New Braunfels Bandera Smoker instructions for use

Question

I have purchased a second hand New Braunfels bandera Smoker here in Queensland, Australia. There was no intructions with it and the people that it was purchased from also did not use it or know much about it. It is very different to smokers we have here in Australia, but i am keen to get it going. Any assistance would be grateful. Email address is [e-mail]
