DI-3 DRAFT INDUCER FOR 8-12" PIPE
Field Draft Inducers solve the drafting problems caused by short chimneys, undersized flue pipes and negative building pressures.
Draft Inducers are designed for easy installation in a wide variety of applications, including oil or gas-fired furnaces, water heaters, and boilers. For venting single or multiple appliances, use a control kit.
DI Paks are available for 24 volt and millivolt applications and include all controls necessary.
When to use a Draft Inducer
• Long horizontal vent runs
• Undersized flue pipes
• Short chimneys
• Outside exposed chimney
How Draft Inducers Work
1. Thermostat calls for heat.
2. The Inducer control is activated. This energizes the Draft Inducer (A) which creates negative pressure or draft.
3. The draft closes the negative pressure proving switch and starts the burner (B).
4. When the thermostat is satisfied, both the burner and Draft Inducer shut down
Note: Pressure switch required according to NFPA code.
Not for sidewall venting.
