Tell them to build you a dual coil out of 2 2ohm coils as f1vefour said thats gonna be a 1ohm setup... Its safe and its a good beginning with an igo...
Theres nothing dangerous about your current setup... Unless youre a dummy (i doubt that you are)... But you should check the ohms on a regular basis to make sure it stays where it is.
And if you experience the mod getting hot you should get the battery out of it to determine if thats the heat source (you wont doubt it) if that IS the heat source put it somewhere where nothing can catch fire and do it fast... When it cools down check to see if theres any harm done to it and check the charge on it...
The atomiser itself can get pretty hot because of the coil and transfer heat to the mod itself, but in this case the battery wont be as hot as the mod and the atomiser will be the hottest part
