Why the gas hob cannot igniting or it take a long time to ignite?

(1) No gas supply --If the gas hob cannot igniting,please check whether there is gas supply. Turn on the gas cylinder and make sure the flexible gas hose is not blocked.

(2) Spark electrode was damaged ,dirty or out of position-- The spark electrode produces spark to ignite the gas, please make sure it is in good condition, clean and in right position(the distance between the spark pin and flame hole should be around 3.5-5mm).
