I guess I did not make my self clear. No surprise there. Presently inside the heater I have all the wires going to the fan connected with wire nuts and electrical tape over the nuts. These connections are in the flow of the cold air. What I am worried about is over time the tape drying out due to the air flow and the nuts falling off then roasting marshmellows on my house as it burns down.

I don't know it there is a code issue here, but I am asking all of you knowledgable elctrcians "How would you do it in your house?"

My thoughts, J-box inside the heater, J-box outside the heater(If the wires are lock enough) or as Trumpy suggests a terminal strip in the heater. But that would have to be in a box wouldn't it?
