I do have DVL pipe in my flue setup as i live in a mobile. I was wondering if anyone has an opinion on the probe thermometers that are sold to measure flue gas temps or are they a waste of money. I ask because the guy I bought it from said don't waste your money. That was at Woodman's Parts Plus.com.The store is close by in . N.H...So i was there in person to pick up my metal cricket which this same person did hand make. By the way the cricket was a first class job and made out of 14ga galv steel. So i guess he knows his stuff..
