Weil McLain CGA6 Natural Gas Boiler Installation
Вставка
- Опубліковано 29 гру 2020
- So last week, we brought the old American Standard 199k BTU (gross) single zone boiler back to life. House was recently bought and almost done with renovations. Of course, the 40 year old boiler works so why replace it, right? Wrong! When we resurrected the boiler, we did a combustion test. Very high CO and told client consider replacing it or, not recommended, major cleaning and overhaul. Not cost effective. Limited basement staircase clearance meant a WM CGa6 instead of the typical Burnham ES26. Watch as we take out and install the replacement. Appreciate the feedback.

Why do you push why don't you pull your circulator and put it on the bottom
I can answer that. It's called pumping away. There are a lot of books to read on that subject..by: Dan Holohan
Because it's the correct way to do it.
Why not add valve above pump for future swap . Could have set up little better but nice install better than burner king
@@PipeDoctor I get it , just found your channel and think it's pretty cool , in the same business and just breaking balls which is also part of business
Ray Moran The install manual shows the pump on the bottom....seems like the company that built the boilers should know where to put it.....
They have the top position as an alternate......I have seen pumps right on top of the boiler also which is problematic. Because if you have to pull the pump you have possible water infiltration......unless plenty of towels are available........
Watching from the U.K. nice to see how you guys do it across the pond. 👍🏻
You do have limp wrist battery pipe cutters though 😁
You guys work pretty quick! In at 8am out by 12pm. 4 hours to install a cast iron boiler! Nice!
True but there we 3 techs so it is 12 man hours A lot of contractors can not land a party that size on one job, in my State even that small amount of electrical work would require a separate trade electrician and an inspection. Most town inspectors would fail it on the lack of isolation with the pump in my area. Some may even want to see a pressure test with that small amount of gas piping. Respect the work here, but we all play by different rules.
I'm In the industrial boiler business, love your videos and still watch Steve's videos too lol. You mentioned no red tag state was just wondering how that works. I'm up here in Toronto Canada and we got all kinds of regulations to work around. Keep up the great work boys and Calvin pay attention every day cause that's what makes a good mechanic
Wow nice to see Kalvin showing initiative seems like he's finally getting it good job Mike .
Wonder if that was a steam to hot water conversion, that fitting may have been part of the old system,lwco or supply or return sensor,I love seeing weired shit like that! Gets the wheels turning! Great vid
Woww. I had to look at what year this video was uploaded when i seen the fuses 🤣. I haven't seen fuse boxes in over almost 30 years. Good video
I had that happen before with Weil McLain boilers before where my supply piping came out on an angle. Can’t remember if it was oil or gas. I liked the placement of the expansion tank. When it fails it will be a easy change out. So many times there 7 feet off the ground directly above the tankless coil piping or burner. Drop that tank and forget it your day is ruined 🤦♂️ I got a critique hard to tell from video on the size of house and how many cast iron radiators but generally I go with a number 60 but have done 30s also on smaller homes. Happy new year’s guys🍻
Great watching your videos very informative, very interesting and you are very knowledgeable , great stuff.
Nice clean professional work.
Its beautiful nice work and enjoyable conversation
A little electrical info: the transformer above the old fuse box was most likely for the clock portion of the old setback thermostat (very common back then). The existing BX cable is technically AC cable (armored cable). If in good condition and properly terminated, it is an approved grounding means. The silver wire is Tinned copper. The tin stops the sulfur in the old rubber insulation from corroding the copper wire.
Joe S Very well said! Thank-you
You definitely know your stuff
Here in Florida we call it MC for metal clad cable. Also down here the only approved means of ground happens with the MC that has A green parallel line painted on the outside of the MC and contains a bare ground wire throughout it.. The Cladding does not serve as a ground. How do you know thats tinned copper, just curious? IF it was aluminum we would have to do a remediation on it and add alumicons to the joints, here in Florida and for the insurance companies approval.
I still have a mechanical setback thermostat on my steam system. Honeywell Chronotherm. It's staying when I install the new Burnham Megasteam. Best thermostat for a steam system ever. Adjustable magnet for the bimetal so it can be calibrated in place. Mine is the art deco style with the clock on the side. Wired with 4 wire armored thermostat cable. Have the original Honeywell clock transformer powering it. Inside it has a dial with 2 hands for setting the setback times. I also have a nearly identical fuse box with a separate 0.5a fuse for the clock transformer. It's staying as well. I rewired it with modern plastic insulated MC cable.
nice job and quick too
Your going to go big time on here!!!!!! Your going to smash UA-cam like Eddie van halen did the music when first album came out in 78 ,. I have to pause because I'm crying like a baby,l am a musician,.. can't play no more,. Because he died,..well maybe I should have started like this name is veto old school italian your channel is excellent,.. And so r you, your gonna get that 1000 and many many more cosa nostra my friend I'm getting back to installing the boiler,
Nice install!
🤘🤘rock on Fella’s not too shabby... especially calvins nice and straight flue pipe cut with the grinder lol... invest in a pair of tin snips brotha
With all respects; your combustion probe is in the drath diverter. Should be between boiler and the draft diverter . your position sensor is reading combination gas mixed with make up air. Your an amazing true respects to you and your crew.
@@PipeDoctor Sweet. Wishing you and your family a most happy new year and best of health. Thanks for passing it forward to all techs around the world.
Great job. I am a little disappointed that you didn't try to replace that old BX. At the very leased I would have cut it back a foot or so to get to fresher stuff. When I was stuck with a junction box full of cloth coated wire I would spay truck bed liner on the wires and go the lunch before working on them.
Great video. If Kelvin is working over a year for you and you are still telling him how to measure a piece of tubing to tie the cold water in, it’s not Kelvin it’s the teacher. If you are constantly clipping their wings they will never fly. Food for thought.
Oh well.
Top install Mikey
Men you are the best on UA-cam
Love the old Western Electric splice at the fuse panel!
Solder and friction tape! Yep
@@PipeDoctor That's called Western Union, easy mixup though, there were two "western" companies in telecom back in the day. Western Union was the big telegraph company. Western Electric was the manufacturer and supply house for the Bell companies such as New York Telephone (now part of Verizon) in your area.
Thanks for the content. Awesome. Just why no air scope ? Curious .
Tin snips seem like they would be a welcome addition to the tool bag over cutting pipe with the grinder.
Kelvin good job
Nice clean install , if that's what your into doing I guess.
That crooked ass supply pipe would bug the shit out of me along with that stovepipe cut. I’m OCD about symmetry! Overall nice install Mikey Pipes and Happy New Year to you and your family.
We used to put swing joints right off the top because of so many bad taps.
Had the same problem with fittings as well over the years.
"Im Not Taking A Dump In This Guys House" hahahahaha. Im the same way. Ill go to a fast food place or supply house before I use a customers bathroom. Fellow Hvac tech/owner from Nyc
Had a guy workin for me who plugged up the toilet after taking a dump. So, besides stinking up their house he had a BIG mess to clean!!! Idiots!
Kelvin Swiss cheesed that vent pipe lol. No biggie lol. Back in my apprentice days, my journeyman would have thrown that vent pipe at me from atop the ten foot ladder he was standing on waiting for me to cut the pipe.lol I miss those days, builds character. Nowadays it seems you have to be sensitive to the young generation. Great video keep up the great work!
Thank you for showing how to hook up a switch. What age do you think is too old to learn a trade? Thank you have a Happy New Year!
Mike pipe u are the best
I love the big blue box idea. Did you remove both boilers.
Thank you for changing that hose has been hard to watch. About the feed line I’ll just say buy kelvin a torch.
When you mix and match with copper and iron and plastic pipes do you make sure there is a continuation of the electrical earth bonding?. Or is it not an issue?.
Wondering if you used the proper wirenuts to connect the aluminum wire to the new copper wire?
Should the l.w.c.o be tapped in lower? On the return side? I usually see a manual reset aqua stat where the doc has his l.w.c.o. any clarification would be appreciated
What happen to the firomatic switch and air scoop.
I like your videos. I'm a gas tech in Maine and I almost exclusively install lochinvar noble boilers. Any opinions on that line? Keep up the good work. Thanks
Does the Milwaukee copper cutter also deburr the pipe?
some one probably mentioned could that wire be for the emergency shut off upstairs?
I still have a functional 66 yr old forced air gas furnace by Morrison Steel and a yo yo thermostat, and it keeps on going. Keep it or kick it to the curb?
Hi, how do you gauge whether to include an air scoop or spirovent in the system or not?
Really enjoyed the video. Not a big fan of the flue dampers if it hangs up and shuts the boiler down if gone during harsh weather;
I personally would but a piece of cardboard or something to protect the top of boiler while installing. Now the jacket is gonna be all beat up. I can see that you guys are confident but it’s the little things
Something I haven't seen on youtube but was my late father's idea. If you want to super flush a radiator . Change the bleeder to 1/4 or 1/8 ball valve with a flex supply line. Close the return to the boiler and the radiator . Increase the pressure to the prv and open your new bleeder valve and see 50 years of muck come out of the radiators. I've been meaning to post a video. The radiator gets so toasty
Hi Pipey Mikeys 😁. What was the square footage of the house and what kind of heating loads radiatorsor radiant?? Thanks
@@PipeDoctor Just a year ago🤨😓.
why didnt you use sheet metsl snips, for venting ?
They make this tool called snipes for sheet metal instead of a grinder but other then that beautiful install
*snips
Fuses in Southern NH so common the Haji marts (711's)carry them lol
What brand automatic "Flood valve " is that ?
I never saw a big blue box until this video, are you going to remove the old sections?
Why iron pipe instead of copper for the supply and return?
Do you apply for permits on your boiler installs?
when i installed mine i hooked the outlet before the switch. reason why is this --- i can shut the power off to the unit for servicing but still have power for pump, vacuum, or any other power tools i may need without having extension cords all over to trip on.
How did you wire that thing? I'm looking to get better with wiring boilers and understanding what piece does what and why as I don't do a lot of them.
@@PipeDoctor you da best!
Did you guys remove the old old boiler
that's a nice PRV. What brand and model is that?
What's the difference between the series 2&3
To answer your question about that odd bit sticking out at 7:16 . I believe that is a Pete's plug with an old temperature probe inside sticking out.
What happen to the air scoop
0:42 man the house still has a coal bin???
I'm surprised the owner didn't ask you to remove the monster in the blue box too.
With systems with large water capacity it is recommended to use the next size up expansion tank.
How old was that old boiler under the blue box? Hundred years old?
Great job! For your edification: you are using MC (metal clad) cable and not AC (armored clad), also known as BX by an old trade name. MC is distinguished by its green equipment ground, which AC doesn't have. The steel armor of the AC cable functions as the equipment ground, while the (typically) aluminium cladding of the MC is not considered an equipment ground. It's likely that you were using the MC lite variety in this video, which definitely has an aluminum cladding. Importantly, set screw connectors are not to be used on this type of cable, due to it's thin and fragile nature. Instead, use snap-in or combo connectors with MC.
@@PipeDoctor Set-screw connectors for steel clad AC (AKA BX) and either snap-in, combo, or saddle connectors for MC. These won't damage the armor. Love your work, BTW. Regards, from a competent DIY guy.
Yes I agree ten fold. Great comment. BTW I love the snap in connectors.
Tip Next install- Use Siri hands free to do your math to add and subtract when determining length to cut new pipe.
Still like "Right hand thumb rule" for determining rotation direction for tightening and loosening.
Maybe you can get an Apple sponsorship. Showing how the working man can use Iphone Siri technology in your job. Like the job banter like in Clint Eastwood movie El Torino barber shop scene! Keep them coming.
Bx. That's very NYC of you. Wonder if they actually make that cable anymore. I use a lot of MC.
The old style BX is known as AC, you can still get it, even the (sorry Mikey Pipes, I know you don't like this place) Home Depot in my area carries it and I'm not in an area where it is used in homes that much.
@@jrmcferren I thought AC was just the armored flex, without wire. Interesting that you can still get it. I haven't seen it for at least 10-15 years in the stores.
Did you ask the homeowner if he wanted the old boiler sections removed for extra $$$? Also, is the BX an acceptable ground in today’s code? Just wondering if you were required to run new Romex from the service panel to eliminate the old 2 conductor wiring...nice job...first time seeing gate valve on natural gas!
It looked like he was using type MC, not Bx. Separate full size grounding conductor.
Fuses were marked clock for clock thermostat. I would guess Romex is for switch on stairs.
Very good installation, but the only thing missing was showing us the electric installation of the boiler
Was that supply wiring actually aluminum or was it just tinned copper? If aluminum remember to use the purple AL/CU transition wire nuts to a copper pigtail. Also needs anti-oxidant compound (noalox) if wire nuts are not already pre-filled with the "goop". Do not wire aluminum wires directly into switch or receptical unless it is specifically rated for aluminum wire. Needs a transition to copper with pigtail first in most cases.
Fused disconnects are still common on heating equipment. Did you ever hear of a SSU or SSY switch ?
@@PipeDoctor It a cover for a 2 inch or 4 inch electrical box with a shut off switch and a screw in fuse. You put in what ever size fuse you want to protect the equipment.
Did you ever see an old EFM coal stoker pushed to the corner in a basement. That might be a Pennsylvania thing, as they were made in Emmaus PA.
Did they just discontinue the series 2( Goldie ) ???????? Can’t find them anymore???? I’m thinking so .....is the series 3 better?
@@PipeDoctor that stinks I hope the series 3 is as easy to work on and is reliable as the gold series 2, I was gonna buy it last spring and decided not to because of covid uncertainties and now I go to buy it and I can’t even find them 🙄🤷
Aluminum or Tin coated copper?If it's aluminum,you have to do a fix with the ideal purple nuts,or do the crimps,the solid copper pigtails are ripe for the work to be completed!
Dont you have Remote heating i the city ? the boilers are so 1970, we just heat exchange , we have 90 degrades C in and I live in a house small town, where all are using head from the Town 20Km away, It easy and cheap, and I live in Denmark, But I like you videos and and you are good and nice to people I like that
We’re you geg this 3/4 hoses ?? Do you think they make it better to purge baseboards
Moreland Hose Hempstead or Oakdale NY will made any size hose, call first just to make sure they have what you need
Steam heat with cast iron radiators is the best heating system IMO...
IMO
Steam heat should not be allowed in residential only commercial heating (neglect) or there should be more redundancy like commercial with the 2 required pressure& low water safety's

Stay safe always wear your safety glasses!
Love the install just wishing you would Deburr the inside of your pipe so that no "HYDRAULIC JUMP" would be caused. Hey maybe you did off camera who am I to say.
@@PipeDoctor I knew it! Keep killing it out west. I’m going to keep it up on the east end.
Mike, why did you feed cold water into the supply instead of going into the return?
@@PipeDoctor I did check the manual, but according to section 3B for single zone system on figure 10;
Connect tank to 1⁄2” NPT tapping located BEHING SUPPLY OUTLET, using 1⁄2” NPT piping. Pitch any horizontal piping up towards tank 1 inch per 5 feet of piping.
I'm understanding that it should be connected where you have the automatic vent NOT IN THE SUPPLY INSTEAD.
@@scobar0076 the tank they are referring to is a non bladder tank. We don’t use those any more , so the air vent goes there. Weil boilers have an integrated air scoop in the section. No air scoop is ever necessary on their cast iron boilers.
Mikey, no ball valve on the top of the pump?
I know how that goes. Love your channel Brother. I've been in business for 25 years (hvac) so I love watching someone with the same passion for their trade. Keep up the good work.
Should clean all cut copper for press learned hard way cut rubber on 2" in a pain in the ass spot no room. I also mark edge with sharpie so if fitting moves you notice especially on bigger pipe. Do you use any offsets they make the impossible possible on tight ass spots for crimping.
U guys blaze a joint on the way to the job??! 😂
I thought those series 3 were supposed to have a built in Lwco
Tell kelvin wear some knee pads or a matt his knees are going to be screwed up
Great video but snips would be better then using a grinder for the flue pipe
The low voltage transformer was connected to the fuse on the right, labeled "clock". Hmmm
You replaced the atmospheric boiler with another atmospheric one?
Yes with that much water column.
If you have a good chimney it’s always better for the customer to use a cast iron boiler. The customer will use more gas but the overall costs and longevity will be better with an “old fashioned “ boiler.
It looks like they replaced it but it should be a filter screen
And then the sectional rubber o-rings go bad 10 years later... 😞
I don’t think that wire was aluminum.... it is usually tinned copper.
good video thank you, but you not
show the water cut off electric wired install
Why don’t you just get another blue box ?
The floor was off not the tapping.I see Dan hulahan in you lol but never had a problems pumping in JS .
Safety glasses vs down time visit wills eye than laugh at them,you only get 2
just say'n be safe
Wear your safety glasses

Kelvin is the result of parents and schools taking away anything even remotely dangerous from their hands and substituting video game controllers and constant sanitization.
Mono supply and return and return should be 12 inch apart to work properly those look close
Monoflow tees should be spaced the same spread as the emitters. Example: 5 foot baseboard, tees 5 ft apart.
Looking for new & simple direct vent (no chimney) gas boiler (80% efficiency is fine) that has best shot to last 20 to 25 years and is low maintenance - zero bells and whistles. My focus is not efficiency. Priority = low maintenance and longevity. Currently running 1991 Slant Fin V90 - 80% Direct Vent - baseboard forced hot water - has been excellent, but time to change out. Thoughts, guys/gals? TY!
You are asking an impossible question to answer. "Direct ven" no chimney, needs a draft motor. They don't last 20-25 years. Imagine anything lasting that long???!!!!
@@PipeDoctor TY for the prompt reply. Yes, it would be a Power Vent (sorry I said Direct Vent). My current Slant/Fin V90 (Power Vent) is still going strong - purchased 1991. 32 years. Crazy. Ahhhh, the good ole' days. :)
Do you prefer WM over Burnham? If so why?
@@PipeDoctor So what do you think about Burnham compared to WM?
@@PipeDoctor Agreed and the client needs heat otherwise you would have exchanged it for sure. Kelvin should practice cutting on a straight line too.I think you should complain to WM to get a credit on the next purchase. Tell them the Cisco Kid doesn’t appreciate them making Mikey Pipes look bad he doesn’t roll like that ever!
do you think you're ever gonna get sick from all the asbestos you work around
What do you guys do with the old boilers you haul away? Do you get money for the scrap metal?
Anyone else think this guy sounds like bruce willis
Holy shit it can never be unheard mike is Bruce Willis voice lol
Some of them old boilers had thermometers on them
Glasses or face shield. Boy was closing his eyes while cutting!
Kelvin is getting better every day. All he needs is more self confidence and less comments from Mikey Pipes.
