    That fitting looks like it has been installed using "grip" as a sealant, which very effectively dang near welds the fitting on.

    What I would do is put the pipe wrench on the pipe with the pipe on the left side and the handle straight out, and you standing so your left side is next to the wall, and then put at least an 18" crescent style wrench on the fitting with its handle a few inches in front of the pipe wrench. Then put the pipe wrench against your chest and lean on it to hold it in place. then grab the crescent wrench and pull toward you until either the fitting comes loose, or you chest hurts too much. Expect some chest bruising if it is too tight. You can also put some padding on your chest before you start. If that doesn't work, a lot of times you can go the other way until it moves, and then try removing it with the wrenches set up like before.

    How to remove old fittings

    was the title and looking at all the responses from @azward I have a feeling that he is related to a guy that worked for me that didn't have the mechanical aptitude but was really book smart. Understood what was needed but could not apply the concept manually.

    This is a how he might remove old fittings from my garage.

    And he would be correct in his mind, but wouldn't have accomplished the task I needed him to do

    After you make that expensive repair and you still have the same problem, What will you check next?

    @EdTheHeaterMan just saw your post. I haven't got a chance to touch that fitting yet, being busy deflecting balls of life. maybe it's better push it back until the gas inspection is done. I never thought these cast iron fittings are so tight, so it is challenging. The good thing is you guys are here to light the way.

    you could put a flare cap on it to pass the inspection.

    To eliminate the entire system would require finding a location for the thermostat wires on the intelligent boiler control, because the boiler thermostat connection is located on the IQ panel. That is why it took me about 2 hours to remove the IQ panel. I needed to determine where all the unused wires needed to go, including the thermostat wires.

    It is doable — I just cannot remember the exact details because it was so long ago. I believe the yellow wires connected to the 9-pin P5 connector, terminals 9 and 7, might have been the thermostat wires, but it has been long enough that I cannot be certain.

    That will probably require some trial-and-error testing to determine whether the yellow wires are 24 VAC power from the transformer or the actual thermostat wires. A meter may help you determine that. Try connecting the yellow wires together with a fuse. If the fuse blows, then it is 24 VAC power for the IQ panel. If the system starts, then it is the thermostat circuit.

    After that is determined, you can proceed with removing the IQ panel because all the remaining wires will be EnviraCOM system wiring that you are not using.


    This is the second time this has happened to me this week. Apparently, I need more spinach salad and salmon for memory enhancement—or at least a bigger supply of sticky notes! 😄

    Is it just me or does that look cross threaded?

    @EdTheHeaterMan this is the gas pipe for a dryer, not a boiler. you are probably posting to another thread?

    Cross reference to dope & tape in this conference. Tapered thread connections can be problematic. There are alternatives.
