Hello all. I have a older Regency CL1250 Alterra flush mount fireplace insert and with the fan running and a block of plate on a centrally located chimney in a house that was built to be heated by that fireplace. It does a very good job to cut way back on the amount of fuel oil I’m burning each winter. I live in a spot with fairly reliable power but was thinking about fan back up options in case of power outage. Does anyone know if the outlet inverters for the bigger m18 or the ryobi 18 even would power the fan? I have batteries and tools for both. The M18 has the bigger batteries. 9.0ah. Does anyone know if something like this would work to power a stove fan like this. Has anyone been able to run a fan with one?
