Hi, I'm Wayne.

I'll be assisting you with this issue today.

Thank you for coming to Just Answer

Your Question is as important to us as it is to you.

Just Answer might prompt you for a phone call,

that request is not from me and is not necessary.

Do you get smoke from the stack when you crank it over ??
