Hello, Do you go 120vac directly to transform? Or is there a separate transformer away from boiler?
@@whatmeworrynotoday I have the same system that's in the video. If you have the same or similar system, then you should only have one transformer. You hook up the wires carrying 120 volts to the primary side of the transformer. The other side of the transformer will be your 24 volts coming out.
I love your damper wiring .
Great, thanks
Thank you so very much, exactly what I needed. You the man!!!!!!
You’re welcome! You gave me something to do, bored out of my mind!
Never seen anything better
You don't seem to know what you are looking at. You just pointed out the obvious. Thanks!
You’re welcome, glad to help!
My Johnson Controls Mizer has weakened and isnt functioning anymore. I bought a Field Controls like the one you have in this video. I also have this Weil McLain boiler. Wondering how to switch the vent damper with the new one. Seems like they have the same molex.
Thanks for the video was very helpful.
Question I have am old house, one of the water heaters doesn't heat, what do you recommend??
Thank you..
Hi, would you be able to explain which spill swich shoud i buy, i have 2 wires coming out of boilers and they go to draft hood spill swich, but spill swich never came with the boiler, my boiler is similar to your weil mclain cga 3, thank you
Outstanding
Thanks for a perfect explanation
Thank you!!!
I have a used vent damper and would like to check it out before using. which 2 wires open the damper and which two close it. e.g. black and green seem to be power sources as they come from the transformer ( unless one is the ground from the transformer) and the red and yellow seem to complete a circuit - the yellow could also have power since it travels trough the thermostat HELP!!!
Great work
Thanks for the kind words 👍🏻
Wat the purpose for each wire to activate the boiler
Astonishing
Thanks for this video. Would you to make a video about how to wire a low cut-off switch ?
Do you know how to bypass the vent damper using a jumper on the Aquastat Relay outlet? Which two lines should connected? Red to Black? Assuming that the Vent Damper is faulty, a correct jumper on the Aquastat Relay should make it work, right?
So interesting
Need help how can i bypass it so i can remove the vent damper mechanism which wire color should be cross?
exactly.
Keep in mind different makes of boilers the colors for wires will change.
Yes, definitely a valid point. Thanks
We have the same boiler my Spill Switch w/ Manual Reset button just went, I see you have the same one
That's an easy fix, order the part and get it done
Hi zimsjeep, i have some recessed downlight for you to do the video,how do i contact you?
my boiler is not not firing up I check everything but my thermostat saying no power what can i do.
Hi there, How do you adjust the boiler pressure or turn down the heat?
Thank you
Hi Zim. do you know somebody in brooklyn ny how to wire a boiler system
Hi Monica, I’m out east in Suffolk. I don’t know many guys that work in the city. You can take a look at Mikey Pipes (RUclipsr). I believe he does work in Queens, maybe he can make his way to Brooklyn. He does nice work.
I’m sorry but you’re installing a damper on the exhaust or chimney pipe. You do not lose heat from your boiler up the chimney. The combustion chamber will cool regardless of a damper or not. If someone should try this install and does it wrong, they have the possibility of filling their home with carbon monoxide…the silent killer.
Dennis Johnson, I went to school with someone by that name. NY? Anyway you can loose up to 70% residual heat up the flue when the boiler reaches temp. The damper helps for the first 3-5 min, that’s it. No concern of CO with this install because if it’s wired wrong, the boiler will not fire. 🤘🤘. Also, CO detectors are a must!
People have asked how to bypass the damper to fire the gas valve, and I noticed that you have not replied to either of the people with that question, is that something that you or anyone else can answer?
I tell customers...I don't use vent dampers...Been doing boiler for over 30 years...your not really saving much when you pay a plumber to replace it the second time around... 1st service call is $200 ...depending on the time and day... He notice the vent damper is broken..... How do you know when its defective... easy...you twist it and it comes on... Now if you want to replace the vent damper...that will cost you a 2nd service call $200 not including parts and labor.. ... $400 or more ........depending on the size... wow....by the time you are finish....possible over $1000 ...WTF .... What if you don't replace the vent damper.....well....then you pay a little more on energy...possible $20 ..Only use boiler in the winter time .. ..... so your good for 15 years if you don't replace it... by that time...your going to need a new boiler... Easy Peasey on the math... Do you see a vent damper on your water heater which uses all year round ? Your right about the vent damper...its to save energy and keep the heat in .... You know what...I only used Field Control Vent dampers... for some reason ..they are the only one stock where I purchase boiler parts ...(interesting) .. Good luck .. This is not professional advice ...This is my opinion only.
Yeah, I hear you. Thats why I do it myself…I don’t have the money to have someone come in ripping me off…and that’s no knock on the professionals. I know they need to make money too.
Can you tell me how to bypass the vent damper on an Aquastat Relay using just a copper wire? My Vent Damper has four lines: green, red, black, and white. Green line splits and goes into two holes on the Relay connector.
I followed the wiring diagram exactly as described but your wiring suggestions caused my transformer to blow! Be careful guys.
That’s really odd. Do you have the same boiler? As you can see in the vid, thats exactly how mine is connected
The only way that would happen is if you shorted the transformer by connecting terminal R directly or indirectly to terminal C without a load between them. Terminal R is 24 volts hot and terminal C is common(aka neutral or ground). NEVER connect those 2 terminals together without a load in between them.
The harness wring colors vary wildly and meaningless. What matters is the short pigtail on the damper itself.
Field Controls: [Blk -> R ; Brn -> C (Transformer)] ; Or -> Aquastat/Limit Sw ; Y -> Gas Valve
Just got quoted $600 by a HVAC company.....I laughed and asked will the boiler be able to sexually pleasure me with this new damper.......reminds me of car dealerships just raping you with bogus fees......I'll be doing my self 😂😂
Yeah this for sure is an easy one to diy. I think part of it with contractors is they really don’t want small jobs like this…but, will take them on if they can rip you off at a certain price point. Good luck with the job 👍🏻
