To be honest, I initially identified this as a Milwaukee because of the red. However, Milwaukees don't have the round, hair dryer shape, and they're actually not red very often, either. Searching the 'net, I found heat guns with a shape (and color) more like what was shown.
This one is made by Master Appliance, although I don't know that it's the one Norm used. Since it only appeared a couple of times I'm not going to be anal about really figuring out whose it was. I just wanted to provide a reasonable representation of what the tool looked like.
Most of them seem to have been made by a common manufacturer and then dressed out in different livery (the Bosch at left, for example seems identical, except for a blue body). Don't let the angle of the plate fool you—it's adjustable. In fact, I suspect it's removable. In the appearance in Episode 1906, it wasn't attached at all.
