Draft Inducer for Boilers and Furnaces

The Field Controls DI-3 Draft Inducer is built for oil or gas-fired boilers, furnaces and water heaters. It fits vent pipe diameters from 8 in to 12 in and accepts an 8 in inlet and outlet. The unit is constructed from galvanized steel and is rated for 115 V operation.

Galvanized Steel Construction and Sizing

The galvanized steel housing resists corrosion in high-temperature flue environments. Its dimensions suit a pipe slot height of 5 1/2 in and width of 12 7/8 in. The blower assembly mounts directly to the appliance vent connection without additional adapters.

BTU Input Limits and Vent Range

The inducer supports a maximum gas appliance input of 835,000 BtuH and a maximum oil appliance input of 1,030,000 BtuH. It covers vent pipe diameters between 8 in and 12 in. Appliances exceeding these BTU ratings or requiring larger vent diameters fall outside the operating range.

Questions about this item

Will the 8 in inlet or outlet need periodic cleaning?

The 8 in inlet and outlet diameters can accumulate soot or debris over time, so inspect and brush them during routine appliance servicing to maintain proper draft.

What limits continuous operation on a gas-fired unit?

The maximum heater BTU input for gas appliances is 835,000 BtuH; exceeding this rating will cause the draft inducer to become the limiting factor under sustained use.

How much heat does the 115 V motor add to the mechanical room?

The 115 V motor converts electrical energy into heat during all-day operation, raising ambient temperature in the mechanical room proportionally to its wattage draw.
