Trinity Ti150 problem/advice
in sept 09, we had a Ti150 (NTI) hot water boiler installed in our 2200 sq ft ranch house. it has worked flawlessly until yesterday. from what i can tell by the display error (ASC), the 24V transformer which also controls the blower fan has failed. unfortunately, i don't trust or want the installer back in my house. he originally told me we didn't need to connect the outdoor reset temp sensor, or the outside air intake. when i explained that I wanted him to do it according to the manufacturers install he agreed, but only after trying to convince me i didn't 'need it'. BS. so now, after discovering this code, i'm attempting to find a new transformer as there is no current across terminals B & D as the manual says to check. i just want to get our boiler on again (no hot water, obviously) so i will swap it out myself. i live on long island,ny, in suffolk county and would like to find a qualified tech to service this unit. where do i find this guy?? any advice where to look? i searched google but trying to find a mod/con aware tech isn't easy.

i'm happy to report i figured out the problem, and to no surprise it was installer related. the installer put the pvc intake pipe thru the wall without an elbow pointing it down. since the intake is located under a deck, i never noticed that. water kept coming when it rained, and getting into tthe intake loop, building up in the trap under the boiler. eventually, it started to interfere with intake, and the boiler would not fire up, since the intake airflow was getting restricted. after removing the water in the trap, and blowing out the tubes connecting the air control switch, the boiler fired right up and is running fine. at least i was able to fix it myself, and not have to spend money for a part or repair that was uneeded.

I had a similar problem with a Ti boiler.
This problem related to the intake being beside the main AC trunk in an enclosed bulk head. Hot humid air was able to condense in the intake line and drain back to the intake.
Not sure why NTI design the intake to loop down and form a trap with out any provision to drain it.
I drilled a small hole in the lowest part, and that will drain any water out.

I REALLY dont think your gonna pull any significant inside air into the unit, and so what if you did bring a bit in...
But hey, go ahead and plug it. If its your house then you will know if you need to drain it, as long as your home and not on a vacation in the middle of winter.
A small hole left open is self draining, and I doubt there would be significant seepage. Better yet cut in a tee for use with a barbed fitting and run a trapped drain connection. Should really be there anyways IMHO.
