OK, so I had to get my LeisureLine Pioneer with Power Vent through a pretty rigourous and difficult inspection/approval process in my town. In the end my design was approved. Plug the power vent into a battery backup (an APC UPS from Staples, $109) and plug the WMO-1 safety switch (which feeds the stoker/blower/combustion fan) into the regular utility or non-battery outlet on the UPS. I am attaching the final approved wiring diagram.adirondacklady wrote:Ok, I understand that the fire goes out within 10 minutes if the power goes out. Here's another question: If there is no power to the powervent, how are the gases and exhaust drawn out of the house during that 10 minutes that the fire is still burning? Does it not come back into the house?

In my setup running .06 draft the fan will run between 60-83 minutes. It's far longer than the fire will burn.
