Up for sale is an older Dayton 30,000 BTU heater - NG. It has a new heat exchanger but needs a fan time delay switch. I fired it up to make certain all was good and the fan just kept on running. That was about 15 years ago and never touched it since. I am now moving and don't want to take it with me. I found the time delay switch on eBay for around $55 so how about $125 OBO for the unit itself. Thanks for looking.
