Here are some pictures of my Pro 400.  Hope this helps.

That area doesnt get hot per say.  All of the cold air is being blown in right at that very spot where we see the problems.

Maybe some type of thin refractory or a coating would stop the issue.  But its something to think about and try to figure out.  I hate he had this issue but seems like if we can figure out a fix for it he'll be in great shape.

Could a piece of 409 stainless be used there instead?
 
If engineered properly the expansion differences between the stainless and standard metal could be negated.

Thanks belknap so yours is fixed already I see, how thick is the piece of metal they sent you compared to the old burnt out piece?

[Jwood]

Oh scratch that last post yours never burnt out.

Scott will the new mount need to be welded on or is there enough left to screw it on? do you think using something like this will affect his warranty?

def would not affect his warranty....   There is plenty of good metal left on his to screw the plate on

The repair kits are 304 I think....

Yes I know Scott I corrected myself before you posted.

I do have a question though as far as screwing that piece of stainless they give in the fix it kit, I can see how you would get the screws in on the fan side but how do you get the ones that go on the side? Maybe its not as tight of a squeeze as the picture suggests?

[Belknap]

I think you would have to take the exterior sheathing off.  I can't see getting anything in there on the side to install the self tapping screws.

[Jwood]

Gotcha! It sure looked like a nightmare getting a drill in there.

Didn't see that til after I posted,  I was scrolling through

[Scott7m]

This area altho it's not supposed to get hot can catch fire if creosote nearly plugs it up, it's important to inspect this area a few times a winter

[Jwood]

No problem Scott, are you talking about pulling the fan off and checking inside there?

[Scott7m]

Yep, just takes a couple mins once you do it a time or 2
