I was wondering if anyone could tell me what the difference is between B-Vent and Type L doublewall?

\"L-vent\"
can be used for oil- or gas-fired units, whereas "B-vent" can only be used with gas.
L-vent is more expensive, but wouldn't need replacing if you switch fuels.

Thank you. You said there is a price difference. Im guessing this is due to the type of materials used?0 -
L vent
Type L vent is listed to UL 641 and was originally developed for oil. However, most L-vent is now sold for use with pellet stoves. The inner liner is 300 series stainless steel whereas B-vent uses 6006 aluminum. The outer jacket may be galvanized steel, Galvalume or stainless steel. Lvent has a fiberglass rope packing in the female end. L-vent is rated for 560F and a higher corrosion resistance than B-vent, which is listed to UL 441 and rated for 480F. The clearance on Lvent varies from 1-3 inches for most brands while B-vent is 1".
You must use the same brand of components and not mix & match.
