    Default Oil Fill

    Is there a code for the distance an oil fill is required to be set away from other exterior mechanicals, Like air conditioner units?

    The only thing I can find is "Outside fill pipe min 2ft from building openings & equipped w/tight metal cap" nothing about distance from equipment. Inside tanks need to be 5ft from any flame/fire/appl, but nothing about the fill piping.

    Thanks Brent, I imagine there will be more damage from the overweight delivery man sitting on the units than from the fill hose anyway.

    Five feet?! Yikes. I thought it was ten.

    I don't know about the oil fill or its access, but those disconnects for the condenser units are not allowed to be where they are.

    They require a working space of 30" wide by 36" deep in front of them. Additionally, I doubt those clearances on each side and between the condenser units is sufficient either.

    You've got a fresh air/combustion air intake on the side of the chimney to the left of the left disconnect.

    Those pads the condenser units are setting on look like flotation devices, not like concrete pads. Also do not look high enough above finished grade either.

    2006 IRC does indeed say 5 feet.
    Maybe 10 feet is a Pennsylvania thing.
    We don't allow copper fill and vent pipes, while the IRC does. Not that the ones in the photo are copper.

    Yes Jerry.
    I know about the clearance issue. What are you thinking is the problem with the air intake for the fireplace?

    Just in case there were any other requirements regarding that.

    Thanks Jerry. Beyond 2 feet. I had posted in the past on how another fill was very close to a fireplace intake vent with no real answers.
    I think that one was in the 2 foot range

    So what do we need as far as clearence for the coils? 12 inches? If so, then do two units side by side like those in the picture need to be 24 inches apart? That, giving each one its own 12 inches of space?

    Typically, yes, according to the manufacturer's installation instructions I've read.

    However, there is one, forgot which one, which allows that separation between adjacent condenser units to be reduced to 18" (18" is what I recall, may have been 12"???), but only on one side.

    In other words, if you have three condenser units (or more) then you could only reduce the space between two of them, the space between the other two would still need to be 24" as well as the spaces on the other sides not being reduced, and, of course, there is the 30" by 30" working space to the mechanical service panel and the 30" by 36" working space to the electrical service panel (the two of which almost always overlap, leaving the larger of the two (the electrical working space) the required minimum size - that does not look like it is there in that photo.
