Lyemance Chimney Damper Flue & Cap Install

- Installing a tap mount flue damper and new cap. Fireplace had no flue and was letting tons of cold air enter the house. This new damper seals at the top of the chimney. Much easier then the old metal on metal internal flues.

Did you at any time think about cleaning the creosote from the flue before installing the damper or cap?
Tank you for posting this video very very easy, and nice house
Oh man.
I've been in the chimney industry for 12 years and I have to say this an extremely dangerous set up.
I'm going to give you some free advice and I really hope you take it.
Take the damper off immediately.
Hire a professional and tell them you need an acid wash on that creosote glaze covering you're entire flue.
Chain flail may be too aggressive so 2 or 3 acid applications and a stiff wire sweep will work.
Next. And MOST importantly..
Install a stainless steel liner from the top of the wood stove to approximately 3 inches past your clay flue top.
12 x 12 top plate and cap.
A wood stove NEVER should have a lock top or lyemance damper.
Every wood stove insert calls for a liner.
Connect it directly to the top of the insert with an adapter.
Insulate the surrounding areas with ROCKWOOl insulation to cut off cold air from dropping.
At base, inside smoke chamber and also at top , right below the top plate.
If you leave what you have , you will burn your house down.
It's not if ...it is most certainly when.
Spend the money , pay a professional for any type of repair that involves fire and carbon monoxide.
You can take it or leave it.
If anything , call a local company for an inspection on your set up.
It is a disaster waiting to happen.
Good luck and I honesty hope you get this situation resolved in a safe and legal way.
So what would you recommend to prevent downdrafts when stove not in use???
@@terry2346 installing a vacu stack chimney cap , they are designed to stop down drafting issues.
Ummm....several things. First this stove insert should definitely have a proper stainless steel liner installed with top plate and rain/animal cover. This would help prevent the nasty 2nd/3rd stage creosote your developing in the flue. A properly sized liner will increase drafting and efficiency of the system making for a better burn with less creosote buildup. Secondly, with the top plate sealing the space between the new stainless steel liner and the original clay flue it would drastically help with downdrafts. Any drafts that do come down the new liner would likely be stopped by the gasketed door on the front stove. As an extra measure you can insulate around the stainless liner to help keep exhaust gas temperatures higher which in turn prevents the hydrocarbons from condensing (less creosote buildup) as well as keeping your home more comfortable. This would also prevent smoke spillage behind the surround panel (smoke stains on the painted brick were evident when you took the panel off), as no one wants to breathe in that toxic smoke when burning. As you are a DIY'er you can purchase a basic liner kit (single story home likely 8'-10' of 6"-8" diameter liner, stove adapter, top plate, rain/animal cover), most likely from the same place you got the Lyemance damper. This would probably be not much more than you spent on the damper system (probably $250ish) vs $300-450 for the correct liner companents. Also DO NOT BURN UNTIL THE FIREPLACE HAS BEEN PROPERLY SWEPT! The buildup currently in the flue is very flammable and you are at significant risk for a chimney fire. As a bonus sweeping the chimney after the new liner has been installed will be much easier. There will be no need to remove the insert or surround panels, simply take the rain/animal cover off and sweep top down. Clean up the soot/ash in the insert firebox and all done. As a chimney industry professional for the last 20yrs, there is a reason stove inserts do not get installed like this anymore....they are a safety risk. Dont take my word for it though, check out the resources available at csia.org. You can also find a certified chimney sweep/liner installer there as well. Good luck!
When I was a chimney sweep I tangled my fair share if top damper cables lol.
I finally learned to open it on the ground. Then tie the end off to something and unwind it slowly with tension on the cable. Ifnot it will spring into a rats nest.
Minute 6:27 up to 6:50 , you made my day hahahahahaha!!!! Good video man
You need to do a rotary cleaning to remove all the built up creosote.
Your at risk of a chimney fire. If you look at the little puffy pieces on the flu that is from flare ups.
When you read the directions or codes for top mounted dampers you will see this. The first two doesn’t apply to your application.
•*Don’t use on chimneys serving vented gas logs. Vented gas logs require the fireplace damper to be removed completely or fixed to a permanently open position; this is to assure that soot, fumes and carbon monoxide do not enter your home.
•*Use only on vent-free gas logs if approved by the appliance manufacturer and the local authority having jurisdiction. However, we don’t recommend it because the moisture generated from the gas logs could damage the chimney structure.
•*********”DON’T” use on chimneys serving other fuels, wood stoves or other appliances such as inserts, furnaces, etc.
I hope you’ve removed the top mounted damper and had that chimney thoroughly cleaned of all creosote glaze and deposits, and installed a stainless steel liner by a professional. I would even consider buying a new wood stove insert.
This is for the folks that seem to think their negativity about your video is OK and was solicited…..I live in a 200+ year old house,. It has six fireplaces with four chimneys serving the house and fireplaces. The chimneys are quite tall and have stood the test of time without having this and that inserted to make a flue for “correct/proper airflow” and being capped with some expensive concrete slab with a drip edge. And yes, my fireplaces all work beautifully, and are larger than most. The idea of adding a stainless steel liner to my chimneys seems so wrong and would serve no useful purpose that comes to my mind…the chimneys and fire boxes do require occasional attention for mortar and brick repair/replacement/attention internally and for cleaning, but as the old saying goes, they don’t make them like this anymore, and it’s well worth the small amount of effort every few years to maintain them and to keep them in their original state as much as possible.
My fireplace already has a throat damper (but a little air leaks from it)...if I install this unit will the cord/chain get in the way of the the throat damper closing?.. l want to use the throat damper in combination with the top chimney damper....can this be done? Thanks in advance for any info you can give me.
They suggest drilling a tiny hole in the lower damper to run the chain wire through it. Basically the seal at the top (on the new cover) becomes the only completely air-tight seal in the chimney.
call a chimney company and let them advise you of what should and should not do. don’t play with fire, or you know what can happen. don’t be cheap when it comes to safety, or the consequences will cost a lot more. be safe.
if you have two dampers installed, i would still call a chimney company, and tell them what kind of setup you have.
@@ginoasci That's what rich people do, but it's a waste of money for the average person. We are not talking about gas pressure ratings or fire wall installations here. This is a simple chimney cap to manage drafts and pests, all he has to do is drill a tiny hole for the chain. There's no "playing with fire" or danger involved here, sheesh.
@@jban4457 : ok, whatever you say
@@jban4457 : you don’t have to be rich to service a chimney.
if you can’t afford a couple hundred, you better examine your life
you need a proper drip cap made of concrete.
Thanks for the comment. What do you mean?
How to fix anything, but when someone tells you something you say what? Would suggest you take down sight and don't give anyone any advice.
