Hello , I now have to use an extension cord (outside ( to my 1400 smokintex .. when i smoke at night at times i get concerned about weather because where i plug my 1400 in the extension cord its outside .. im concerned about it raining at times .. my question is this .. should i get a longer extension cord to be able to plug it to the 1400 inside my back porch ? or is there a good way to waterproof where i plug the 1400 to the outside extension cord ?

In advance , I thank you for your help / reply ..

Regards , Brian
