As the combination gas valve and manifold assembly, this kit controls all gas flow into the burner section across both low-fire (Stage 1) and high-fire (Stage 2) operation. When this valve fails, symptoms include a complete no-heat condition, repeated ignition lockout faults, or a furnace that fires briefly and then shuts down.
