Viessmann 7835169 Ionization Electr. R-22 High-Temperature Durability: Constructed with robust

High-Temperature Durability: Constructed with robust materials to withstand the rigorous environment of furnace supply plenums

Key Benefits for the Contractor: Dual Automatic Operators: Meets strict safety codes by providing two layers of gas shutoff via the solenoid-operated first valve and diaphragm-operated second valve

Optimized Superheat Control: Ensures the evaporator operates at peak efficiency while preventing liquid refrigerant from reaching the compressor

Operating as a close on rise thermal switch

the EA36UZ154 handles a maximum operating pressure of 650 psig

Viessmann 7835169 Ionization Electr. R-22 High-Temperature Durability: Constructed with robustThe Viessmann 7835169 Ionization Electrode is a critical flame sensing component engineered specifically for high capacity Vitodens 200 W B2HA condensing gas boilers. Designed to handle the rigorous thermal demands of the B2HA 399 and 530 models, this electrode provides the millivolt signal necessary for the burner control unit to verify flame presence safely and consistently. This kit includes the required electrode gasket to ensure a gas tight seal
