I was takeing a mod furnace class and the instructor was stressing not to install a bypass humidfier to this type of furnace. this bypass would throw off the ecm blower as well as the temp sensers. Has anyone had any problems or have installed bypass humidfiers on these units? I did install my first mod with a bypass back in november and had no call backs or issues.
I decided on next weeks mod install to go with a fan type humidifer.
