I'm preparing to install a Pocono with a power vent in a 71" wide area.
If a power vent motor fails when I am not home but the Pocono keeps running, what happens? Will the gases present any kind of fire danger? Will the house fill with CO? Is there any kind of safety that cuts power to the Pocono?
It seems many people here use power vents. Am I missing anything basic regarding their use?
Coalnewbie had a great explanation. The fume switch also protects if the pipe were to fail as well. This is why I prefer the PV method of artificial draft vs direct vent. With a PV all pipes leading outside are under negative pressure. With a direct vent all pipes after the vent are positive pressure and no reliable way of monitoring the system between the DV and the outside.
