Boiler setup

I am hoping to find some answers to a few questions. Here is the scenario Weil McLain 4 section with Beckett AFG connected to a Tjernlund SS1 power venter. Here are the questions.

A) Is this Beckett AFG considered a flame retention burner or a conventional burner?

In what series do I use a Bacharac test kit ? IE; smoke test, draft, temp, and CO2.

C) How many pumps on the CO2 and how many times do I tip the Fyrite container ?

D) Which band on the AFG adjusts for CO2 ? I need to raise the CO2.

The lowest I can get the draft set is -.04, and zero smoke,
temps at 480 degrees, but the CO2 ( I pumped 18 times and tipped 3 times ) is at 4. How do I raise the co2 without messing up the other settings ? Please help...

Really, I am quite capable.....just looking for help.

Thanks

I think what

JCA is trying to say is that people who use this equipment have years of experience. They have been trained in the use of the testing equipment and do not have to ask questions like yours.

You can do harm to your home and family by not knowing what your are doing. If you want to use the euipment then get some training before you jump in. This is not like trying to tune your lawn mower !

Thanks Scott.

Think of it like a kid using a calculator. Until he/she knows WHY they're pushing the buttons, they should be sticking to the tables and learning the reasoning.This takes a LONG time. JMHO. Chris

gotta love it ---on the AFG you raise the CO level just as you would the Timken,Volcano,Robot,Carlin,Wayne,Texaco,Sears,Simplexand about the other 100's of burners out there ---you need to drop the tools-meter-and zippo ///Step Away From the unit and shut off the switch

some things are not easy to describe.....

as enthusiastic as you may be to do your own work on your boiler...really it isnt a case of having a bacharac kit or some elctronic space age gizmo with flashing didgital readouts and a data logger...really, a couple twists with a screwdriver and a tweak or two with a wrench blind folded i am fairly sure i could get you closer to the real deal...it may be that you dont belive these other guys and think they are being jerks..they arent..Your safety and your family and nearby neighbours safety is of more thier concerne day to day than any would care to admitt.dont let them down....call someone to twist the wrench and screwdriver.

If you just want help with the co2 meter OK. The fyrite fluid gets weak but if the fluid is good you have to make a great seal between the fyrite and the hose. The point is to get the fumes into the jar of fyrite and not let it out untill you take a reading. You might be in over your head because bad meters or human mistakes are more comon than you know. we have to look at everything and not just one or two things.

Everyone has to start somewhere

Seeing how less than 50% of contractors even own these tools you are already over qualified as you said. AFG is a flame retention burner. But before we test, the following mechanical things need to be checked. What is the maximum firing rate of the boiler? What nozzle came with the unit? What is your pump pressure or at least what is it supposed to be? The venter should be set up to run at least 5-8 minutes after the burner shuts down(need to check this or you will have problems). Draft is always set first by checking over the burner. This should be -.01"W.C.--.02"W.C. and no more. If the barometric is wide open then the venter is pulling too much air and needs to be adjusted. Should be some kind of damper control on it to slow the air down and bring draft within normal ranges. Normally the barometric should be about 50% open. Actually a CO or Carbon Monoxide test should also be taken because it provides information about the mechanical side of the burner no other test can indicate. The smoke test is your real adjustment tool after all else is confirmed. Either air band will adjust the burner but the outer one is easier to adjust first. Close the damper slightly, retest the smoke. Repeat until you get a stain on the smoke paper, back off a hair and you are done. The CO2 bottle will tell you what you ended up with as far as fuel and air percentage. If CO2 is below 10% you either have too much air or too little fuel. It is 18 squeezes and tip the bottle twice. Tip it one more time to check the fluid. If the reading changes less than one line, .5% the fluid is still good. If it changes more than that it needs replacing.

Fyrite Bottle

Be very careful when inverting that Fyrite. Do not push the top as the fluid will leak out. The fluid is sodium hydroxide and if splashed on the skin or ingested is not only very corrosive, but can also cause liver damage, blindness among other things. Be aware.

Jim, Thank you for all that you have stated. This is all the info I needed. I have set up this and other burners in the past. These results were immediately after this years cleaning. I have adjusted the burner according to manufacturers specs. I can understand the PV adjustments now that you have explained. The reason for all of the other questions was to verify what I already expected. The fyrite needs to be changed. Thanks for taking the time with your knowledge, as I stated I am qualified to do this. I really did not expect the replies I received. I did not think my questions were unqualified. Again Thank you.
