Boiler with compression tank, want to add B&G Airtrol fitting.

That's quite the offset piping

I think the relief valve should be mounted in a vertical position?

Just to update you all. I finally got a chance to plumb the B&G Airtrol into my boiler properly with 3/4" pipe. It's been working great so far for a week. I'd say this has to be the best this boiler has worked since new. Thanks again for all the help and suggestions. Here is a couple pictures of how I piped it to the tank.

Good morning OldBoiler65,

Bravo, congratulation's to you for an excellent installation and repair to your boilers air management system that is plumbed within its existing piping risers that will provide you with trouble free air management.

Seeing the flanged gasketed pipe connections in your basements boiler piping illustrates true craftsmanship and thought regarding how your heating system was designed and installed.

Gaskets for flanged piping are still made and available, do not let anyone tell you these gaskets are not available as they are made by the A.W. Chesterton Company of Groveland, Mass., which has a nationwide distributor network.

As long as the larger air bubbles and microbubbles can escape the boiler steam chest they will waddle up the riser pipe to the ATF-12 Airtrol valve and the cool denser water in the base of the steel compression tank will fall, drop, sink back to the boilers steam chest waving so long to the rising air bubbles that are riding the hot water highway to the ATF-12 Airtrol valve.

Thanks for bringing sanity back to your homes heating system that will provide you smooth even quiet heating and eventually no air bubbles to your heating plant.

I agree, I thought it would be alright for now since the manual for the boiler shows the relief mounted horizontally.

@leonz Thank you very much! Yes, it is a very nice system that was installed around 1920. The American Standard G-210 boiler was installed in 1965 to replace the original coal boiler. I brought it back from the dead after it had sat for possibly 20 years not working. Then I found that I could not get the air out no matter what I did. After browsing the internet, I found out about the Airtrol and with much help from this forum I found it had some issues with the piping. So far, I'm really happy with it. The boiler hasn't been this quiet or heated this well since I restarted it in 2021.

Yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thank the dead men, gas law, hydrodynamics, Mr. Holohan, the fine members of the forum and Bell & Gossett, Bell & Gossett which also makes hydraulic control valves.


Enjoy the heat.
