Another fuel oil tank question

Do it all the time !!!! Easier to drill wood than cement. As long as you meet clearances to fill and vent and no local codes prohibit drill the rim joist, go for it.

Fill and vent line.

My fill and vent line currently penetrate the basement wall to the outside of the home at the top row of concrete blocks. The top 2 rows of concrete block are 4 inches thick with a 4 inch wide stone exterior making for 8 inches total. The top row of block and stone is the only row of block above grade at this location. The concrete block that was penetrated was not a full block and is right against the frame of a 16x32 basement window. The penetration was made right on the joint between the half block and a full block. The block is busted badly and needs repaired. The window is on the left side of the block and outside the house there is a stone porch on the right side. There isn't any room to move these pipes left or right at this location. Can the fill and vent pipes be put through the Band joist?

Thank you Mr. Al Letellier.

I thought maybe there was a code or structural issue with drilling through the rim joist. I can't figure out why the original installer did not put it through that way. As you stated, the wood would have made an easier, professional looking install. As far as clearances go, current set up is 2" fill with 1" vent about 1.25 inches above it. I would like to put my dryer vent through the rim joist also. it is currently vented through a basement window that has the pane removed and replaced with thin plywood. Would that be a good idea? I would like to replace all of these basement single pane windows but I need to address these 2 issues first.

You may wish to increase vent size to 1 1/4" to bring up to NFPA 31 standards (table 7.5.9)

Edward A. (Ed) Carery

NFPA Standards

NFPA 31, 2006


Table 7.4.8
Capacity of 660 gallons or less. Min vent pipe size 1 1/4"



8.3 FILL PIPING

8.3.2 The fill pipe shall terminate as follows:
(1) Outside the building at a point at least 2 ft. (0.6M) from any building opening at the same or lower elevation.



8.7 VENT PIPING

8.7.5 All vent pipes shall terminate outside of buildings at a point not less than 2 ft. (0.6M) measured vertically or horizontally from any building opening.

8.7.11 The vent of a supply tank shall terminate at lease 5 ft. (1.5M) from any air inlet or any flu gas outlet of any appliance.

Watch the clearance to that window, and also the exhaust from the drier.

Thanks for the education, Mr. Carey.

I had tried to research the info but had no luck finding it. I don't know what to do now. I have only lived here 2 years. The tank looks like it had been installed at this location for at least several years. The vent and fill exit the wall 8 inches from the window and 20 inches from the back door. I should be okay on the dryer vent. It is located in another room on the end of the home about 20 feet away. Also, I failed to specify that this is an electric dryer.
