I have recently been introduced to Steam Heating and had a need to replace a leaky boiler. Heating Help has proven a treasure trove of information and has enabled me to install the replacement boiler and re-work some piping to Main Line Vents where there were none.
Could a few of you "Pros" weigh in on the antler vent installed at the end of line?
The Main piping is 1 1/2 in dropping into a 3/4 in dry condensate return.
The 2 vents installed are Gorton #1.
You guys are the best and your professional opinions greatly appreciated.

Looks OK to me...Br. Jamie, osb

Just to clarify my question, I could not install the vent antler vertical due to piping to a radiator and joist interference, so I installed the riser to the vents at a 45 angle.
Thanks again0 -

The 1 1/2" main is 14 ft and previous to that a 2" main of 23 ft0

Hard to tell from picture. I would think that the vent piping and the piping downstream, would fill with water. Which way is the main pitched?0

OK- the 2 Gorton #1 vents should be sufficient, as is the 45° angle. I've done the same thing.
But the vents should be piped before the return connection. Your current setup has that capped "dead end" which will fill with water and possibly bang. The reducing coupling between the existing vent tee and the dry return connection creates another water pocket.
Get a 1-1/2x3/4" tee (1-1/2" straight-through, 3/4" coming out the side) for your vents, then a 1-1/2" shoulder nipple and a 1-1/2"x3/4" reducing 90° elbow pointing down for the return line. You may need some 3/4" fittings to tie the return in also. That should do it!All Steamed Up, Inc.
