is installed?

At 120 V AC the inducer pulls 1.2 A, so a standard 15 A circuit provides ample margin for continuous operation.

How does the 8-inch inlet and outlet limit the venting system?

Both connections are 8 inches, so the ductwork and any adapters must match that size to maintain rated airflow.
