Hey Chris. Not a problem I guess when it comes from the company. I just completed a job almost identical to this string. My tees were only 22" deep but were 60-0 in lgth. I went to Tyco literature and it pretty much disagrees with what they told you on the phone. I followed their submittal data.......TYCO-Tech Data-Extended Coverage-TFP220 (EC14's)-pg 4-Concrete tees item #1. Tell me I'm wrong because I would love to use EC hds but I interpret this spec for what it says. Thanks Geoff

A 58' long tee's in my case with only a 22" stem would not require baffles with the use of EC14's. Ken was quick and certain like he fielded this question before.

Over 32 ft in lgth, with EC heads, you will need baffles. Says so in the specs! It does not say this for 5.6 or 8.0 std or QR sprks. I believe the 32-0 lgth is the deciding factor for EC heads.

FYI if you can keep a 22" deflector you do not need to look at the special application stuff. So depending on stem oc dimensions you might get to 22-24" deep before you have to go with baffles.

EC heads in concrete tee construction. If you look at regular QR sprks and not EC, it does not appear that you need baffles.

Great, 1-6" down 22" max etc. But then there is a special application for concrete tee's that gives you up to 31" down if you meet all the other criteria. Think baffles 32' o.c. So the question is if I can hold the 22" and meet the normal obstruction rules can I use these under tee's like normal obstructed construction or do I still have to use the special application requirements? (Tyco is closed for the day) I think the answer is yes. I think the special application is only for an exception to the "exception" that allows 22" down compared to the normal 1-12". But I can read it either way. In this case I'd like to stick with 22" because I can with the particulars on the job. So I have a biased opinion. And I'm only bidding so not in a pinch (yet).
