Smell of oil

Bruce Stevens

over pressurize the tank when filling, required is inch and a quarter fill minimum and vent no smaller than the fill. I know we were required to go to 2 and 2 two for a bit but subsequence testing has proven inch and a quarter and inch and a quarter are fine we how ever do go inch and a quarter fill inch an a half vent.

oil smell

What would cause a stong smell of oil? There are no apparent leaks and the smell is stonger in the room that is behind the boiler, adjacent to the chimney?

Any suggestions are appreciated.

I was thinking...

Oil?

Did you just get an oil delivery? I have noticed the same sort of thing with no leaks, but sure enough there's a bill in the mailbox.

Perhaps?

Sometimes a customer will confuse the smell of raw oil with that of burned oil (products of combustion). It could be that your boiler or furnace is operating incorrectly or the flue could be plugged. I would have it checked out just to be safe. Just a suggestion.

Double check

For oil leaks!!!

Also, take a look at the oil tank vent line, it should run out the house maybe there is a problem there such as the line broke somewhere.

The size of the oil tank vent line should be the same size as the oil fill line.

I always see a 1-1/4" or 1" vent and then a 2" fill. I was always taught to do 2" fill and then 2" vent, I never knew why though. I'm assuming the tank will fill better but I never really got an exact answer

just think oil in air out. Same size fill and vent helps eliminate pressurizing oil tank, which by the way, was not designed to be pressurized like that. Ever been home when they fill your tank tooo fast and hear oil tank expand? Sounds like someone hit tank with hammer.

K.I.S.S.

Why bring 2 sizes of fittings and pipe to the job? What do you save by not running the same size? Not much in my opinion.

I have heard that it is now acceptable to now use down to 1 1/4 but I already have 2" stock on hand for now. Will look into using the smaller size when I deplete what I have on hand.

In & out...

Around here, they always use a smaller vent than fill line. Why? Because air will compress, not so liquid. In case the vent is some distance away from where the delivery is made, the oilman can hear the whistle change as the tank is almost filled. Probably applies to comm'l settings more often.
BTW, is this ofor a recent thing? I would have it checked anyway. About that time for a cleaning/adjustment, no?
