a ne ative pressure is created in the room. If a as apĆ
pliance is operatin in a room with ne ative pressure,
the flue products can be pulled back down the vent
pipe and into the room. This reverse flow of the flue
as may result in incomplete combustion and the
formation of carbon monoxide as. This toxic as
mi ht then be distributed throu hout the house by the
furnace duct system.
