Questions people ask us
Can I use this on a wood stove, pellet stove or oil furnace?
No. Duravent lists Model BV Type B gas vent for listed natural gas or LP Category I gas appliances with draft hoods and appliances listed for Type B vent, with flue gases up to 470°F. Its catalog warns that oil or wood burning appliances can damage the vent, and it is not for Category II, III or IV gas appliances. Wood and pellet appliances need a chimney or vent system listed for them.
How do I work out the installed height?
Add up the pipe lengths, then deduct 1-1/2" for each joint on 5" to 8" pipe, or 1" per joint on 10" and 12" pipe. Use an adjustable length to hit an exact height.
What does the -1 at the end of the 10" and 12" part numbers mean?
In Duravent's current Model BV catalog the 10" and 12" parts carry a -1 suffix, for example 10BV12-1, and join with the DuraTab method: align the notches, slide together and press in the tab. Duravent's earlier catalog listed the same sizes without the suffix and with a DuraLock snap-in joint. Duravent's instructions do not cover mixing the two, so ask us before joining a -1 part to older 10" or 12" pipe.
Will it fit my existing vent?
It fits Duravent Model BV pipe and fittings of the same diameter. Duravent sells universal adapters for other brands of round Type B vent. Send us the brand and size and we will check before you order.
Who should install it?
Duravent warrants the vent fully only when a professional installer puts it in. A licensed gas professional should install the system to Duravent's instructions, NFPA 54 (the National Fuel Gas Code) and local codes. The appliance manufacturer's manual decides which venting is approved and the vent size and layout, so send us the appliance model and we will check.
