Honeywell swg-3 Sidewall Power Venter 70K Btu 3 Inch

Product Description

The HONEYWELL swg-3 is a sidewall power venter designed to mechanically exhaust flue gases from gas-fired heating appliances through an exterior wall. It handles a maximum venting capacity of 70,000 BTU/h and features a 3-inch inlet and 3-inch outlet, making it suited for small to mid-sized residential heating equipment. Licensed HVAC technicians install this unit when conventional natural-draft venting is impractical or when an appliance requires induced-draft sidewall termination. The power venter draws combustion byproducts out of the appliance and expels them horizontally through the sidewall rather than vertically through a flue or chimney.

The swg-3 is used in residential and light commercial applications where gas furnaces, boilers, or water heaters require sidewall exhaust venting. It is a common solution for retrofit installations where existing chimneys are unavailable, oversized, or lined for a different fuel type, and where sidewall termination meets local code requirements. The 3-inch connection size suits lower-input appliances up to 70,000 BTU/h. Installation typically follows IFGC and manufacturer guidelines for horizontal vent termination clearances.

Key Features

• Maximum venting capacity of 70,000 BTU/h for compatibility with smaller residential gas appliances
• 3-inch inlet and 3-inch outlet for straightforward connection to standard vent pipe
• Sidewall power venting eliminates the need for a conventional vertical chimney or B-vent
• Mechanically induced draft ensures reliable flue gas removal independent of natural convection
• Supports retrofit and new-installation scenarios where sidewall termination is required by design or code

Compatibility

Designed as an OEM-style replacement or new-installation sidewall power venter for residential gas-fired appliances requiring induced-draft sidewall exhaust with a 3-inch vent connection up to 70,000 BTU/h input.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional. Shut off gas supply and disconnect electrical power to the appliance before servicing or connecting the power venter. Sidewall termination location, clearances from openings, and vent pipe routing must comply with the IFGC, local mechanical codes, and the appliance manufacturer's venting instructions. Do not operate the appliance with the power venter disconnected or with the vent path obstructed.
