This applies to our low pressure EasyFlamer 1 burner stoves, both propane and natural gas. Behind the front power adjusting knob and under the burner pipe and front cover there is an electronic ignition valve assembly. The electronic ignition function can be unreliable and its ability to ignite can vary from unit to unit and under different weather conditions. We advise to always have a manual BBQ long nose igniter handy when the electronic ignition function is not working. Please be aware that this product shipped from us may not have a functioning electronic ignition. In this case the stove is functioning as a manual one.
