Williams P151700 Manifold Gasket 320819-301 The mechanical spring return mechanism

The mechanical spring return mechanism ensures consistent fail-safe positioning during power loss

It monitors different pressure thresholds for low-fire and high-fire stages

specifically if the check is leaking or failing to maintain the required pressure differential (usually at least 5

Technicians should look for hairline fractures in the plastic

Precision Speed Control: 3-speed 1075 RPM design provides flexibility to optimize CFM for heating and cooling cycles

Williams P151700 Manifold Gasket 320819-301 The mechanical spring return mechanismThe Williams P151700 Manifold Gasket is a critical OEM component designed for high integrity sealing in Forsaire Direct Vent Wall Furnaces. Engineered to withstand the thermal cycling associated with the 4007, 5507, and 6007 series, this high grade synthetic gasket ensures a gas tight interface between the manifold and the combustion chamber. For field technicians, maintaining the original equipment sealing surface is vital for preventing combustion
