27130-14 AERCO BOILER BLOWER PROVING SWITCH KIT 

Normal Stock Item

AERCO 27130‑14 is the OEM Blower Proving Switch Kit, confirmed across multiple grounded distributor sources. This kit contains the components required to verify blower airflow before ignition—an essential combustion‑safety function in AERCO boilers and water heaters.

🔧 Core Identity & Function

Part Number: 27130‑14 Component: Blower Proving Switch Kit OEM: AERCO

This kit ensures the boiler does not ignite unless proper airflow is detected. It monitors blower‑generated pressure and sends a signal to the control board once draft conditions are confirmed. If airflow is insufficient, ignition is locked out—preventing unsafe combustion, gas buildup, or burner misfire.

📐 Technical Role

• Confirms blower airflow before ignition

• Prevents burner operation under unsafe draft conditions

• Provides pressure‑sensing hardware and connection components

• Supports safe startup sequencing and stable combustion operation

Applications

Used in:

• AERCO commercial boilers

• AERCO commercial water heaters

Typical service scenarios:

• Ignition lockouts due to airflow faults

• Blower proving failures

• Replacement during combustion‑air system maintenance

AERCO 27130‑14 Blower Proving Switch Kit — OEM safety and airflow‑verification kit for AERCO boilers and water heaters. Confirms blower airflow before ignition, preventing unsafe burner operation and ensuring proper draft conditions. Includes pressure‑sensing components and connection hardware for reliable, code‑compliant combustion safety.
