Blue Flame Buderus Install (Ray L)

GW Member Posts: 4,678
what is the static pressure you mentioned?

I thought these needed to be direct vented?

Is Buderus reuiring the "trained" techs to actually own the tools required? In my area, I'd guess (i really don't know, but please correct me if you believe my assumptions are lame) 1 out of 10, or less, carry an electronic combustion analyzer.

Thanks, Gary

    Finished up this install last night. The G125/34 replaced the old beastly Utica firing at 210,000 out, which for this home was 50% oversized! Other contractors said that the unit was not big enough and they would need to put in bigger!

    This was actually a very easy customer to sell to. The family is very enviromentally concious, and understand the features and benifits of RFH and this particular boiler.

    Dan and I lashed up the boiler and piping panel about 10' away from the old unit so that while we worked they still had heat. We connected to the existing 7 high temp zones using the new Viega S.S manifold and 3/4 pex whips. The superstore is only 3 years old, so we are leaving that for now. We are also installing climate panels on the 1st and 2nd floors, I am controlling the bamboo surfaces via the logomatic, mix station, and zone valves. Tile floors are zoned with the Taco I-Series mixing valve. I piped the boiler p/s because eventually the 3rd floor baseboard and supplemental exisitng baseboard on the radiant zones is going to be removed for 160* max panel rads, so all zones will be low temp.

    I still need to return when the 5" all fuel comes in for the flue, cap the future pex zones, and label everything with a labeler. I would like to also re-wire the high voltage to the pumps too. Hired a sparky to do it and workmanship was definely not his forte.

    As far as the combustion numbers, I don't have the ticket in front of me, but if memory serves me I believe my co2 was 13.8, CO 8ppm, 3 1/2"W.C static, 345psi pump pressure, 288 gross stack temp, 89.4% efficiency!

  • Pics?

    edit- there they are! BIG difference from what was there!

    Whose burner does Buderus use on the blue-flame unit?

    thats soo 90 degree :)

    i thought wow! he has the draft damper in a wierd formation.

    then i thought Wow! its bolted to the wall! they really are huge pictures :)

    is that the 3000 controller?

    woah those are nice numbers.

    that is pretty high atomization pressure...i wonder how the pump would hold up to really cold oil....

    The Burner is made by buderus, it is incredibly easy to service, the only trick is having the repair kit because it takes special nozzles, electrodes and burner gasket.

    Weezbo, the boiler features a nozzle-line heater to warm the oil, so the high pump pressures are not an issue. This really is an amazing piece of equipment. You'd think you where looking at a natural gas fire not a oil fire!

    Blue flame.

    I'm sure the Buderus is quality, but when I hear Blue Flame, I flash back to Blueray. I wake up in a cold sweat from the nightmares.

    Looks good Ray, and those numbers are unreal!! 345psi pump..Holy Cow!

    Is it quiet?

    Can we get them now?

    Ray I was told by my local Buderus rep. that we couldn't get get the Blue Flame over here because the Germans say that our oil isn't clean enough. Are they going to start selling them now, or is this something only you were able to get? I have been wanting to try them for a couple years now.

    Jet Fuel

    Will this thing burn jet fuel? Its much cheaper than heating oil. :-) If you buy 100,000 gallons for July delivery on NYMEX anyways. What type of fuel does it need and can you get it anywhere?

    Ken , i hear what you are saying...

  • Weezbo
    Weezbo Member Posts: 6,232

    is there some special tool set for the burner ? like how did you go about bumping the pressure that high>?

    ken has a Sound point in that Bang is not good on high pressure does it have a "Glow shield that keeps the "Flame" contained? i would like to see one of these burners,into peeling the cover off the front ?is it tight to the boiler or does it have a long draw ?

    this Buderus...

    is certified to burn Bioheat...therefore much cleaner. You have to be trained @ buderus before they will sell it to you.

    Buderus G125

    Just had the certified training last week. Before anyone makes any negetive comments about high pump pressures or blue flames, definitely contact your local Buderus Rep and get up to New Hampshire to get certified. This is incredible technology. You simply cannot make any mistakes with this burner, all controls are molex connected with a different molex connector for each item. Do yourself a favor and get certified and see what all the fuss is about. Please do this before commenting this is not a Blue Ray burner.

    You hired an electrician, he saw the work you did and ran bx like that? What a shame I guess you're right when you said no workmanship. Maybe you should show your next electrician some pics of your work.

    Oil quality?

    I know of several of these installed as test pieces. They use, w/o problems 1500+ ppm sulfur #2. Know of one in operation for a year on a direct vent. No problems, even w/o the required Tiger Loop. Which has now been added. Set up parameters are relatively simple. You just have to follow them.

    Buderus has sold this piece over yonder for some time. Even back when their #2 regularly exceeded 2,000 ppm sulfur.

    Mario said they were going to do this this year. Thought he was kidding. Glad to see Buderus is taking the chance. Hope these pieces stay in the trained family of techs.

    You own a T-drill. I am jealous.

    Glad to hear it

    Looks like it is time for some more training. I'm glad Buderus is letting these come out now and helping us over here across the pond to move forward.

    This is definetly no blue ray burner. Everyone really needs to go up to buderus and see one in action, your opinion will definetly change. As Vinnie said, this technology is second to none. Has LED self diagnostics, every connection is plug and play. The burner even has a hanger so when you service it tube side up it stays nice and rigid.

    High sulfer oil is not an issue with the boiler. You may atmospheric vent the boiler, with a liner. I definetly agree with you gary, not many techs in our area have the proper training/equipment to service these boilers. Our company does service and installs so we will do this one in house. Buderus offers a service kit for all common repair parts/ tools for this burner. For set up I had a 400# guage, positive/negative water tube manometer, analizer, wish I had the NoX feature on my TSI though. Woehler offers one that seems slick.

    Mike Dunn, I don't own a T-Drill, yet. Those are pre made copper EZ headers. REally save on time.

    I really do regret hiring an electrician. This particular job involved moving the romex whip to the burner firomatic, and every town in Mass seems to have a different opinion on if an oil burner man can do the wiring when zones are being added/firomatic moving, so that is why I used him, he was also already on the job doing wiring for an addition for them. I did all the low voltage snaked behind the boiler wall, and bent all the conduit for the low and high voltage. Every time I tried to suggest something to make things neater he just ignored it. It was Friday afternoon and I just wanted to get them heat! I think I will probably say something to his boss though, because it really is atrocious!

    What is the cost above and beyond a standard G115? 10-15%? Just curious if it is worth the the money for minimal fuel savings or it's just a green thing? I know this is probably the next step towards the introduction of the condensing version but is it really worth it or is it just the shiny new bike? I'm already getting 87+ combustion efficiency out of many three pass units.

    Not bashing, just asking....

    In Dan or Siggy's books, maybe both, in a primary loop,they say there should be 8 pipe diameters before a secondary loop supply and 4 pipe diameters after the secondary loop return. Does this not apply in all cases? What, if any are the consequences if this rule is not followed? I see some installs where this is followed, some where it is not, just wondering..what is the importance?

    New Gas Steam Boiler - BAD SMELL - like Diesel Fumes


    I have installed a new gas fired Weil MMcLain gas fired steam boiler. This boiler system uses city water. The water smells fine. This is a single line system. There was no smell with the old boiler of the same make and model. I have flushed the boiler about 15 times or more using a silicon solution that I picked up from a major chain home improvement store. Even after flushing, the steam that comes out of every radiator stinks like exhaust from a school bus! There is now smell coming from the chimney. I do not know what else to do. I have moved out of my house because the smell is so bad. Please help.

    Sulfer is not really much of a problem with Blue Flame burners. At least not nearly as much of a problem as sulfer is with condensing boilers.

    Nice work

    I've not seen the boiler up close but when anyone tries to compare the blue ray technology to todays technology I simply look beck to the auto industry. Until you had the proper electronics to control it you could not have really good fuel injection. With the proper electronics precision is possible. I have a couple old cars, one with a weber carb and one with mechanical fuel injection. Fiddle with those for a while and you get an appreciaton for EFI. That Blue Ray was almost 30 yrs ago. The technology has to have advanced. Again, nice work!

    Nice Work Ray!

    I will be up at Buderus on March 4th for the G125BE training. I am looking forward to it. It sounds like a very nice piece of equipment. Any other Wallies going to be up at Buderus on tuesday?
