This might be a long day. This boiler is several hours away - but with a little luck - will be purring later this evening. BEA 58/Hansa combination. I am really interested in the flue gas analysis and a smoke test BEFORE I start the tuneup. I don't ever recall a plugged boiler quite like this one.

that no Looky Good.

WoW ! I thought only American made boilers did that. (hehehe)

rich pickering

American made

The oil was probably American.

Unless it was some of our fine Canadian crude.

Goes to show ya....

Ignorance and stupidity is NOT an American franchise...

I too would be interested in seeing pre and post combustion analysis numbers.

Good catch. Sorry you have to be the soot monkey for the day.

I'll bet

that the boiler/burner was never set up properly to begin with nor was it serviced or tuned subsequently.

Fascinating...

At first, I thought I was looking into the chamber and wondered where the flue was. Then I looked a bit more closely and realized that the refractory cup was still in place! Yikes....

Given how plugged up it is, I'm surprised this unit fired at all... how many years since it was last serviced properly, if ever?

Please do

Try and get a before and after reading on that poor thing. After you get it cleaned out, remind the owner of all the money he's blown up the chimney since the last time it was looked at. Maybe he'll invest in annual maintenance...........ya think?

But...

These things come "ready to rock" right from the factory....why would I need to do a combustion analysis?

Sorry you gotta be the vac jockey on this one, but at least it's in the hands of a real pro now. Like everyone else, I'd too like to see the numbers. Chris

Constantin

Ha

They come ready to rock, assuming that you have the same flue system at home as they do at the factory. Not likely, I suppose. :-P

IMHMHO, combustion analyzers are mandatory no matter what kind of combustion appliance is being installed. But you knew that already.

The numbers ....

by the time I arrived on site the HO had brushed, vacuumed and polished the comb chamber to a like new cleanliness. Truly clean. Pre-service numbers (cold boiler): Smoke - off the scale in three pulls - fourth pull plugged the filter paper, excess air - 12 %, CO2 13.8, CO - climbing to the moon - but I unplugged my analyser at 4000 ppm. Stack temp of 190 deg F. This is an HO installation - with the best advice available via telephone (not me). Chimney is OK as is comb air. Burner was "setup" by supplier at sea level - commented that the 2500 foot change in elevation was "no big deal". And don't look for the Vitola/Hansa combination in any big V price book - it just ain't there. Although we have many of these setups in BC - it was never fully sanctioned by V. Back to the system - this one has everything! Radiant, air handlers, indirects, pool htex, etc, a heat load was easy. Final numbers: 0-T smoke (had to circle the test on the strip to see it), CO2 - 10.9%, EA - 29%, Oh two, 4.9%, CO 8, stack temp 340 deg F, (after drilling a few holes), OF draft 0.01, breech draft -.02, pump pres 160 with a 1.65x45S Steinen, 0 vacuum. Final analysis taken at a boiler temp of 170 deg F. All the above comments are correct - this had never seen a tech since it was put in several years ago (let me rephrase that - this install had never seen a tech with all the gear!) - the HO was getting darn good at cleaning the boiler. Eventhough he has a thriving practise (MD) - he could pick up some side money as a sweep. Course he just laughed at me when I suggested that. Hansa burners are a darn good fit for the Vitola Biferral - wonderfully adjustable for firing rate and application. I can claim no magic here - just attention to detail with these very nice euro products. BTW - I too invested in the new Sprinter last week - 74 liters to go 755 KM (round trip on this service call) Very impressive vehicle - perfectly suited to our business.

forgot EF -

before - 89.9% after 86%

[Deleted User]

That's the one paramter...

I recommend people ignore... (Jim Davis too)

1,000 different ways to get to that number. Which one is correct?

Good job Glen!

I hope the good doctor realizes how close to death he really was... All it would have taken would have been some back draft from his GenAir grille, and VIOLA, no more good doctor, or a vegatablized one.

CO analysis is SERIOUS business. If you don't test, then you don't know, and someone could die for it...

thanks Mark -

While HO's love hearing really big numbers WRT EF - I consider it secondary to excellent combustion values. And I will sacrafice a little c oh 2 infavour of longevity and cleanliness. I didn't tune this way forever - I now have a better understanding of the relationship of all the numbers rather than concentrating on one or the other. I do the same tuning commercial gas riello's or Weishapt burners - and rarely hear from my clients that combustion has been poor. And I agree - test each and every burner every time.
