In-Line Draft Inducers
Provide positive draft for smokepipe to aid proper exhaust of combustion gases.
Draft inducer is mounted to vertical, horizontal or inclined breeching between a barometric draft control (if installed) and as near a chimney as possible when vent system terminates through roof. Useful when restricted boilers and furnaces, poor chimneys or negative pressures in the building prevent proper exhaust of combustion gases. Aluminized steel housing and wheel, motor heat shield, oversized conduit box. Variable draft control permits adjustments to individual application requirements. 115V, 60 Hz. For Nos. 4C730 and 4C731, CSA listing does not apply unless used with No. 4C725 fan proving switch. Nos. 4C730 and 4C731 have screw attachment only, no fastening bands.
Uses: Great for oil, gas or coal fired systems in commercial and industrial applications. Not for use in sidewall venting or wood burning applications.

Interlock Controls
To satisfy national mechanical codes, draft inducers must be interlocked with burner circuits.

Universal Interlock Control
Simplifies the electrical interlock with any 24/120VAC burner circuit and features adjustable pre/post purge, LED status indicators, and fault code memory.
LED status and fault indicators help simplify new installations and service calls. Electrical junction box can be positioned for easy wiring and service.
