My adapter bottoms out of the outside of the adapter on the stove before it tightens up in the flue. Should I trim the outside of the adapter or is there an easier way to fix this problem?

Answer:In this rare situation, it will indeed be necessary to trim the adaptor to get a better fit. The adaptor does not need to have an perfectly tight fit, but it should be snug.

I have a Martin Wood fireplace with a 12" exhaust and I would like to adapt that to my flue which is 8" Triple Wall. Do you make an adapter that will accomplish this?

Answer:Unfortunately, adapters to change the size of Class A chimneys are not manufactured. This is because any change in size will likely cause the unit to backpuff smoke into the room, as the chimney will be improperly sized to the opening size of the unit. Different size chimneys are also not listed to be used with one another, so a fire hazard can result.

I can't get the wrinkled part to go into the portal on the top of the stove - it is slightly too large. Yes, the stove outlet is 6", and my adapter is 6". Can I make some splits with tin snips, maybe 1/2" long, around the bottom of the adapter, to help get it started through the portal? I already tried filing some welding burrs off, but still can't get the crinkly thing to start through.

Answer:Trimming vertical cuts in the crimped surface is indeed necessary in scenarios where the flue collar is smaller than average. Five or six cuts made at equal distances should compress the surface enough.

I am using this adapter for Lopi Liberty stove. The adapter does not fit snug within the stove's collar. On Dura-vent's website the dimensions of the inner crimped portion of the pipe are 5 and 5/8 inches. The stove collar's internal dimensions are 6 inches. This is the reason for the poor fit. Is this OK? Why does Duravent not make them 6 inches internal to fit 6 inch diameter flue pipe?

Answer:Both the DVL and single wall adapters are manufactured to have a slight taper on the crimped male end. It will start at the 5 and 5/8 inch measurement you mention and end at 6 inches, at the top of the crimping. Many stoves have flue collars that measure slightly under 6 inches, so the adapter is tapered for a better fit. Unfortunately, it sounds like the adapter bottomed out before reaching the larger end of the adapter. Once the chimney system is in place, there should not be an issue, but a rope gasket can be installed around the inside perimeter of the flue collar if you wish a tighter fit.

I am buying a wood burning stove and it says I need standard 6" stove pipe for the flue. I need to know what distance the walls or enclosed space needs to be from the stove pipe. We will be putting it up through our roof and need to know how many inches it needs to be from the walls thanks. Also what kind of stove pipe do I need, I think I will need something to go through the roof not sure what.

Answer:Inside the room that the stove is installed, you will need to use single or double walled stovepipe. Single wall pipe requires 18" of clearance to combustibles, while double wall pipe reduces this to 6".
Before passing through the ceiling in the room, you will need to convert to Class A chimney, using a ceiling box. Class A chimney has a 2" clearance to combustibles and is used to pass through the attic and the roof decking. You can then install a roof flashing, storm collar, and cap to complete the installation. Please let us know if you would like a quote to be assembled for your installation and we will be happy to help.

How do I attach to a double wall pipe when the male is supposed to be facing down?
By eFireplaceStore on October 14, 2014
Answer:After the adapter, the next section of DVL should be installed with the flared outer wall facing down. The flared outer wall will overlap the outside of the adapter and the inner wall will push down inside the adapter.

I have an Earth Stove 400 series. Would you have an adapter to fit my stove? 6-inch pipe.
By Collin C. - NFI Master Hearth Professional on February 27, 2013
Answer:From the information I was able to locate on your stove, it appears to have a standard 6 inch flue outlet. As such, the DVL adapter you are viewing would work if you plan on using the Simpson DVL stovepipe for venting your appliance.
