Raypak 008171F Pressure Switch

For veteran technicians and boiler contractors, the Raypak 008171F Pressure Switch is the direct OEM replacement engineered for high-demand diagnostic air proving. This Normally Open (N/O) blower pressure switch is calibrated to a precise 1.10" WC setpoint, ensuring the combustion blower generates sufficient static pressure before the ignition sequence initiates. Constructed with robust industrial-grade materials—including a brass housing, Buna-N diaphragm, and stainless steel internal components—this switch is designed to withstand the corrosive environments common in commercial hydronic and pool heating applications. It features a high electrical rating of 15 amps at 120V AC, allowing for seamless integration with existing control boards and safety strings. Whether you are servicing Raypak Hi Delta units or Protege above-ground heaters, this 008171F switch prevents unsafe operation by monitoring the air pressure differential across the blower assembly to ensure proper venting and flue gas evacuation.

• Precise Calibration: Factory-set at 1.10" Water Column to maintain strict safety standards for air proving.
• Superior Durability: Engineered with brass and stainless steel wetted materials for maximum corrosion resistance.
• OEM Compatibility: Fits a wide range of Raypak models including the H-1529B through H-2339B and Hi Delta series.
• Safe Operation: The Normally Open contact configuration ensures the heater fails safe if the blower motor loses RPM or the vent is obstructed.
• High Electrical Capacity: Rated for up to 15 Amps, providing a reliable interface for modern HVACR control systems.

What are the symptoms of a failing Raypak 008171F pressure switch?
Technicians often see "Water SW Open" or "Air SW Open" error codes. If the blower runs but the burner never ignites, the switch may be failing to close at the 1.10" WC threshold due to a ruptured Buna-N diaphragm or internal scale buildup.

Can I use a higher WC rated switch as a substitute?
No. Using a switch with a different Water Column rating can lead to hazardous combustion conditions or frequent nuisance lockouts. Always match the OEM 1.10" WC specification for this specific blower assembly.

Is this switch suitable for both Natural Gas and Propane Raypak heaters?
Yes, the 008171F blower pressure switch is typically utilized across both fuel types, provided the model requires a 1.10" WC differential for the air proving safety circuit.
