Jerry Simon Posted April 29, 2020 Report Share Posted April 29, 2020 The gas-fired furnace and hot water heater are located in a garage closet. Zero air-intake source from the garage. Took me a while to figure out why the furnace's exterior air intake flue pipe had been *tee'd* with an open-end pipe stub. Do you know why?
