Williams 9929 Kit
The Williams 9929 is a professional-grade oval vent starter kit engineered specifically for Forsaire top-vent furnaces, including models 3508, 5008, 5508, and 6508. As a veteran technician, you know that transitioning from an oval heat shield to a standard round flue requires precision components to maintain draft integrity and structural stability. This OEM Williams furnace part provides a streamlined oval to round adapter solution, ensuring your gas wall heater venting meets code while simplifying the vertical run. The kit is constructed from heavy-gauge galvanized steel to withstand high flue gas temperatures and resist corrosion over time.
This B/W vent kit includes two 2-foot lengths of 4-inch oval pipe, giving you a 4-foot total vertical start right from the top of the furnace. The hold down plate and dual starter plates are essential for securing the assembly and establishing the necessary clearance from combustibles. Whether you are performing a new installation or a system retrofit, using the correct 9929 vent assembly ensures a leak-free connection between the furnace high-limit area and the chimney or vent stack.
Key Benefits for the Contractor- Universal Forsaire Compatibility: Designed to fit the Williams Forsaire series, eliminating the need for field-fabricated transitions.
- Complete Installation Package: Includes the oval to round adapter, hold down plate, and spacers required for a code-compliant startup.
- Durable Construction: High-quality galvanized steel ensures long-term HVAC venting reliability and thermal resistance.
- Optimized Draft Performance: Engineered 4-inch components maintain the proper static pressure for efficient combustion gas exhaust.
Is this kit compatible with Monterey series heaters?
No, the Williams 9929 is specifically configured for Forsaire top-vent models. Always verify your furnace model number before ordering to ensure the base plate and adapter alignment are correct.
Does this kit include the round vent pipe?
This kit provides the oval pipe and the transition to a round profile. You will still need standard 4-inch round B-vent pipe to complete the run to the roof cap.
Why are the starter plates necessary?
The starter plates maintain the required air gap between the oval vent pipe and the wall studs, preventing heat transfer and ensuring the installation stays within fire safety margins.
