Field Draft Inducers solve the drafting problems caused by short
chimneys, undersized vent pipes and negative building pressures.
Draft Inducers are made with 18 gauge aluminized steel, 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.
NOTE: CK CONTROL KIT REQUIRED ACCORDING TO NFPA CODE.
NOT FOR SIDEWALL VENTING.
Sources of Draft Problems
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.
