after the power and gas supplies have been safely shut down.
The pilot flame
cannot be ignited.
The pilot flame is on
but the main burner
cannot be ignited.
When the gas supply
is shut off, it
produces a
light-back sound.
1. The gas pressure is not enough.
2. The nozzle is blocked.
3. Connection of the
thermocouple is loose.
4. The thermocouple is defective.
5. The gas control valve is
malfunctioning.
1. Adjust the relieve valve to
get a proper pressure.
2. Unblock the nozzle.

Produces red flame,
and it emits black
smoke.
1. The diameter of nozzle does not
match with the gas supply.
2. The damper is too small.
3. The gas nearly runs out.
4. The gas ingredient reduces
the gas flow in gas peak demand.
1. Adjust the nozzle diameter.
2. Adjust the damper.
3. Replace the gas.
4. Decrease the gas flow
and increase it after the peak
demand of the gas.
