A: 4BVKNT has 4 total pipe lengths, (1) 12" and (3) 24" lengths.

A: No, the DuraVent 4BVKNT Vertical Unit Heater Kit is strictly designed for Category I gas-fired appliances (natural gas or propane) and is not compatible with fuel oil furnaces. Fuel oil systems generate significantly higher exhaust temperatures and corrosive soot that require a Type L or Type HT venting system, whereas this kit uses Type B gas vent material intended only for lower-temperature gas appliances [1]. Using a Type B vent with a fuel oil furnace creates a serious fire hazard and will lead to rapid deterioration of the vent pipe.

A: No, you cannot use the DuraVent Vertical Unit Heater Kit, 4BVKNT on a Grand Teton pellet stove. The 4BVKNT kit is a Type B gas vent system designed for gas appliances, which is fundamentally incompatible and unsafe for use with a pellet stove.

A: No, the DuraVent 4BVKNT Vertical Unit Heater Kit is not for wood stoves. For a wood stove installation, you must use Class A Chimney Pipe (often called "All-Fuel" pipe). Look for the DuraTech or DuraPlus lines, which are rated for wood stoves and can handle temperatures up to 2100°F.

A: The DuraVent Vertical Unit Heater Kit, 4BVKNT, includes vent pipe sections of two different lengths: Three 24-inch galvanized pipe lengths and One 12-inch galvanized pipe length.

A: Hello, thank you for your question. Per the vendor, "The sizing of Type B Gas Vent is based on several things: • Individual Appliance or common vented? • Is appliance Fan-Assisted or does it have a Draft Hood? • Are these the only components being used? Or are other pipe lengths or elbows being used? If this is an appliance with a draft hood and there is a total height of 7’, with 2’ or less lateral, this can handle 67,000 BTU/Input. If this is a fan-assisted appliance and there is a total height of 7’, with 2’ or less lateral, this can handle 97,000 BTU/Input. The NFGC Sizing Tables are used to determine proper sizing. For more specifics, contact our Technical Support Team at 800-748-0392 x 5."
