I do HVAC work for a living and found this toy works great to check stove temps. It has a Lazar dot that you just point and shoot, you can pin point any part of your stove or flue. These pictures are of my new Osburn 2200i one is the glass temp. and the other is the temp. of the air coming off of the blower. You can get one at any HVAC supply house or at Grangers for around 75.00. ( Kinda cool aint it!!) The last picture is the fan switch that I installed. When I come home for lunch I shut off the switch and reload the stove then its in auto mode the disk will cool of enough with the door open and the fan will shut off. After she comes back to life I can flip the switch and override the disk (seems kinda of slow to make) that way I can leave the house and know that I have air going over the stove. I cant imagine this thing running without a blower.
