The EMPIRE INDUSTRIES R1769 is a vent safety switch rated for operation at 210 degrees F, designed to monitor flue gas temperatures in vented heating appliances. This switch serves as a thermal limit control that interrupts the system circuit when vent temperatures exceed a safe threshold, helping protect the appliance and surrounding structure from overheating conditions. It is a direct-replacement component intended for use in gas-fired heating equipment, installed by qualified HVAC technicians or gas appliance service professionals.
The R1769 is suited for residential and light-commercial vented heating applications where vent temperature monitoring is required. It is referenced in conjunction with model designation GW-50-3 and GW-50-4, indicating fitment within that product family. This type of component is typically found in wall heaters, furnaces, or vented room heaters where flue safety is a code-required design element.
Referenced for use with EMPIRE INDUSTRIES model designations GW-50-3 and GW-50-4. Verify appliance model and control wiring before installation.
Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional. Shut off all electrical power and close the gas supply valve to the appliance before servicing any limit or safety switch components. Verify the replacement switch matches the original temperature rating and terminal configuration before energizing the system. Applicable work should conform to local mechanical codes and the appliance manufacturer service documentation.
