Query: Electric Brinkman smoke cooker

We purchased a Brinkman Electric smoke cooker and find the door opening to insert chips is much too small and there is no way to regulate heat so we tend never use the darn thing anymore. We would like to find a reostat or a way to use a thermostat so we could enjoy using this thing. We would like to be able to make jerky or smoked salmon with it.
