My heater will sound like its starting up fine with the fan and all and the status/burner light on top will go up from bar to bar but then when it gets to the last bar it clicks off and the light starts flashing. My 7 year old son may have been messing with the on/off switch and pressed it a bunch of times? I tried pressing the reset switch on the lower right button side and nothing helps! When I look in the little viewing window in the front there is no flame whatsoever. I didn't know if there was some kind of pilot light that needs to be lit or if it is flooded or what? No idea? Please Help!!
