How critical is the 18 inches

Cosmo

There are ways to get around the air separators....

I tried this out on the last injection loop system I out together and I think it works well. Not very hard to figure out if you think like water, however you need a little room. As you may see from the pic, the injection loop enters the secondary loop from above, and it is good pratice to keep at least a foot of straight pipe before and after the closely spaced t's. I did the initial purge, then ran the pumps without heat for about 20 minutes and the air was gone out the spirovent. WOuld have used a regular air scoop except for the clearance problem, no room for much straight pipe before the air separator inlet. I have to go back and wire up the Tekmar goodies next month!!
Cripes, I just noticed that the pics I took were way under exposed, I should have known when the flash wasn't that bright.....Will go back soon for better pics.

They cost just as much as a Spirovent and I don't think they are nearly as nice!

If your are refering to the B&G Airtrol Boiler fittings, B&G has stopped making those. This from a B&G/Bornquist Rep
at a B&G mini class I attended a couple of months ago.
