I have an oil-based hot-water system running a Lennox Furnace with a Beckett
burner. Ever since the system was installed 15 years ago, the furnace has
burned with a loud rumble, louder than any other oil furnace I've
encountered. I have the furnace serviced annually by a pro(filter, nozzle,
cleanup)who claims that nothing can be done to quiet the furnace down. Also,
about every winter or two the burner conks out with carbon deposits fouling
Anyway, I was complaining to a friend about all of this and he said he had
the same problem with his oil furnace on a hot air system. He said he
quieted his furnace down by moving the electrodes out "just a hair" further
from the nozzle and suggested I give it a try. Before I do, I'd like to ask
a few questions.
Has anyone tried this, and did it work?
Is there risk of damage to the electrodes, maybe burning them out by raising
the combustion temp. by moving them?
How critical are the specs on the electrodes -- gap distance, angle to the
nozzle, distance from the nozzle, etc.??
I'm willing to give his idea a try, but want to make sure I'm not going to
mess things up worse than they are and have my furnace go out on the coldest
night of the winter.
TIA for any advice.
