DuraVent Model BV Oval 45 Degree Standard Elbow: a fixed bend for moving an oval vent sideways
The DuraVent Model BV Oval 45 Degree Standard Elbow is a fixed bend for an oval gas vent run. Use two to move the vent sideways around framing and return it to an upward path. A pipe length between them gives you more sideways reach. The pair can sit in an enclosure with the needed clearance or in an open attic or basement. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
Choose 4, 5, or 6 inch to match your oval vent. The bend stays at 45 degrees and does not adjust. An aluminum inner pipe sits inside a galvanized steel outer pipe, with air between them. Keep 1 inch of open air between this elbow and anything that can burn. The special allowance for straight oval pipe inside a stud wall does not apply to elbows. Leave installation to a licensed installer and your local inspector. Comparing the other oval bend? See the DuraVent Model BV Oval 45 Degree Flat Elbow.
