Small baseboard heater no heat

Ianlovestish_05

I have a new install boiler weil mclain cga-4 with taco 007e pump on single loop 1” with 3/4” baseboards. The bathroom baseboard won’t heat up I have purged it several times at the baseboard plenty of pressure and no air coming out. I’m stumped I can provide pictures any help appreciated

How is it piped? Monoflo loop?

Are your other baseboards heating? If it is a series loop they will all heat or not heat. If it's a monoflo loop it's a different story

I’m pretty sure it’s mono flow it has a 1” loop with 3/8” branches off of it all other baseboards work fine

The classic air bubble, look for a pipe pitched the wrong way. Worse case you’ll need to cut in a purge

It's definitely an air pocket. If you have a coin vent on the baseboard you can easily get the air out.
I've heard a few drops of dawn dish detergent added to the boiler will help with air removal.

I’ll try bleeding it again I have left it flow out at least 2 min before hope the installer put the correct mono flow t on there

The perimeter loop and Tee's were replaced?

It wasn't just a boiler replacement? Sure, piping at the boiler was replaced but the branches were altered too?

They didn't reverse flow did they?

You might need to bleed that rad a lot longer than 2 minutes. It might take an hour. The long runs can be a real pain in the butt.

The branches look original too me but there is some new copper piping where I believe they added the kitchen and bathroom ones the bathroom one is on the end of the loop I’ll try blending it longer

How about some pics of the piping, including the Tees for that branch?

GW

Super, if the runout(s) or the bleeder is pitched incorrectly, you can bleed till you’re red in the face- ain’t gonna happen. Sometimes one can get lucky by man handling the upside down piping and get the bubble to move

I’m back again I got the baseboard to get hot but it did not last I can hear air in the lines I don’t have a purge station just a drain I’ll post pics this time

As pics show there is no purge station and I can get the bathroom baseboard hot buy putting a hose one the drain and opening the fill valve but it won’t last

Any pictures of the old boiler and piping at it?

That gas flex line is not allowed to enter the cabinet like that.

Hmm it passed city inspection with that gas line if it’s not code I’ll change it

Ianlovestish_05

The old plumbing it where it branches off the loop is new this is what the home inspection came with

GW

Wow- code official passed that- wow 

Ianlovestish_05

Yes the did pass I was there with them I’ll change it immediately

Ianlovestish_05

This is the baseboard I’m having trouble with it gurgles when its working and when it goes silent it stops
