I tried to post this before, but it never showed up. If it gets
duplicated, I appologize.
I have a 7 year old Bryant oil furnace. I have had problems with this
furnace since the first 3 months it was installed. Prior to this one,
there was an oil furnace that was 13 years old that blew a hole in the
heat exchange and subsequently blew oil and soot all through my house
resulting in total restoration.
I have this furnace serviced every year, and within the last 13 months
have dumped over $1000 into it in service/repair....not to mention the
The last service date was 2 days ago. After spending almost $500 on
it, it still is not working.
I have a 550 gal oil tank that is underground.
I have a single copper line that runs from the tank to the furnace (not
sure why it wasn't installed with a 2 line system.)
I have a filter on the outside of the furnace.
A new nozzle, new cad cell eye
A new primary control
A new 5" elbow (replacing 7 year old one that was corroded through)
When the service man left on Friday, the unit was working and all
diagnostics came out passing or better. One hour after he left, I lost
the prime in the copper line. I bled the unit until the fuel ran
solid, no sputtering or bubbles. This took a little more than half a
gallon to do. I hit the reset, the burner lit, the blower started, I
heard the burner go out, the blower kept running, I killed the unit
before I killed myself or anyone else.
I do know how to bleed the line to get the air out, but at this point I
am not sure where to go. I know better than most people who have
posted on alt.hvac....I leave the repairs to the pros who know what
they are doing.
The service company told me I probobly have a leak at the tank since I
can not keep a prime. To check for this leak, I am told I have to dig
down to the connection. This would entail digging up my deck and part
of the tank. Before I do this, I just need to know.....and no one
seems to have an answer for me....is there a way that I can check the
copper line with pressure? I would assume that there is a way to
pressurize that line to check for an air leak without digging up my
yard and demolishing my deck?
Any help or suggestions?
