Topic: IR2 dryer duct fire, possible? (2 msgs / 62 lines)
1) From: Stephen Carey
Hi, all.  With all the recent talk of fire potential and safety 
protocol, I got wondering about my IR2 dryer duct hose which goes to 
the ceiling fan from the machine.  Now, I will be using it much less 
often now that I have my Behmor, but still will be using it.  I 
believe some coffees may taste different roasted in it and I may 
prefer those.  I plan on experimenting, and if correct, it gives me 
one more way to get the roast I want for certain beans.
Anyway, a lot of gunk builds up in the dryer hose.  I have replaced 
my once, though it may not have been necessary, but it was "icky" (my 
professional term for how it looked, smelled, and felt).  Now the fan 
is sucking up the hot air and seems it would keep any oil fire from 
starting, but is that true?  Should I change my dryer hose as 
specific intervals of roasts or based on how gunked (another new 
word) it has gotten with smoke oil, etcetera?
I have never heard of this as being a problem and didn't see anything 
in the archives, but still wondered.  It's winter, I roast inside, so 
I want to be safe.  One day, when I have graduated to outdoor drum 
roasting I am sure I will have other questions which may seem silly, 
but for now it is me, my IR2 and my very lovable Behmor - I can't 
wait to roast some wonderful Costa Rica Vino de Arabia for my mother 
in the morning on that wonderful machine.  I just follow number 3, 
section 5 of the instructions very closely.  I keep the pathway 
outside clear, plus have a fire extinguisher.  Sounds kind of like 
overkill, but once you have lost a home due to a neighbors kitchen 
fire it is easy to get a bit paranoid.
Thank you for the thoughts on the dryer hose.

It *shouldn't* be a problem, as the way the thing connects, it's kind of 
grabbing a lot of surrounding air too isn't it?  Sorry I don't have mine 
hooked up but have seen it and how it fits and kind of think I know how 
it hooks.....  anyways...
There is some cooling in there, BUT, if as you said it is getting icky 
with oil residues etc, that might in the long term pose a problem.  
Perhaps not with a fire, but with lint sticking from the normal dryer 
pumping through there and eventually restricting / clogging your flu 
pipe to the outside.  If it's running residues through there, stuff will 
eventually stick....
Another thing to consider is, the dryer hose itself, they do sell all 
metal hoses, it's kind of like an accordian aluminum hose.  Get one of 
those, that won't burn, and if it does somehow smoulder in there, it's 
metal, it won't melt through like a plastic one might.
