brazed fittings ok for oil line?
The supply line between our fuel oil tank and the furnace includes about a 25' run of rigid copper tubing, the copper fittings (elbows and couplers) of which are brazed. Here's a picture where you can see part of the rigid line installation with a few brazed elbows: http://i207.photobucket.com/albums/bb153/sgull1/IMG_2098_zps88175536.jpg
An HVAC pro who noticed this informed me that brazed fittings on a fuel oil line is usually against code and he seemed surprised that the installer would've chosen this method for the supply line. I myself know next to nothing about brazing, but anyway he said something about he thought the reason brazing is considered unacceptable had something to do with the phosphorus content of the brazing rod, alloys, and/or flux used can have a corrosive effect on copper. Any comments about this please? Advisable for me to get this run of line replaced with soft copper tubing? Thanks
