[Amps] chimney material suggestion GI35b

[Will Matney]

Manuel,

It would work if it doesn't touch the heat fin ring itself. It needs to 
be about 1/4" larger I.D. than the O.D. of the tube. The air temp is not 
that hot, but the max temp of the fins is hot enough to melt the PVC. 
I'm working with a company now to supply flame-proof fiber tubing for 
this. I ordered a few samples but haven't tried it yet. I ordered some 
just large enough for a 4CX250B.
