For a multi-cap chimney, would I need to measure the length, width, and height of flues?
By Collin C. - NFI Master Hearth Professional on October 8, 2013
Answer:Precisely. The outside dimensions of the flues, as well as their projection above the chimney wash would need to be known. Any offset from one flue to the other will also need to be noted.

How can I keep water from going down my chimney? What kind of chimney cap should I use?
By Collin C. - NFI Master Hearth Professional on July 29, 2013
Answer:Generally, the best way to stop this from happening is to use a chimney cap that is oversized to the chimney opening.

Would getting a cap with damper help with my very old stone fireplace with a rusted out damper? The draw up is not good and smoke rolls back into the room.
By Collin C. - NFI Master Hearth Professional on July 29, 2013
Answer:Likely not. A poorly drafting fireplace is usually caused by one of the following problems:
1. Chimney flue is poorly insulated (cold hearth syndrome).
2. Chimney flue is too large for the opening.
3. Chimney is too short.
4. Obstruction near the chimney is interfering with drafting.
5. Prevailing wind is overpowering natural draft.

Is there such a thing as a cap extension? Our two crocks are jammed together. We have a cap over them but need it raised higher.

My house was built in 1967. I have a natural wood fireplace with a single flue. We want to convert to natural gas with vented logs. We want to preserve as much heat as possible and not have it all go up the chimney. Can you give us some advice on how to do this?
By Collin C. - NFI Master Hearth Professional on October 16, 2013
Answer:Vented logs by nature give a great deal of their heat up to the chimney. The best way to preserve some heat is to regulate the damper assembly in the fireplace. If the cast iron damper is intact, it can be closed down far enough that the log set damper clamp is the only thing keeping it propped open. This will help to keep hot gases in the smoke chamber longer, increasing heat output.

We have a wood stove and rain comes down the chimney pipe when it rains at an angle. There's an 8 inch pipe inside of the larger pipe and I think the rain is coming in the space between the two pipes. Is there some sort of a cover or flange that will cover this gap? The outside pipe is approximately 44.5 inches in circumference, with a 14" diameter.

I get lousy draw in my fireplace when the cap is on. What is wrong?
By Collin C. - NFI Master Hearth Professional on July 15, 2013
Answer:It is quite likely that the draft of your fireplace is weak to begin with and the cap is simply enough to stifle what little draft there is. There are a couple of things that could cause this. 1. The chimney cap screen height is too short, placing the top of the cap too close to your chimney termination and impeding draft. 2. The chimney is too short and the house itself is fighting the chimney for draft. This often is characterized by smoke rolling back into the room.

I want to purchase and install a chimney cap but I currently have a round cap at the top of the chimney liner. This round cap does not cover the square chimney pipe. What should I do? By the way, my furnace no longer uses the chimney, just the hot water tank.
By Collin C. - NFI Master Hearth Professional on October 23, 2012
Answer:Do you happen to know how the liner is currently supported at the top of the chimney? If it uses a flat metal support plate, and the liner is clamped to the plate, you should be able to remove the current cap and storm collar, then cover the square clay flue tile with a larger cap.
However, if the liner is the type that attaches to your current cap, then pulls down on the top plate, you will need to support the liner using alternate means. It is possible to use HVAC strapping to hold the liner in position, then attach another cap.

When it rains, water seeps down and through the mortar between the blocks. Can I do anything to prevent this? Is getting a chimney cap my best option?

I have an air insulated class A chimney pipe that needs a new cap. The current one seems to allow water into the stove. How should I measure the size cap required? Is it the inside diameter of the current pipe?
By Tyler M. - NFI Certified Specialist on July 16, 2013
Answer:Yes, please measure the inside diameter of your pipe. Being able to identify the manufacturer/model information of the pipe will also be helpful, if you want a factory replacement.
By Heather from Gainesville, Georgia on January 14, 2013
We are looking for a "fireproof" product or material to place on top of our chimney cap to hopefully get rid of noise. We have a 2 story home with a fireplace containing gas logs on each floor. The second floor fireplace is in our master bedroom & unfortunately we have a hickory nut tree that drops nuts on top of our stainless chimney cap, thus making a lot of noise. Rain is also a noisy factor due to the cap being 12 feet away from our bedroom ceiling and our home being located on the highest elevation on the lake in our state, we see a lot of heavy storms/wind making a lot of noise. Do you know of any "fixes" or products available?
By Collin C. - NFI Master Hearth Professional on January 15, 2013
Answer:Unfortunately, I do not have an insulating material that can be applied to a chimney cap that with withstand both the heat and outdoor elements. The main thing I can suggest would be to cut several pieces of sheet metal to the same size as the cap lid and either rivet or screw them to the lid. By adding layers of metal, this will increase the overall thickness of the lid and will cut down on reverberation. Applying a thin layer of construction adhesive between the layers of metal would further insulate the noise. I apologize that I do not have a premade product to remedy this issue.

I need a chimney cap. I have a problem with bees. Do they make a chimney cap with mesh small enough to keep the bees out?
By Collin C. - NFI Master Hearth Professional on February 25, 2013
Answer:For instances when small insects are a nuisance, I recommend wrapping the factory chimney mesh with a smaller gauge stainless steel wire mesh. So as not to impede draft, I do not recommend going smaller than 1/8 of an inch.

What are the pros and cons of single chimney caps vs. one cap that covers both flues?
on November 9, 2012
Answer:The main advantages to a single cap are a cleaner look and generally lower cost overall. It will also eliminate the need for determining the proper lid size needed for the side by side flues. However, a single cap can cause back drafting issues, if the flues are close to each other. Individual caps, especially if they are staggered in height, will help to avoid the individual flues pulling against one another. Obviously, there must be enough clearance between the caps so that they do not bump one another.
Please let me know if I can assist you further.

I am looking for a 17" x 22" chimney cap preferably that has a tightening band used to attach it to chimney. What options do you have available?
on November 9, 2012
Please view the cap at the link below. It has an outside perimeter band as you describe and can adjust between 16.5" to 18.5" on one side and 20.5" to 22.5" on the other. This should suit your needs accordingly.
Please let me know if you have any technical questions about the product or if I can help you in any other way.
By Pete on November 9, 2012
I have a double flue, each about 18 x 18. I use a vent free gas log set. I would like a flat cap on each flue. We live on a high ridge with a lot of wind. Is all is right if we get rain in the flues, even though the total stack has a concrete cover? Bottom line: we don't need the wire, just a means to tighten down a cover. Do you have any ideas?
on November 9, 2012
Answer:Given the fact that a vent free log set does put off some residual heat to the chimney, I would recommend using a wind/rain guard on the side of the chimney that is exposed to the prevailing wind the most. This way, the chimney will still be able to vent properly, but will be less susceptible to water intrusion. Unfortunately, this would be somewhat of a custom application, as we really do not carry anything that can be used on larger chimneys as a wind guard. You would likely need to have a guard manufactured by a fabricator out of 22 gauge stainless steel. Unfortunately, we do not offer any fabrication. We are a dealer of finished products only.

What is the lowest cost for an 8" high cap that will fit my brick chimney with an outside diameter of 17.75" X 27"?
on November 9, 2012
Answer:Unfortunately, I do not have a cap in these exact dimensions. However, I do have caps that are slightly smaller and can be attached to the top of the chimney, rather than around the outer perimeter.
By Paul from Trenton, Ontario on November 4, 2012
I have a 5-inch liner inside an 8 inch x 12 inch clay flue tile. Can you please advise products that will fit this application? I prefer copper.
By Collin C. - NFI Master Hearth Professional on November 5, 2012
As far as capping the 8 x 12 flue tile goes, the Gelco 8 in. x 13 in.
cap could be adjusted to work. However, I am unsure of how your 5-inch liner is currently supported. It is possible to attach this cap over an existing top plate, if that is what you currently have.
Also, the supplier of this cap will not ship to Canada, but we could ship to a U.S. location for shipment forwarding of the cap.

I purchased 6" double wall Super-Vent chimney pipe and I need to purchase a chimney cap. Is a Super-Vent cap the only brand that will work with this pipe?
By Collin C. - NFI Master Hearth Professional on November 26, 2012
Any push-in type of 6 inch cap for factory built chimneys will work. Selkirk's SuperPro line also uses the same type of twist lock mechanism as their Supervent line. As such, this SuperPro All-Fuel Deluxe Chimney Rain Cap
would offer a direct fit to your existing chimney and would give a factory appearance.
By Dona from Searcy, AR on November 4, 2012
I have a double-wall solid pack insulated round chimney pipe. The interior pipe is 6". Exterior is 9". My present chimney cap has the interior pipe and then an exterior wall that fits over the outside pipe. The stove is installed in the front, on a very steep roof that is a single story in the front and two story in the back.
I need a replacement but am not sure exactly what to get. The company that installed the stove is out of business and there is nothing to tell me the brand of the original cap (22 years old).
