I have a gas fan control model 4021-229-B rev c...yes, ollllldddd...like it's owner...was wondering if i can convert it to have a batter backup, but can't find the spec sheet on this model....like amp and wattage? do they run on a standard amp and wattage where i can just use the current fan's spec ? any ideas would be greatly appreciated.
 
What unit is the blower in - Manufacturer & model?
LOL! I shoulda included that obvious info...muh bad...the fan is hooked up to a heatilador direct vent fireplace. the fireplace has a battery back up to start the pilot when the power was out, but the fan doesn't run on these DD batteries. I was looking at the setup and wondered if i can sub the fan's power supply with a battery/portable source of power instead. ..ok...as i was typing this, i got the answer from another source...it looks like i have to provide a consistent 110Amp hard wired power to the neutral box which the fan control is connected to for the fan to run. soooo....either i hook it up to a "generator" per the dude who answered my question, or it no worky...aside from a gas run generator, any ideas on how i can get this kinda power on battery?
 
"Wow Provide that type of power out of battery will be very difficult "provide a consistent 110Amp". What size wires does this use? Now if your taking Volts that is different. I get 12 hours out of my AIMS 1250 to run my Pellet Stove for Outages. It uses two 100ah Batteries. If you need more get Inverter Generator. I like ones that run on Propane. Propane does not go bad like gas will.

Yeah...the dude pretty much says no battery can provide that kind of amperage. i think hooking the whole thing to a propane generator may be the way to go...or solar backup battery like one of those tesla wall or something like that...sigh...was hoping for a simpler and cheaper solution LOL
 
If you meant 110 volts AC then you can easily hook an inverter to a battery to get that. Hard to say how long the battery would last.

I get 6 hours of 100ah battery. I have 2 of them for 12 hours. I run it in Manual at 1/2 speed fan. Only did it once so far. T = (N x AH) / (C x 10) (broken link removed to https://resources.secamerica.com/how-long-will-my-pellet-stove-run-on-a-battery-backup)

P.S. to run a motor on an inverter, it's best to look for a "pure sine" inverter. They are a bit more expensive than the "modified sine" aka square wave inverters. The pure sine will be more efficient and not burn up your fan motor.
