That's what I'm trying to figure out!

The chimney must extend some distance higher than anything
with in some distance of the chimney.

The chimney is a good five feet above the roofline and the sheet metal
enclosure is another 2 1/2 to 3 feet above that (which is just about as
high as the spark arresters).

Plus it's a clay tile roof so there's not much nearby to catch on fire.

That should be OK. Three feet above the roof where it comes out Two feet
above anything within 10 feet.
