first post, need some help. I had my boiler serviced a month ago and while the service man was there I noticed an oil stain on the floor right where the line comes out of the concrete which is about 4 foot from the burner and 10 foot from the tank. It was never there before, I have a feeling the guy stepped on the line accidentally but he wouldn't admit it when asked.
I am (was a licensed plumber in california but oil burners are foreign to me so I am smart enough to call a professional licensed contractor.
I live in vermont, temps reach -30 at times and boilers and oil tanks are often located in the house.
I am new to the upper north east(left 27years ago and swore I'd never return ). came back 18 months ago.
My house was built in 1997. the oil feed line is copper 3/8 runs under the concrete and was sleeved through a piece of 3/4 clear plastic for about 10 foot under the foundation.
somewhere the line got pinched and started leaking. the oil repair man said just run it overhead and abandon the line in the ground as I probably couldn't get by the kinked area .
I ran a new line (couldn't even get the old one out)but had to increase the pump pressure to get good oil flow from the tank.
beckett says the pressure should be 140psi with the burner afg I have.
the boiler seems a little louder but looking in the fire box looks to be burning ok( I looked when the serviceman finished and it looked about the same.
is there any general rule of thumb setting oil pump pressure to get a good clean quiet burn?
I can borrow a pressure guage from my local supply house but I don't know what it should read.
it's a smith boiler with a .65 x 80 A nozzle 2 zone pumped system.
If I have to I'll have the guy who did the service come back out but I'd like to save the $75 dollar service call if possible.
the length of my oil line went from 20 to 40 feet going overhead up 7 feet between the ceiling joists.
any help most appreciated.
