| sorry i used the wrong words... i meant heat gun... those that u put in lighter fluid from a pressured can. it is not even hot enough to melt the pipe solder let a lone the brazing. trust me i know how to solder and braze the pipes...and not only that, if you apply too much heat to the valves, you can melt the rubber o-rings (you put a very wet cloth over them)... regarding catching on fire... that is not likely in my opinion since i have changed many 40-50 amp breakers where they don't trip and the wire melts inside the air handler or the condenser... if something catches on fire it would be just the cable plastic but that would be fir just one second... i believe the engineers have thought about this when they design the units. thanks though. |
