providing the thermal protection necessary to maintain efficient heat transfer and prevent heat loss through the jacket

the Fasco D0563 is a shaded pole motor and does not require an external start or run capacitor

This ignition module features a 30-second pre-purge cycle and a 4-second Trial for Ignition (TFI)

2 mm (1/4")

This makes it an essential component for low water cutoff (LWCO) systems and pump-up/pump-down sequences in boilers and food service equipment

Viessmann 7828718 Electrode Block R-407A providing the thermal protection necessaryThe Viessmann 7828718 Electrode Block is a critical genuine OEM ignition and ionization electrode assembly specifically engineered for Viessmann WB1B and B1xA series boilers. As a dual function component, it integrates both the boiler ignition electrode for consistent burner start up and the ionization flame sensor for real time flame rectifying and monitoring. Technicians servicing Vitodens 100 W units will find this block essential for resolving
