Tjernlund Products D-3 Draft Inducer
The Tjernlund D-3 Draft Inducer is a critical inline draft inducer engineered to resolve persistent venting issues in gas and oil-fired furnaces and boilers. Operating at 115V with a motor speed of 1550 RPM, this sidewall vent blower is designed for 3-inch vent pipes and provides consistent negative pressure to overcome restricted flues or poor natural drafts. Built for durability, the D-3 inducer features a heavy-duty motor and high-temperature impeller, ensuring reliable performance in demanding exhaust fan applications. It is essential for maintaining proper combustion air flow and preventing carbon monoxide buildup by ensuring flue gases exit the building safely. Whether you are troubleshooting a venting safety switch trip or replacing a failed draft inducer motor, this unit offers a robust solution for enhancing flue draft in residential and light commercial HVAC systems.
Key Benefits
- Enhanced Combustion Efficiency: Improves 115V motor performance and ensures a steady draft for consistent burner operation.
- Versatile Compatibility: Designed for seamless integration with 3-inch HVAC vent piping in gas and oil heating systems.
- Thermal Protection: Engineered to withstand high flue temperatures, preventing premature motor failure in critical venting paths.
- Simplified Installation: The inline configuration allows for flexible mounting orientations, facilitating quick field replacements for contractors.
Common Questions
How do I know if I need a draft inducer like the Tjernlund D-3?
If your heating appliance experiences pilot outages, soot buildup, or "pumping" of the flame due to insufficient natural draft, an inline draft inducer is necessary to mechanically assist the flue gas exit.
Can the D-3 inducer be used with 4-inch vent pipe?
The D-3 is specifically sized for 3-inch venting. While reducers are available, the static pressure and CFM ratings are optimized for 3-inch applications to maintain code-compliant venting.
Is the D-3 compatible with a pressure switch for safety?
Yes, for HVAC automation and safety, it should be wired through a proving switch to ensure the blower is active before the burner fires.
