weil mclain 80 series

Joe Falzarano

I have a Weil Mclain 480 oil fired with a Carlin burner that I am having a sooting problem with. Boiler installed 2/03, used for balance of season. Fired in fall for a few weeks and was quite sooted. I cleaned it in 11/03 and now requires cleaning again. Have been over adjustments several times and phone contact with both Weil Mclain and Carlin technical. I am wondering if anyone else has installed one of these with same problem? The burner seems to start "hard", there seems to be a great deal of expansion upon ignition. This has been present always. Any ideas?

Sounds like

You need to have an oil guy set it up correctly....Could be a problem from dirty filters to poor draft...to wrong adjustments. We do alot of setting up of equipment for plumbers. Carlin is a nice burner but needs to be setup correctly.
Good Luck

80?

What are you firing it at? I found if you under fire them they will stay cleaner, longer. Sometimes i'll go over (size) then under fire. Weil-McLain has no official opinion on the topic, they claim you can fire it at the max. I've learned different... good luck.. It is also important to set up the oil right, u may need help..BoC

We have

80 Series Weils fired w/ Carlins, Gordon-Piatt G/Os, & a Riello G/O. Sweet operation except for the difficulty getting the flue collector sealed completely.

The 80 is a positive pressure (forced draft) boiler. The index on the adjustable damper can be confusing. The HIGHER the number on the index, the more OPEN the damper is. If you are venting into a chimney, a barometric is almost a necessity. W/O a device to stabilize the draft @ the boiler breech, that +.10" WC pressure at the damper in January, can be +.15" in March. More pressure reduces the air volume the burner fan can deliver. Excess pressure = hard starts. Less air = soot.

Looks like a set up, after the cleaning, with instruments and a good draft gage is required. Good luck.

I have found

these boilers to run pretty good with the Carlins when set to spec. If you have good readings on draft co2 etc I would suspect a lack of combustion air.

All the best ,

pump pressure

Hey Joe, has anyone suggested you check the pump pressure. If your pump pressure is set greater than 100 psi(and it typically is), then you must use a nozzle smaller in size than the firing rate recomended by the boiler manufacturer. Check for a nozzle reference chart posted on the burner.
Good luck

combustion air

If you have checked out the burner set up and all appears well then.....Lack of combustion air gets my vote as well.
