We're looking at getting a small unit for a occasional use. We've been told that it should be installed indoors, in combination with a flue. We're thinking of installing it in an alcove right outside the back door. The area has a roof and 3.5 walls - so it has a huge opening. Do we still need a flue then? I'll try to draw up the plan of the small area, approx 1.5 x 2.5 m

Something like that. The top of that ascii drawing is the back door, which is closed most of the time. That huge gap is full height, stepping out to the back deck. Is that sufficient ventilation for occasional use gas water heater?
Cheers,
