Hi, I just installed a used Omar Housekeeper 3000 to replace my Nutone CV350. I upgraded the wiring and installed dual exhaust pipes, each with a muffler and vented outside. The suction is great but I noticed that the exhaust pipes and motors get very warm, hot even. The unit uses two Amatek Lamb 115334 motors. Is this normal? Mark in Seattle, WA.
Yes, the exhaust and pipes will get hot. That is normal. If the pipes melt, that is not normal. If the exhaust runs are separate and no longer than 15-20 feet you will be fine.
