Suburban NT Series Furnace Discharge Vent | 260573 | 6 Inch

Replace the discharge outflow vent on your Suburban NT Series RV furnace with the Suburban 260573 Discharge Outflow Vent. This genuine Suburban OEM 6-inch vent is the exhaust component that routes combustion byproducts from your furnace to the exterior of your RV — a critical safety component for proper furnace operation. The right replacement when your existing discharge vent has failed, become damaged, corroded, or compromised.

For Suburban NT-16S and NT-20S Series Furnaces

The 260573 is designed for the Suburban NT Series furnace lineup:

• Suburban NT-16S Series — including SE, SEQ, and SQT line variants
• Suburban NT-20S Series — including SE, SEQ, and SQT line variants

Verify your existing furnace model on the manufacturer label before ordering — the 260573 is designed for the NT-16/NT-20 series and is not interchangeable with other Suburban furnace platforms (such as the SF Series).

What This Vent Does

The discharge outflow vent is the exhaust pathway component on your Suburban NT Series furnace:

• Routes combustion exhaust gases from the furnace burner to the exterior of your RV
• Maintains proper exhaust flow for efficient combustion
• Critical safety component — prevents exhaust gases from entering the RV living space
• Weather-resistant exterior interface at the RV sidewall

A failed or damaged discharge vent can compromise both furnace operation AND occupant safety — exhaust gases from propane combustion include carbon monoxide, which must be reliably routed to the exterior.

Common Failure Symptoms

Common reasons to replace the discharge outflow vent:

• Visible damage — cracks, dents, corrosion, or physical impact damage
• Loose or compromised mounting at the RV sidewall
• Visible rust or deterioration from years of weather exposure
• Weather sealing has failed — water intrusion around the vent
• Vent has been damaged in transit — road debris impact, low-clearance contact
• Furnace exhaust appears blocked or restricted by debris or damage
• Preventive replacement during broader furnace service

6-Inch Length

The 260573 features a 6-inch length, the standard size for NT-16/NT-20 Series furnace exhaust routing. Verify your existing vent length matches before ordering — vent length needs to match your RV's wall thickness and furnace mounting depth.

⚠️ Professional Installation Required

RV furnace exhaust vent replacement involves working with the RV exterior wall, weather sealing, and propane appliance exhaust system. Improper installation can result in:

• Carbon monoxide exposure if exhaust isn't properly routed to the exterior
• Water leaks from compromised exterior wall sealing
• Furnace operation problems from restricted exhaust flow
• Fire risk from improperly sealed or routed combustion exhaust

Installation should be performed by a qualified RV service technician with experience working on Suburban furnaces. Always verify proper exhaust flow, weather sealing, and safe furnace operation after replacement.
