Bowen water heater help

[marblesyoga]

I have a '68 Overlander with a Bowen water heater. I recently purchased it and am working on getting the water going. My water heater is missing a piece. I can't find a manual for this water heater. It is a model G10TF4R, 10 gallon, 10,500 BTU unit. Here are a couple of pictures. Could someone tell me what piece I am missing and maybe how to find the piece. Thank you. I'm almost done getting everything working on my Airstream and can't wait to take my first shower. Oh, also something else: We have the original 'vinyl covered cardboard' shower curtain. Is anyone familiar with what to use instead of this. It seams awkward.

Your missing the burner and more. Enough that your not going to find parts or want to pay for them if you do. If it were me I'd replace it with a new Atwood (they bought out Bowen many years ago). Here's where we purchased out 10 gallon and there are many other sources (a lot of folks have purchased from PPL Motorhomes).

If you take the vinyl folding shower screen off - don't pitch it - someone here would love to have it. Good Luck....
