Product redesign Engineer Needed

I designed the portable steam sauna. There is a steam generator that boils the water and creates the steam. The way it designed now is the fabric sleeve that connects to the fabric steam canopy with another end covers the steam generator. The steam can freely go into the canopy. The issue is that because of the very high temperature the outside of the steam generator is getting melted and destroyed. I need to redesign the way the steam goes into the canopy. I tried to use a tube that goes directly from the steam generator into the canopy. In this was the hot steam builds u the pressure and the hot water sprinkles into the sauna and burns the person’s feet. I need to design the safe, effective and inexpensive way to deliver the steam into the canopy. Please keep in mind that this is a foldable steam sauna. The structure cannot be too big to prevent the sauna to be folded and put away into carrying bag. Also I cannot send the saunas back to manufacturer, it is too expensive. I would have to use your design to locally implement the structure. I have tubes and a connector that can connect the steam generator directly to the sauna. You can use it in your design. Please view attached pictures.
