Where can I find Temco fireplace replacement pipe? Had a chimney fire. Need 22 feet. Model #TCH4125 serial #AF291082
1 Answer
Unfortunately, we do not have any Temco chimney available as this company has been out of business for quite some time and all stock of their manufacturer-specific chimney lengths have been depleted.

I bought a used gas fireplace/stove that came with more chimney vent pipe than I will need to install in my manufactured home. The double wall vent pipe chimney is 7" diameter with a 4" pipe inside. The chimney will go through the ceiling and then through the roof. I believe it will be exactly vertical from the stove through the roof with no bends. Can you tell me what to look for in your store for a piece to keep the vent pipe away from the ceiling and going through the 4" of insulation above?
1 Answer
That would be an Attic shield

what venting parts are needed for the mirage outdoor with BBQ
1 Answer
If you are referring the the Mirage Stone line of outdoor fireplaces we offer, these should not be connected to any chimney system and should simply be placed at least 10' away from a home or structure and not underneath any sort of covering.

I am constructing a class B-type flue system for a Williams furnace 6551921. I plan to place it on top of a wooden room in my all metal RV barn. It is 60" to the metal roof and I have obtained 7' of B-type exhaust piping. Is there any recommendation on how to deal with the area where the flue pipe goes through the metal roof?
1 Answer
If you are going through a metal roof without contact to combustibles along the way, then you only need to cut out a hole with the proper clearance required for your pipe as listed by manufacturer. Above the roof, you will need a flashing, storm collar, and cap.

I have a direct-vent gas fireplace and live in a very snowy area. Is there a vertical chimney cap designed for heavy snow, or do I need to use a horizontal vent cap? Thank you.
1 Answer
On Direct Vent unit you have the choice to either vent the unit vertically or horizontally. In a heavy snow area you will have to watch for high build up of snow on the roof which can also block the cap. Some units have a horizontal "snorkel termination" that also may help your situation.

I have a Morso air tight wood stove, with a 6" round vent that I want to connect to an existing 8" round vent. Is this a good idea?
1 Answer
It is never a good idea to use a larger diameter chimney system with a stove that has a smaller flue collar as it may very well lead to performance issues with the stove and creosote buildup in the chimney, but you would need a 6-8" increaser like the Snap-Lock Black Steel Stovepipe 6-Inch Male to 8-Inch Female Increaser.

I need to replace the plastic screen and cover on the outside brick wall for a fresh air vent for a fireplace. The existing broken cover fits inside a pipe that is 3.5 inches. The closest size I can find for a replacement is 4 inches. It would take masonry work to replace the 3.5 inch pipe with one that is 4 inches. Is there a solution or smaller size cover available?
1 Answer
Unfortunately, we do not offer replacement outside air kit covers that will work with 3.5" diameter flexible duct.

The correct venting kit for the Innsbrook series is the Empire DVKI-2P Innsbrook Direct Vent Gas Fireplace Vertical Vent Kit - 17 Foot. This will contain all items needed to properly vent the insert.

I have a wood burning fireplace that won't draw and smokes up the room. I want to go with a vented propane log set. Can I just put the log set in since I have an open flu?
1 Answer
Vented logs can indeed be installed in a wood burning fireplace and used with the damper open. However, the drafting issue should be corrected first. If the fireplace is not drawing in a wood burning application, it is unlikely to draw with gas logs either. This can lead to spillage of harmful carbon monoxide into the room. I recommend having a local chimney sweep or NFI technician out to evaluate the draft issue before moving forward.

I bought the Napoleon EP13 wood burning fireplace insert and I need to get flexible pipe to run out of an existing fireplace chimney that is about 15 foot long and something to attach it to the insert flue pipe opening and the flexible pipe. What do you recommend?
1 Answer
A flexible stainless liner kit, such as the DuraFlex 6 Inch Diameter x 15 Foot Long Kit of 304-Alloy Light Chimney Liner would be the best product to use. This will include the appliance adapter that is used to attach the liner to the flue collar of the insert, as well as the flexible liner, top support plate, and cap.

I am installing a DuraVent through the wall chimney system in a metal garage that is insulated and there is a 10" gutter on the outside that I would like to clear. What is the best way to mount the 'T' bracket another 10" away from the wall of the building? This would give me 2" of clearance past the gutter.
1 Answer
Rather than build out from the side of the home with lumber, what seems to work really well is to sink a pair of 4 x 4 treated wood posts into the ground and cut them just high enough for the tee support bracket to mount to. This offers a sturdy mount that does not compromise the appearance of the side of the home. You can then anchor the pipe to the eave as it passes it.

I am looking at the Osborn 2200 to put in my house that is under construction. What type of chimney assembly will I need to be code compliant in NC? The chimney will be vented through an empty attic space and out the pitched roof.
1 Answer
The manufacturer requires the use of single or double wall stovepipe within the room, then Class A chimney from the ceiling and on out through the roof. Some areas require that the Class A chimney be triple wall only and that the stovepipe in the room be double wall. I highly recommend consulting your local code office to verify.

I have a fireplace insert with co-linear (both 3-inch) venting. It is installed in a masonry fireplace. Recently, due to some damage, we had to tear down the top of the chimney. The fireplace is still in good shape, and I would just like to replace the masonry chimney above the roof line with a metal chimney. I need to buy a chimney pipe that meets code that I can run through the attic and out the roof. The chimney pipe would have to be able to fit the two three-inch flex vents. I would also need a high wind termination cap that can be mounted on the top of the new metal chimney. The whole set-up is vertical without no bends. The fireplace will never be used with wood again. What would you suggest?
1 Answer
The transition component needed to for your application would be the Dura-Vent DirectVent Pro Co-Linear Chimney System Top Termination Kit. Once the flexible 3 inch liners have been clamped into position and the top plate anchored, you can then connect the needed sections of 4 x 6 5/8 DirectVent Pro co axial piping.

We have installed your 42" builders fireplace and the contractor is not happy with the chimney cap. He feels that it does not sit deep enough into the pipe and he is afraid that it will allow rain to come down the pipe in severe weather.
Check my photos and let me know if the cap is installed correctly and whether you feel that rain will be able to enter the screened area at the bottom.
1 Answer
Looking at the close up photo of the cap mounted, the attachment brackets do appear to be sitting in place properly and the screened area height looks correct. The screened area does have to remain open for adequate cooling air to be drawn into the chimney. Product testing for this item has revealed that only a heavy driving rain will allow some water to make its way down the outer chimney jacket. Even in that case, the amount of water that does get in will not cause any damage.

I purchased an FMI Bungalow 36" wood burning fireplace. I also ordered the FSD-RLT-8DM round top. What do I need to close the top of the double wall pipe before I slide on the top?
1 Answer
No adaptor is needed to connect the RLT-8DM cap to the 8DM pipe length. Simply install the RLT-8DM cap directly on top of the last 8DM pipe length above the roof line at the proper height per code.

Hello,
We are renovating our fireplace and just demolished what was existing there. What we are left with is a galvanized pipe with terracotta insert. Can we reuse the galvanized pipe? the terracotta insert? We are on the first floor; the pipe goes through the second floor apartment above us. How do we go about with installing our new fireplace?
We would like a gas stove, something like the first photo I am submitting.
1 Answer
From the appearance, it looks as if this was originally a masonry chimney and fireplace. At some point, the chimney must have been deemed unstable and was demolished, with the galvanized pipe installed in place of what was there. Depending on the brand and size of the pipe, it may be possible to adapt a gas stove. If not, the entire vent system may need replacement. Please advise if you are able to find any manufacturer or model information stamped into the outer wall of the pipe.

I have a Squire stove insert and the opening on the stove should go from the 3" x 8" to an 8 inch round, but I can't find that part anywhere. Can you help me?
1 Answer
Unfortunately, oval to round adapters are indeed becoming increasingly difficult to find, as less stoves are seen that still use an oval opening. We carry a few generic oval adapters, but they do not fit your sizing requirements. It may be necessary to have a custom adapter fabricated by a local metal shop.

October 28, 2013
I have been doing a lot of research on the internet and it seems that there is no purpose for a fresh air side vent on the fireplace. It was an old myth that it helped keep smoke out of the house or stopped your fire from taking the air out of the room. Can you please enlighten me on this topic?
1 Answer
A fresh air kit is definitely not intended to prevent smoke rollout. Smoking is a symptom of an improper chimney setup or air leaks in the ceiling of the home and an outside air kit will do nothing to remedy this issue.
However, the kits do a good job of supplying makeup air to the room in a tightly built home. Open faced fireplaces do pull a great deal of dilution air out of the room. In older homes with lots of gaps in the outer envelope, fresh air would pull through the gaps and replace the lost air. This is why some fireplaces would make every room in the home, except for the one the fireplace was located in, feel cooler.
A newer home will be tightly sealed and the fireplace will have no place to pull combustion air from after it has been used up from the house. When open, the combustion air vent will allow outside air to pull in toward the fire and sustain it. Some air vents are designed better than others, so the actually difference they make can vary.

I have a Vermont Casting Intrepid with 6 inch round pipe at the stove. I need to go through an opening, then up about 18 feet on the outside. I have vinyl siding and do not want to build a chimney around the pipe. I do not want to be looking at a rusty pipe in a few years either. What can I do to avoid this?

For best protection against corrosion, insulated stainless steel class A chimney should be used.

from Nashville, TN asked:
October 2, 2013
We are building a house and want a gas fireplace. What are our options for not incurring the expense of a chimney? I am leaning toward direct vent (not vent-less, read too many negatives). The room is on an outside wall but the fireplace will be positioned on wall adjacent to a 2-car garage. Also, if we vent vertically, are there specifications on how tall the vent pipe must be once it extends outside of the roof?
1 Answer
A direct vent fireplace will indeed offer the best versatility for running the vent piping and will have no negative effect on indoor air quality. Direct vent piping can extend as little as 12 inches above the roof line, but it depends primarily on the pitch of the roof the pipe will be protruding through. It is also possible to vent horizontally into the adjacent space and enclose the vent pipe in a sheet rock chase to hide it, if you do not want the chase in the same room.

No matter the reason you chose to install a stove or fireplace insert, it is crucial that you perform regular maintenance to ensure that it continues to function efficiently. Different types of fireplaces will require unique cleaning processes and products. Read on to educate yourself on how to maintain the one that you have chosen! One of the primary issues that you should address with your wood-burning stove is the buildup of creosote in your chimney. Creosote is a sticky residue that adheres to the inside of your firebox and chimney, and it is associated with a higher rate of air pollution in the output of your fire. This phenomenon is usually caused by using wet firewood or firewood with a high concentration of resin (such as pine), though there are other causes as well. See this article for more information on creosote buildup and cleaning: Why and How to Minimize Creosote Buildup in your Chimney. If you are dealing with first or second stage creosote, check out our chimney brushes and cleaners to find what you need to take care of the mess! Although maintaining pellet and gas-powered stoves is much simpler than the wood-burning variety, consistency is the key to keeping it simple. It is recommended that you perform an in-depth inspection annually; and unless you are very familiar with the parts and operation, it is a good idea to hire a professional to do this job. In addition, you should regularly empty the fire box and clear out any dust or soot; also, make sure that the door is secure to avoid leaking carbon monoxide into your home. Check out these two article for more information! Steps to Maintaining a Pellet-burning Stove and How To Keep Your Gas Fireplace Clean.
