In this edition of the Btu Buddy series, the dispatcher calls Bob first thing in the morning before he leaves his home and tells him that a customer with a gas furnace has a strange smell in the house. Bob tells the dispatcher to call the customer back and have them turn the furnace off until he can get there, within the hour. It is very cold outside, about 10 degrees F, but the customer has two fireplaces that can keep the house warm enough until Bob can get there.
Bob arrives and the customer explains that, when the furnace is operating, he smells something peculiar and he's concerned. It smells like his gas grill when it first starts up.
