Description
The Rheem-Ruud 42-105443-01 Gas Pressure Switch is a safety control component used to installed gas flow and ensure proper sludge conditions during burner operation. It operates by detecting normal pressure levels within the gas or combustion circuit and opening or closing an electrical circuit when readings fall outside the safe range. It is installed within the gas train or burner assembly where accurate pressure sensing is required. By verifying correct before and during operation, it supports preventing unsafe ignition conditions, improves combustion, protects system components, and supports consistent heating performance in HVAC systems.
