Burnham v8-2
Ok fellas ran into a saturday nite trap. Last nite had a no heater new customer (new fuel account), plugged boiler 5 year old V8-2. Never ran across this little guy before, have work on v8 -3s and 4s. The riello was setup with no air, over 15% co2( i think the HO got his hands in there) the turbulator was the wrong setting, pump pressure wrong, ect. After the 11pm brush and vac, noz, o/f and reading the plate and seting this back were things belong i had a crazy hot stack over 680 f. Turn the air down to 13.1 co2 , draft wasnt too high soild -0.03, still high stack 628
unit fired at .50 80a current settup 13.1co2, 28%ex-air, -0.03, 81.7% 3.2o2, O smoke. Pump 145, all other setings where they should be. (dont really like pushing the burner that rich)
Unit vented with 5'' smoke pipes 2 elbs, 4ft total. INto a 5'' prefab up through the middle of the house maybe 18ft total. Nice piping job all 1'1/2'' pipe with 2 taco 007 pumps. Only an air handler and boilermate indirect.
Burner man common sense tells me theres not really much heat exchange with only one section. Do these little guys always burn so hot??? Im going back in a few weeks to fix up the wild looking oil tanks that are mangled together. And thing else to check?
lousy boiler
2 section boilers are the worst. I prefer taking a 3 section and fire according to load. Not just a burnham thing, I've ran into others. Riello is not a good choice for that boiler. I have found Beckett AFG, F-3 head, low firing rate baffle, 120-130 psi .50 80A is the only way out of that bad situation.
I agree with Bill on this one.
2 sections is crap.
Riello is also a bad choice. AFG as mentioned. W/M used to have a 2 section didn't they? Anyway the 368 had the same problem.
I would try to push these folks to a modulating gas unit. If the heat load is that low, Yikes.
Good Luck man.
