Hello all again, One thing we've had to do recently is up the temp on the furnace b/c the temp in the house is toooo coold (chattering teeth). Now when she comes on she burns for a bit, then starts to hum, then starts to whine. I read elsewhere here, that it might have to do with a dirty system, and we've just changed the expansion tank. Any ideas? -S:confused: 125k JVS Laars Teledyne 2 zones 3 story house.

Hello, I have an original american standard hydronic heating with original oil burner (1948). This past year the burner started to smoke a bit and the techs said it was not getting enough combustion air. It is an Ideal Model DF6 Arcoflame oil burner. The rest of the furnace is in reasonable condition, given its age. I want to replace the burner with a beckett or similar burner and add an inline oil filter. There is only one zone. My questions are as follows: Which Beckett model should I choose, NX, AF, AFII, AFG? Which controller? How do I make sure the transformer is safe to disconnect? Will the new burner mount on the same three bolts? How do I select the correct size air tube length? Currently it is using a 1.0 gal/hr 60 degree nozzle, should I maintain this rating? I know I should replace the entire unit, but that is really not an option right now. I only burn about 200 gal per season. Thanks, Lou
