SWEAT Susan!
I did get my roaster installed today! 3 hour project to get the hole cut in the wall, 220 electric run from the breaker box, gas line run, and BANG! I'm working on trying to make my pics smaller to be able to post,,,,, I've tried twice and to no success yet. I wish I was a computer nerd at times! Patti has tried to work her magic on the phone and I tried with an app on my computer.... DUH, no success yet. I'll keep trying and if all else fails I'll send to Cammie to post.
In a nut shell, the pipe is double walled through the wall. Nice defuser on the outside as a vent/hood. The installers did a PROFESSIONAL job! I am very impressed. Safe and sound in Freeport, OHIO! I roasted three 2.5# batches and I have a lot to learn! Still tooooooo fast! The last roast was 11 minutes and the rate of rise in the temp was steady. I believe my solid steel drum is touchy!!
