1. The manifold distributes gas from the gas valve to the burner.
2. To provide proper quantity of gas to burner in each stage.
3. There are 3 zones within the manifold, to ensure efficient combustion
operation.
1. Dust deposit on the manifold.
2. Gas leakage from a failed manifold.
3. Ignition failure.
4. Imperfect combustion.
1. Visual inspection: Connection and/or breakage of wires.
2. Voltage check: Check range of voltage shown below.
1. Yellow – Yellow : On : DC 83 ~ 120 V, Off : 0 V
2. Red – Red : On : DC 83 ~ 120 V, Off : 0 V
1. The burner cannot receive proper gas flow from the manifold, which can
cause poor combustion in the combustion chamber. In this case, the
flame rod will detect an improper flame condition and the PCB board will
take safety measures.
2. Gas leakage from the manifold.
