If you’re going to be doing a vertical installation and going up through the roof and doing that on the outside of the house, there’s actually two different ways that you can do it. The first way that we’ll go over it is, you again take the three inch pipe adapter and hook that onto the back of your appliance and secure that with a clamp. Hook on your three inch diameter pipe, go out through the wall using the wall thimble. And once you get to the outside of the house, you would install what’s called a three inch to four inch clean out tee. And you want to make sure you have your clean out tee so that you’re able to take the cap off and clean your venting out as you go vertically. Otherwise you would have to take your whole venting system apart. But you would attach this on to the venting and then you would go up from there through the roof and terminate.
Now if you wanted to start off with four inch diameter venting right away off the back of the unit, you would use a three to four inch pipe adapter. And so you would go onto the back of the stove put your clamp on, then what you would do is you would hook this directly onto your four inch pipe. And then using a four inch wall thimble, you would go out of the home and then at that point, you could either terminate if you are doing a horizontal installation or you could put on a four inch clean out tee and go up and out through the roof of your home.
One thing that’s very important no matter how you put the venting together, whether it’s a vertical installation, whether it’s a horizontal installation, you want to make sure that you have adequate clean out tee’s and ways to clean the venting so that you don’t have to tear the venting completely apart every time you want to clean your appliance.
You want to make sure and check your venting at least once a month to make sure that it’s free from debris. And make sure that you take your clean out tees off and clean all debris out from the chimney system. If your appliance has been installed correctly, and if your home is balanced and you have fresh air hooked to the unit, you could get by for several months without cleaning your venting system. When you’re installing a MagnuM fireplace insert or Country Flame fireplace insert, you want to make sure that the venting configuration is designed from the beginning for ease of maintenance, ease of installation and so that it won’t come apart when you put the appliance into the fireplace.
What we’ll do in this section is explain a few things that can be done. When you’re designing your fireplace insert, and if that fireplace happens to be on the outside of the wall, you may want to terminate the venting by cutting a hole – access hole through the back of the masonry fireplace and go right outside so that you can have a vertical termination. And then seal off your chimney. But if you need to go up the chimney as in the case of the chimney being on the interior of the home, you’re going to want to prepare things. And the first thing you want to do is clean the chimney system. So call up yourself a professional chimney cleaner, have him come in, and have him check the chimney for cracks and things. Clean it out very well. Clean the entire fireplace opening. And then seal it so that you won’t get any of the old creosote and smoke smell that was in your wood burning fireplace. Once that’s been done and your fireplace insert is ready to insert in, there’s a few things that you want to do ahead of time to assure that you’ll be able to get the fireplace out. And the first thing is, is design your system so that the venting will be flexible. And typical installation would be, depending on the appliance is you would, again, hook on the three inch adapter onto the back of the unit. Or in some cases, you would want to hook on the three to four inch adapter. Because if your chimney is thirty feet tall, you’re going to want to switch over to four inch.
Our manufacturer’s recommendation is, is that immediately after you leave the fireplace chamber, that you would go with four inch liner all the way up and out the chimney system. This is not a code requirement but it is something that we as manufacturers would like you to do to get the best benefit and to make sure that you don’t have operational problems. So typically what would happen is you would hook a clean out tee onto the pipe adapter or you can use a special clean out tee that has the adapter built right into it. And you hook that on to the back of the unit and secure it very tightly. Make sure that your clean out tee is sitting at a forty five degree angle coming off the back of the unit.
The reason you want to do that is when you hook the flex tubing that goes onto the unit onto the clean out tee, you want to be able to flex this thing in different directions so that it can go up from the back of the unit up around and go up the chimney system allowing enough flexibility in the system so that you’ll be able to pull the unit out should you need servicing in the future. You want to make sure that you have some type of a flex in kind of like an S curve that’s built into the flex system so that that unit will move in and out of the unit freely. Once that’s done, you could put rigid pipe or you could hook flex liner onto the end of this system and go up and out the chimney system making sure that you seal both the bottom and the top of the chimney and insulate the top two feet of the chimney system.
You’re also going to have to make sure that you can route your fresh air safely and adequately. The best way to route your fresh air is go down and out the bottom of the fireplace insert and out through an ash dump or out through the back of the existing fireplace. If you have to go up through the chimney system, make sure that when you go up and out that you do not terminate the fresh air close to the exit for the exhaust or contaminated exhaust will come down the fresh air and into the system and it will contaminate the fire.
There are several types of termination caps that you would put onto the top when you terminate a fireplace insert. This is a typical one here. It’s called a vertical termination cap. When you put these on, you want to make sure and check them periodically through the winter to make sure they don’t fill up with debris, birds don’t try to build something in there and/or it freezes over and causes the appliance to malfunction.

This is the written transcription of the video featuring pellet stove venting. If you have any questions, you should call us at 1-800-495-3196.
The MagnuM and Country Flame product line is listed for all types of Type L pellet venting. There are several different manufacturers on the market producing several different types and kinds of venting but they’re all approved to go on the MagnuM & Country Flame. You can get the standard type of venting that you see here where it’s stainless steel on the inside and galvanized on the outside. And these come in various grades. There’s what’s called the pellet grade which is the type PL. And that’s the standard type of venting that’s used for all pellet appliances. Today’s markets though require a wide variety of fuels being burned in appliances. And in particular the MagnuM & Country Flame appliances will burn corn and wood pellets, olive pits, cherry pits and a host of other new biomass fuels. So there has to be specialty type venting that works for this. Manufacturers of the venting have come across with what they called either a corn vent or a bio vent that will burn a number of fuels and not deteriorate the venting. Those pipes are available in different finishes like this particular bio vent here made by burner dolson, is a nice black finish. It’s also available in the galvanized finish. And it’s made to be liquid tight so it’s a very good pipe that was just introduced out on the market.
Simpson Dura Vent has both pellet vent and corn vent available. And now they’ve come out with a new bio vent that is more liquid tight so you don’t get the fly ash leaking out of the seams. And it will withhold the chemical reaction when you’re burning certain types of fuels , if the fuel is a little bit poorer quality, or if the fuel happens to have quite a bit of moisture. At this point what we’ll do is we’ll go through a few of the standard configurations and tell you just a little bit about what’s required for venting in your home to make sure that the job is done right. We strongly recommend that you use a trained professional when having the venting installed on your MagnuM or Country Flame appliance. Different municipalities, different cities, even different states vary in the requirements and the codes and the building codes in this. The manufacturer comes out with a set of instructions with every unit that tells you the basics. It tells you what the clearances to combustibles are, what the type of venting is to be used, it shows you a few illustrations on the different types of venting. But that’s only the basics. You need to make sure that you know what you’re doing or hire a trained professional to make sure that the appliance are installed correctly. If they do not get installed correctly, you could have problems with the actual operation of the appliance where it doesn’t want to run, or the vacuum sensors trip out. You could have problems with the venting plugging prematurely, or you might have trouble with the appliance just safely shutting down; and it’s a venting configuration problem.
So what we’re going to do is just touch just very lightly on a few things. The first thing you want to do when you have your unit installed is make sure that you have an adequate fresh air supply. There’s a fresh air hookup located on the back of every MagnuM & Country Flame appliance to make sure that you have the right combustion air so that your venting configuration can be balanced. Second thing you want to make sure of is that your home is actually balanced. Over Eighty percent of the homes in America today have a negative pressure problem. So an indoor air quality problem within the home. That can and will affect the performance of your appliance. It can be as simple as the fireplace sensors being just a little bit dirty or it can be that your appliance actually shuts down and the safety sensors will not make it operate. So make sure that you have adequate fresh air coming in. Make sure that your home is balanced. From there you want to make sure that your venting configuration is designed for the appliance, for the locale that your appliance is located in, and gauge for the type of altitude that you might be at.
The normal venting diameter that you will use in a typical application is 3 inch diameter. But in certain conditions you have to be able to switch up and use a four inch diameter pipe. Instances of that would be if you live in the mountains or if you live in high altitude areas. That’s where you want to switch over to four inch. And in the installation manual, there’s a graph in there that shows you at what altitude and under what conditions that you want to go to four inch. There might be other applications where you’ll want to go to four inch. One of those might be is if you locate your appliance in the basement of the home and there is a hard time getting the right configuration going out so your draft is poor. Then you’ll want to switch to four inch. If there is a question in your mind, just go to four inch right away and the appliance will work great.
Now, to show you a couple of the configurations to switching back and forth. This is a typical three inch stove adapter that would go onto the end of your appliance and then you put a three inch hose clamp on here. And this part fits right into the end of your tubing. And this shows a typical installation using three inch diameter piping that goes out through the wall. You have your length of pipe, a wall thimble that goes into your wall to get the required clearance to combustibles. And then when you go outside, you have your required – you have your required twelve inches of space and some type of termination cap. This is called a horizontal termination cap but there are several different variations on the market. And so you can choose which one fits your application. If you are deciding to up to a four inch diameter off of the unit and you are using a straight out the back installation, then you would use what’s called a three to four pipe adapter. So the same pipe adapter fits on the back of your appliance. Put your hose clamp on, tighten that down and then this would hook on to a four inch diameter pipe something similar to this. And then you would put your four inch wall thimble on and go out through the wall and hook the appliance up with a termination cap.

Today’s post is a simple reminder to keep your vents clean.
Even if you are burning quality corn or wood pellets, fly ash can build up over time. You want your appliance to burn as cleanly and efficiently as possible, and we want that for you too!
Proper Vent Maintenance
- Always check to make sure your stove is getting adequate fresh air. Check the outside of your fresh air intake that landscaping hasn’t grown too close, snow hasn’t piled up, ice from moisture has not closed up the opening, or the wind hasn’t blown debris where it will block adequate fresh air.
- Clean out your exit vents on the outside of your home, again removing any soot or foreign debris/snow cover so air can move freely.
- Clean out the Tee vent behind your stove. Soot can build up there too. Be sure to place a rag or container underneath to catch any soot that falls and avoid any mess.
Venting should be checked monthly but might not need to be cleaned but a couple times over the winter depending on installation, fuel and operation. Make sure to re-seal any connections moved or taken apart.
Wasn’t that quick and easy?
