1. No gas is emitted during ignition.
While operating the "fire test" button, an open flame can be used to ignite at the ignition of the igniter to confirm whether or not gas is ignited during ignition.
If there is no gas injection, check the main control board and solenoid valve indicator according to the gas path fault check and elimination method in 15.3. If the main control board and the solenoid valve indicator are normal and there is no valve blockage, there may be a blockage of the gas nozzle on the igniter. The method of diagnosis is to loosen the nut under the adjustment knob on the igniter and place the knob in the water to see if it is ignited during ignition. If there is gas here and there is no gas in the igniter fire, it is definitely blocked by the gas nozzle. The gas nozzle hole is small, Ф0.4mm. The solution is to use a scrap steel saw blade to grind a slender small tip and use it to connect the small hole.
2. Is the ignition control correct?
Whether there is carbon concentration on the spark plug will also cause the spark plug to not catch fire and need to be removed. Next, check the high voltage packages connected to the spark plugs, as well as their interconnections and connection plugs. The input of the high voltage package should be DC3V (two ordinary batteries) voltage, and the two output lines of the high voltage package (two lines separated by 2-10mm) should be able to generate spark discharge, otherwise the high voltage package will be damaged.
3. There is gas during ignition, and the spark plug is also ignited, but still cannot ignite.
The main cause of this phenomenon is that the gas concentration is too large. The gas concentration is not suitable, and it is often impossible to ignite normally, especially when using gas such as gas or propane. At this point, you need to adjust the "adjustment knob" to change the gas concentration to solve.
4. The spark plug does not catch fire when igniting.
When igniting, there should be obvious discharge spark between the spark plug and the igniter body, which can be clearly seen, and a clear spark discharge sound can be heard.
If the spark plug does not ignite, first check if the main control board ignition indicator lights up for 1-2 seconds when the “test” button is operated to confirm whether the ignition control of the main control board is correct.
