Combustion air damper

I posted earlier for oil tank help and associated with the same boiler I would like to install a comb. air damp. I would like wire it to my Honeywell R7184B controller I have already purchased the damper and wanted to know if anyone had any thoughts on how to connect this thing.
I would like to run it 24 Volt and through the controller saftey.

Rob, I don't believe it's advisable to install a damper on an oil burning system... others will likely be along shortly to explain why .

My main thought was to provide adequate combustion air for the boiler. I am finishing off the Mechanical room and it is going to have a metal entrance door no louvers.
Why not on oil?

Rob, maybe I mis-understood again...

You DID say combustion air, and that part didn't sink in.

Do you mean a damper on the flue pipe ?

If you are looking to provide combustion air, you can run a piece of dryer duct from the outside, and terminate the duct in a 5 gallon pail. The pail will provide a 'heat trap' and only flow when there is an air demand.

If this a damper that is needed to provide external air to the boiler room, it probably needs to be interlocked to the burner like the UL approved appliances that are made for that purpose.. If it affects combustion, it is NOT a DIY item.

Yes combustion air not a flue damper.
I already have the 24 volt actuated damper and would like to run it thru the honeywell controller.
I just need a wiring dia. for the 24 volt terminals that are activated for "demand"

Combustion Air Damper

Rob,
Is there some sort of interlock on the damper which will not allow the burner to fire unless the damper is open? If not, you really need one.

Yes there is a 2 acessory interlock for just such a device.
I am not making this an air tight chamber but a little extra would help.

Wiring

If you are going to break the thermostat connection, how is the burner going to fire or even bring on the venter? Can you provide a make & model of the damper? Maybe I can find something online.

Rob,
The link you provided was for the venter. You must have one big boiler to require that big of a venter. I wanted a link or info on the damper, sorry if I wasn't clear. I gotta get some shut eye. Not used to 22 hr days anymore. Let's pick this up late morning or early afternoon.
