should smoke come out of the secondary air shutter?

Steamhead (in transit)

The boiler has plugged with soot and the "hot air" is exhaust gases being discharged into the basement. Get it fixed right away and don't run the boiler until it's fixed.

If that AFG doesn't have a CleanCut fuel unit and R7184U primary, have it upgraded to include these items. Set the "motor-off delay" to a minimum of 30 seconds. This will clean up the burner's startup and shutdown periods and the boiler will be much less likely to plug up again. We did this to an AFG on a 2-68 a couple years ago and it has run flawlessly ever since. Every 68 series boiler we encounter gets this upgrade.

should smoke come out of the secondary air shutter?

On my Weil Mclain p268-w boiler with beckett AFG burner there is black soot around the secondary air shutter and hot air can be felt blowing out of it while running. IS this normal?

When was it last cleaned & tuned? Sounds like either the boiler is partially plugged/sooted up or the chimney is partially blocked. Get someone out to check clean and tune it and check the chimney ASAP!

If needed see: Resources, Find a Professional, above.

No, it's not plugged with soot as a reinspection just confirmed that the cleaning from last month is still good.

Could improper air adjustments be causing this? The smoke is especially present on a cold start up.

Another couple thoughts on this: is that there is a very long run of chimney, a couple bends then like 24' to the roof.

I recently replaced a nozzle and may not have seated the gun fully foward? if that's possible.

Not forgiving

This boiler is NOT FORGIVING, it has to be cleaned thoroughly and SET UP WITH TEST EQUIPMENT. They are so small it takes very little to throw them off.

The 2 kids that showed up for an emergency call last year adjusted the furnace by sight without a tool. The flame reaches the back of the firebox and licks up over the top which seems excessive, but I'm no expert and I don't know of any good furnace people in my area.

Dave_4

would sealing the secondary shutter harm the operation of the furnace?

oh O!

that is not sounding too good.

few questions ,

do you have dedicated outside makeup air for the boiler?

any new dryers, kitchen, bathroom remodeling ?

if you are unsure of the make up air, open the nearest window or door to the great outdoors, with a clear path to the boiler, turn up a t stat go check..same thing happening?

Do not allow anyone to work on that burner

without a digital combustion analyzer. Period. Setting burners by eye never worked well, and with current analyzer technology there's no excuse for eyeballing anymore.

Also, are you sure the boiler was cleaned PROPERLY?

never ceases to amaze me

let's say a tune up is 100 bucks depending on area pay now or pay later a pro see these everyday and should know how it operates and yes at times rookies make mistakes thats how we or they learn but if a homeowner has a problem after a service call or tune up call back right away and if it is more than a greenie can handle a good co. will send out a more experienced tech at no xtra charge most important if u mess with it tell the tech so they can fix it right and yes shoving the drawer assembly the whole way in may be a problem ther is a gauge to set the proper place call in a pro and have it adjusted to manufacturer spec's royboy

Second that.....

opinion. The only way to beat it is to....know it. A professional tech takes the time, most likely his own time, to learn so he/she can feel confident about his/her ability to make the proper repair diagnosis/replacement.

It seems some individuals visit this web site to perform what amounts to "Knowledge Shoplifting".

Guess what if you want my knowledge, you are going to have to purchase it. Pick up the phone and make the call for service.

We both go to the same food store to feed our families; have not seen any freebies there lately.....

Weezbo

yes , instead of coming back out the air shutter,

it would likely take to melting the transformer...
