Jan,
Thanks for your prompt
response.
My first thought upon
hearing of a leak from the burner was that there was a problem with a rubber
component such as a seal. (I had been assured that, since the burner was
installed in 1992, the seals were all synthetic and would not leak). If that
were the case it should still be leaking, no? More than two weeks after the
nozzle was replaced and the blast tube was adjusted there is no sign of a
leak.
The explanation for the
puddle of oil (from the service man) was that the clogged nozzle was not
spraying all of the oil into the ignition spark. The furnace was not burning all
of the oil being sprayed though the nozzle. Unburned oil was dripping down the
blast tube.
I also considered that the
jelled BD should be trapped in the filter (and possibly clog it). The filter is
located at the tank. There is no second filter in the frunace. My concern is
that the fuel travels 12ft through narrow copper tubing along the floor at an
exterior wall in a basement that currently is 45F. Could it be flowing through
the filter, only to cool further inside the fuel line on its way to the
burner?
I didn't see the jelly on
the nozzle so I can't comment on its appearance.
There was an add in the
local paper for Biodiesel Heating Fuel. The add stated that it could be used in
any burner that used heating oil. I appreciate your help, as one of my goals is
to provide low cost .. as in free ... heating oil to people in need in my
community. I have to get it to work in my own furnace first.
Thanks again,
Tom
