Field Controls 46205414 Vent Kit

The Field Controls 46205414 vent kit (Model SWG-4G) is a specialized side-wall venting solution engineered for 80+ gas draft induced furnaces. This comprehensive kit integrates a 4" SWG Power Venter with a 4" MG-1 Draft Control and a CK-43F control kit to provide active mechanical draft. Designed for installations where a conventional chimney is unavailable or compromised, this system ensures proper combustion by venting flue gases directly through an exterior wall. The inclusion of the fan proving switch within the control kit prevents the burner from firing unless the venter attains the necessary negative pressure. This setup optimizes gas furnace side-wall venting efficiency while maintaining strict safety standards. By utilizing high-temperature stainless steel in the venter construction, the kit manages flue gas evacuation reliably, preventing back-drafting and ensuring consistent performance in tight mechanical rooms or specialized HVAC power venting applications.

Key Benefits

• Enhanced Draft Control: The MG-1 draft regulator stabilizes flue pressure to ensure peak burner efficiency.
• Safe Operation: CK-43F control kit interlocks the furnace with the power venter, ensuring gas flow only occurs during active draft.
• Design Flexibility: Eliminates the need for vertical chimney liners, allowing for horizontal termination in induced draft systems.
• Durable Construction: The SWG venter features a corrosion-resistant housing capable of withstanding acidic flue gas environments.
• Integrated Solution: Combines venting, regulation, and control logic into a single 46205414 vent kit for streamlined installation.

Common Questions

Can I use this kit with a standard atmospheric natural draft furnace?
No, this specific kit is engineered for 80% AFUE gas draft induced furnaces. For atmospheric or oil-fired applications, a different model with specific control interlocks is required to ensure safe combustion cycles.

What is the maximum equivalent vent pipe length for this power venter?
The SWG-4G series typically supports specific run lengths based on the BTU input of the appliance. Always calculate equivalent length, including elbows and terminals, to ensure the blower can handle the static pressure of the run.

How do I adjust the draft pressure for this system?
Draft is adjusted via the MG-1 barometric control and the fan proving switch. A manometer should be used to verify that the negative pressure at the flue outlet matches the furnace manufacturer’s specifications.
