I use an expensive and fully lockable cable which holds the flapper shut
because I fear the same problem. That shuts off the fire inlet at the
duct. I draw the air from a low risk fire area, but not a perfect
solution.
If I had regs requiring a stop valve, I would make it from stainless as
a box with a flapper in it. Aircraft Spruce has a heater valve which I
would use as a guide. Theirs is made of aluminum. Let's face it, if
the aluminum melts because of a fire, you're in serious do do.

I have looked at your heater and it is in principal the same as mine
and many others. That is taking the warm air off the rear of the water
radiator. Mine is fitted but not operational (fire wall phenolic is
bolted over the outlets of the SCAT tubes)
The reason for this is that Francis Donaldson (LAA) insists on a fire
stop valve at the point were the tube passes through the fire wall. One
builder, Mike Parkin, has made up some very expensive petal valves to
achieve this. See attached. I am still looking for a cheaper and
simpler solution to these valves.
Obviously US regulation is not the same as ours. What are your
thoughts on a) the need for fire stop valves and b) a simpler cheaper
way of achieving a fire stop?

Jeff,
Working on that with better access for fuel tank, controls, mods or
repairs. The cockpit module is heavy and requires a lot of help to get
it in right and it is very time consuming to build for the novice, and
for the company to construct.
Keep the ideas coming.
Go to my website and download the heater. One inch tubes is all you
need really to keep the plane warm.
