Heating Damper

Hello all!


I have a damper (I assume its a damper) on my heating exhaust. There's one pipe that goes to the chimney, and in between the force hot air system and the oil fired hot water heater, is a damper. The damper opens when one of the units is on, and gravity closes it when everything is off. The damper lets in fresh air from the surrounding room to help assist in air flowing up the chimney.

The damper has aged to the point it no longer works, ever now and then it will jam shut and the hot water heater will shut it self off as the exhaust begins to back up.

I cant find this puppy ANYWHERE. It's 7 inchs round, it has a counter balance weight on it that can be adjusted by spinning a screw. I used to set it until it was just about to fall over, and the air vacuum from the units would take care of the rest - gravity then closes it.

Any idea where I can find this online?

Thanks!

That's a draft regulator, it should be set with instruments.
Google that and it comes up.

Also called a barometric damper. Field Controls is the leading manufacturer. PEX Supply surely has them.

Blake, I'm a bit confused by your description...

in between the forced hot air system and the oil fired hot water heater, is a damper
What exactly do you mean by 'in between' ?

Can you post some pictures of what you are looking at?

Bio metric Damper definitely got me closer to what I need.

by "in between" I mean...

I have a force hot air unit with exhaust, then I have a hot water heater with exhaust, they are connected to the same 7 inch exhaust tube that connect to the chimney.

In between the two units, T'd off is the damper.

Bio metric Damper
Not " BIO metric " ... BAROMETRIC , one word.

Is the hot air furnace a GAS fired unit? and you said I think that the water heater is OIL fired? Or are they both oil fired?

Something doesn't sound right about your installation, I'd like to see a photo of the flue piping is you can post one.

Do you have functioning Carbon Monoxide detectors in your home?
