How Draft Inducers Work
1. Thermostat calls for heat.
2. Control Kit (A) energizes Draft Inducer (B).
3. Draft Inducer forces air flow in chimney, creating negative pressure
in burner chamber.
4. Once negative pressure (draft) is established, the Control Kit allows
the burner (C) to start.
5. When the thermostat is satisfied, the Control Kit shuts down the
burner and the Draft Inducer.
Field Draft Inducers solve the drafting problems caused
by short chimneys, undersized vent 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.
When to use a Draft Inducer
• Long horizontal vent runs
• Undersized vent pipes
• Short chimneys
• Outside exposed chimney
Note: CK Control Kit required according to NFPA code.
Not for sidewall venting.
