The WESTINGHOUSE 1010035 is a furnace twinning kit designed to link two gas furnaces together so they operate as a single, coordinated heating system. Twinning allows two matched furnaces to share thermostat signals and run in sync, increasing total heating capacity without replacing the existing equipment. This kit is used by licensed HVAC technicians during installation or retrofit work where a single furnace cannot meet the required load. It is specifically engineered for use on the KG7S furnace platform.
This twinning kit is intended for residential or light-commercial applications where parallel furnace installations are required. The KG7S furnace is a gas-fired, induced-draft unit, and twinning two of these units requires a dedicated interconnect kit like the 1010035 to ensure proper sequencing and control logic between both systems. Installation is performed by a licensed HVAC technician familiar with multi-unit furnace configurations.
Designed for use with the KG7S furnace. Consult the furnace installation manual and this kit's documentation to confirm twinning eligibility before installation.
Installation must be performed by a licensed HVAC technician in accordance with local codes and the manufacturer's installation instructions. Shut off all power to both furnace units at the disconnect or breaker before beginning any wiring work. Follow the interconnect wiring diagram included with the kit exactly — do not substitute generic wiring methods for a twinning application. Verify thermostat compatibility and control board settings on both units before returning the system to service.
