Some home inspectors and HVACR technicians want the drain to be insulated either to cure an actual observed wetting problem OR because they're making their own, probably unnecessary, interpretation of one of the model energy codes. I want to know if it is ok to run 6', sloped of course, out from the unit before putting in the trap. My "guess" is that the reason those pumps are excluded is an effort to avoid leak and mold damage liability. If the condensate lines travel off the service platform and disappear in the insulation, thats fine.
