Jeff,
That was exactly my earlier concern as well. However, upon close inspection, I came to realize how safe the system is. This installation incorporates a stainless steel hood (not unlike a Viking gas range) secured independantly over the top of the bulkhead-mounted heater. The fume extractor is side-vented through the galley teak interior paneling and exterior FRP by way of an exterior-pitched metal sleeve, fitted with a circular metal damper at the outlet. The damper can be screwed in (inside/outside control) when sailing in foul weather, or out when in use.

I was very impressed by the quality of installation . . . I design high-end buildings, like you, and have grown accustomed to quality craft & materials.

My propane oven/cooktop is vented via an operable hatch just overhead and as previously mentioned, the regulated cylinders are on the exterior, in vented lockers. As you know, propane sinks and could present hazards in faulty installations.

Edit: I forgot to mention that Junkers was bought by Bosch who continues to use the Junkers name on some of their high-end products.
