I have a wood-burning fireplace that has a zone heating kit. It calls for B-vent pipe to run from the fireplace to the heat vent. Is there a substitute for B-vent?
By Collin C. - NFI Master Hearth Professional on December 23, 2012
Answer:It is likely you could use either a rigid or flexible B-vent pipe to accomplish this, but it must be one of the two. B-vent piping has a dual wall setup and would be needed for proper clearances. We carry a large line of B-vent piping manufactured by Simpson Duravent and Metalfab.

I have a Mr. Heater 80,000 BTU heater mounted in my garage. I need to run my vent pipe for it. How does the type B pipe connect to my heater?
By Kevin E. on September 11, 2014
Answer:Most all B-Vent appliances have their pipe connect to the appliance by way of a draft hood connector. These connectors are pipe specific and are tapered at the bottom to slide into the flue collar on your appliance.

I have standard 6" black single wall stove pipe on my shop wood stove, rising 20 feet up through the metal roof. It is all open space, with no second story floor in this section. I need a cap to replace the type of rain cap on top. Do I use b-vent or what kind of cap?

I currently have a 12" diameter Type B Double Wall twist lock flue pipe, surrounded by a fake chimney above the roof. I want to remove the fake chimney, do you know if I need the fake chimney to support my pipe? Will I need a brace? Will my pipe leak into my house?
By Collin C. - NFI Master Hearth Professional on April 23, 2013
Answer:Due to the diameter of your piping, it is likely that the pipe will be self supporting without an issue. It is recommended that a brace be used if the pipe projects 5 feet or more above the roof. The pipe is designed to be air tight and will have at least one inch of overlap at each pipe joint. As such, water should not make its way into the pipe if the sections are attached properly. You should only need to add a roof flashing and storm collar in order to complete the transition to a free standing pipe.

Can I put a B vent through a wall? Do you sell black B vent chimneys?
By eFireplaceStore on September 8, 2014
Answer:Type B gas vent pipe can indeed be vented through a wall using an approved thimble. While the pipe itself is only available in unpainted galvanized steel, it can be easily painted using a high temperature aerosol coating.

I needed to break down a 8Ē vertical B-vent for a gas fireplace, for renovation of the area. I am now trying to re-install it. I am having trouble getting the pipe to go back together. I get the inside pipe to fit but canít get the outside to slip on. Any tips or tricks?
on November 9, 2012
Answer:Do you know the brand of pipe with which you are dealing? Does the pipe feature twist-lock connections at the ends? You mention an inner and outer pipe. Are they two separate pipes? If so, what is the dimension of the inner pipe? We look forward to your response.

Can Type B Vent Pipe can be used for an oil fired boiler? Can you please tell me which type of pipe I have to use for this oil fired boiler? The pipe must be run straight up to the roof inside of the house.
By Collin C. - NFI Master Hearth Professional on September 20, 2013
Answer:Oil fired boilers and stoves create highly corrosive flue gases. As such, type B vent pipe cannot be used. Class A chimney must be used to vent this type of appliance.
