Weil McLain 382-200-317 Pressure Switch Kit 5,500–10,000 ft. Elevation 1.25″ W.C.

Description

The Weil McLain 382-200-317 is a genuine OEM Pressure Switch Kit engineered specifically for high-altitude boiler installations operating between 5,500 and 10,000 feet above sea level. Designed as a direct replacement component for compatible Weil McLain boiler systems, this kit ensures proper combustion safety monitoring at reduced atmospheric pressures where standard pressure switches may not perform reliably.

Why Altitude-Specific Pressure Switches Matter

At elevations above 5,500 feet, atmospheric pressure drops significantly, affecting combustion air density and draft performance. A standard pressure switch calibrated for sea-level operation can fail to open or close at the correct differential, leading to nuisance lockouts or, worse, unsafe operation. The 382-200-317 is factory-calibrated at 1.25″ W.C. to match the precise differential pressure characteristics of Weil McLain equipment operating in high-altitude environments, providing reliable protection without unnecessary service calls.

Key Features

• Genuine Weil McLain OEM replacement pressure switch kit
• Calibrated for high-altitude operation: 5,500 ft. to 10,000 ft. elevation
• Set point: 1.25″ W.C. (inches of water column)
• Monitors inducer/draft pressure to confirm safe combustion conditions
• Direct drop-in replacement for compatible Weil McLain boiler models
• Helps prevent unsafe boiler operation due to insufficient draft or blocked venting

Application

This pressure switch kit is intended for use with Weil McLain boilers installed at high-altitude job sites such as mountain residences, lodges, commercial facilities, and utility buildings located between 5,500 and 10,000 feet elevation. Always verify compatibility with your specific Weil McLain boiler model number before installation.

Installation Notes

• Replace only with the correct altitude-rated switch for the installation elevation
• Verify pressure tubing connections are secure and free of cracks or blockages
• Consult the Weil McLain installation and service manual for wiring and mounting specifications
• Installation should be performed by a qualified HVAC/R technician
