Wood/oil burner duct servo?

[chopped]

Hello. Yes Im back with another stupid question.
Here is my situation. I have both a wood furnace and a oil burner hooked up for forced hot air.
The wood duct is straight run and the oil comes in at an angle. Presently I have a 'damper' in each and choose which to open and also to close during operation.
they open manually with a homemade lever. I would like to somehow 'cheaply' have them so one could open and stay open when in operation.Basically when I switch the power for the oil then it would open the damper for circulation.
Anything Ive found is more money than id like to spend. And im looking for something basic. Im just not sure what to look for , what names or phrases to use.
Any help would be appreciated.

Here are some keywords you might want to look up to make it work.

-actuator
-damper actuator
-damper linkage
-spring return damper actuator
-24v R.I.B. (relay in box)

I'll attach a cut sheet form the company I work for (Johnson Controls). The M9208 has 70 inch pounds of torque. Thats about the smallest one we have. Kele company would probably be the best bet for buying one or two. They have the RIB relays also if you need one. If you are just going to have a selector switch, you may want to use 120 volt actuators. The possibilities are endless as far as the different degrees of automation. I'm guessing that the actuators would go for around 175 bucks through a distributor.
You can see from the cut sheet that this actuator is designed to apply torque to a pin sticking out of the duct. It's probably the easiest way to go.

Thanks for the ideas. Its all in the wording.

I have pretty much the same setup and use a 10" backflow damper much like this ,, Fantech RSK 10 Backdraft Damper 10" Duct: Amazon.com: Industrial & Scientific

I would go to the Junk Yard and buy a couple 12 VDC Door Lock Actuators out of some junker BIG OLDER Fords Lincoln as they seem to have very strong linear actuators that are powered UP and DOWN mechanical versions. I have a few out of my old Thunder Bird that takes about as much to hold them as you could think with a stroke that is 2~4"...

I think backdraft dampers are a fantastic idea. But as an electrician, you shouldn't be suggesting non electrical solutions; it's bad for business.:laughing:

My heating system is complicated enough already,, Warm air with 10 zones for the heat through a Mastertral Mark X and a powered dump zone just for the workshop,, along with a 2 zone warm air solar setup,, and yes the wood furnace with and electronic readout in the living room so I can monitor the stack temp from up stairs,,, The wood furnace I wanted to use the KISS method on just in case neither of my generators were to start while I'm not home..

If you know a guy that does pool service see about getting an old electric control valve. You can adjust how much rotation they have with internal limit switches. I have my air compressors set up with these, operating ball valves, to shut off the air remotely. Jandy is the trade name on mine.

look up Oil Vent Damper by field controls,, Thats what I have
