Single Flue Chimney Cap Measure Guide

 

Single flue caps attach to the flue. For chimneys with a single square or rectangular flue, select a chimney cap like those shown below. Some single flue chimney caps that attach to the flue with clamps. The majority of single flue chimney caps, however, attach to the flue with set screws that press against the flue.

Here are examples of chimney caps for single flues that attach to the outside of the flue with screws:

What to Measure for a Single Flue Chimney Cap

To measure for a single flue chimney cap, measure the outside length and width of your flue.

What to Measure for a Single Flue Chimney Cap If the Flue Does Not Stick Up at Least an Inch

If your single flue does not stick up at least one inch, you can use either a top mount chimney cap (also known as a multi-flue chimney cap) or a single flue chimney cap with a set of “legs.” The legs fit down inside the chimney flue and securely hold your chimney cap in most situations. We do not recommend the use of chimney caps with legs especially in areas with high winds. A top mount chimney cap is always a more secure choice if your single flue does not stick up at least an inch.

Single Flue Chimney Caps with Legs

•     If your flue does not stick up at least one inch and you want a chimney cap with legs, measure the outside length and width of your flue.

•     If your flue does not stick up at least one inch and you want a chimney cap that mounts to the top crown on your chimney, follow the measuring directions for top mount chimney caps (also known as multi-flue chimney caps.)

Which Metal is Best for a Single Flue Chimney Cap?

Single Flue chimney caps are manufactured from stainless steel, copper, and galvanized steel.

•     Stainless steel is the best value for the dollar. Stainless steel is the preferred metal for salt water climates.

•     Copper is the most elegant, especially for historic or upscale homes. Copper is not recommended for light colored chimneys.

•     Galvanized steel is the least expensive and the least durable.

Stainless steel and copper chimney caps come with a lifetime warranty. Some stainless steel caps can be powder coated with black or colored with heat resistant finishes. Galvanized steel chimney caps are painted black.

Round Double Wall Flues

Below is a flue that is a cut-away illustration of a Double Walled Air Insulated Flue or a Double Walled Air Cooled Flue.

Double Walled FlueA Double Wall Air Cooled flue is also known as an Double Wall Air Insulated flue. These have one pipe inside another. Air circulates in the open space between the two pipes to cool the flue. This type of flue requires a round flue chimney cap specially designed to allow the air circulation that is needed.

 What to Measure: Measure the inside diameter of the innermost pipe and the outside Bottom Collar and Inner Diameter of Innermost Fluediameter of the outermost pipe; the bottom collar of the chimney cap should be large enough to cover the outermost pipe.

Select a round flue chimney cap that is nominally the same diameter as your innermost pipe. (Example: a 6 inch flue uses a 6 inch Weathershield or Vacu-Stack chimney cap). The bottom collar (indicated by the red arrows in the diagram to the right) of the chimney cap should be large enough to cover the outermost pipe of your chimney.

Round Flue Chimney Cap Guide for Covered Insulation FlueInsulation within the flue distinguishes a Solid Pack flue, also called a Double Wall Insulated or Solid Packed Insulated flue.
In many, the actual insulation in covered, as shown in the cut-away illustration to the left, and, therefore, not visible as you look down into your flue.

What to Measure: Measure the inside diameter of the innermost pipe(the flue).  Select a chimney cap that is nominally the same diameter as your flue. (example: a 6 inch flue uses a 6 inch Weathershield, Homesaver Pro, or Vacu-Stack chimney cap).

 

Exposed Insulation Solid Pack Round Flues

Below is a cut-away illustration of an Exposed Insulation Solid Pack Flue.

Round Flue Chimney Cap Guide for Exposed Insulation FluesCan you actually see insulation between the two concentric pipes of your flue? Then you have an Exposed Insulation Solid Pack flue. Some chimney caps for double or triple walled air-cooled chimney caps will work for Exposed Insulation Solid Pack flues.

What to Measure: Measure the inside diameter of the innermost pipe (the flue).  Select a round flue chimney cap that is nominally the same diameter as your Exposed Insulation Solid Pack’s innermost pipe.VacuStack for Exposed Insulation

 

Triple Wall Air Cooled Round Flues

Below is a cut-away illustration of a Triple Wall Air Insulated Flue , also known as a Triple Wall Air Cooled Flue.

Round Flue Chimney Cap Guide for Triple Walled Flue
Triple Wall Air Insulated flues have three concentric pipes. Cooling air circulates in the open spaces both between the outermost and middle pipe and between the middle pipe and innermost pipe. This type of flue requires a chimney cap that can circulate air between the flues to cool them.

 

What to Measure: Measure the inside diameter of the innermost pipe and the outside Bottom Collar and Inner Diameter of Innermost Fluediameter of the outermost pipe; the bottom collar of the chimney cap should be large enough to cover the outermost pipe.

Select a round flue chimney cap that is nominally the same diameter as your innermost pipe. (Example: a 6 inch flue uses a 6 inch Weathershield or Vacu-Stack chimney cap). The bottom collar (indicated by the red arrows in the diagram to the right) of the chimney cap should be large enough to cover the outermost pipe of your chimney.

Stop Fireplace Grate Melt Down

How to Prevent Fireplace Grate Melt Down or Burn Through

Does your fireplace grate look like the one above? Has it burned through in the center? Find out what causes fireplace grate melt down and learn how to make your fireplace grate last longer. Put an end to grate burn-through.

What Causes Fireplace Grate Melt Down?

Heat will oxidize (rust) any metal made with iron. That includes cast iron and steel. Over time, heating your grate again and again will cause the rusting process to thin the metal to the point that it bends or even severs.

How to Make Your Fireplace Grate Last Longer

However, there are things you can do to prevent fireplace grate melt down and make your grate last longer.

1.  After the fire goes out, remove the ashes that accumulate under the grate.
When burning coals fall through your grate and land upon a deep bed of ashes, the coals remain close to your grate instead of falling to the floor of the firebox. Hot coals increase oxidation, especially if they are touching the grate.

In addition, cool air should enter the firebox under the grate and rise to provide oxygen to the burning wood. However, a deep accumulation of ashes under the grate disrupts that necessary draft of oxygen. A fireplace with a good draft also generates less ash than a fireplace whose air flow is choked off by ash build-up.

Removing ashes after every use of your fireplace is the single best thing you can do to prevent fireplace grate melt down and extend the useful life of your fireplace grate. See what to do with those ashes.

2.  Try to move at least some of the heat away from the center of the grate.
Grates almost always fail in the middle because heat is concentrated there and because many grates are not well supported in the center. By distributing firewood and coals over the entire width of the grate, rather than moving them towards the center, you will help prevent fireplace grate melt down and prolong the life of your grate.

3.  Don’t douse your fireplace fire with water.
You may remember from Smoky the Bear or scout training to put out a campfire by stirring the embers and pouring water on the fire. That works for campfires, but the water can rust a fireplace grate. Banking your fire is the best solution. If you must put the fire out, stir the embers and add sand to extinguish your fireplace fire.

4.  Buy a cast iron grate rather than a grate made with welded steel bars.
Cast iron withstands heat better than steel does. Steel begins to soften and bend at about 1000 degrees Fahrenheit, while it takes about
1400 degrees to soften cast iron. Oak, the wood most often used in fireplaces, can reach temperatures near 1000 degrees when burning briskly.

5.  Buy a grate with the thickest material you can afford.
It just stands to reason it takes longer for a thick piece of metal to rust away than
it takes for a thinner piece. A grate made with 1” by 1” steel bar has four times as much metal as a grate made with 1/2” steel bar.

Compare the 3/4 inch bar stock on the left with the 1 1/8 inch by 13/16 inch bars on the grate on the right:

6. Get a fireplace grate with a Lifetime Warranty.
When you purchase a grate that you know the manufacturer will stand behind, you can have peace of mind. The Pilgrim brand of fireplace grates, for example, have a Lifetime Warranty against burn-through. The Pilgrim Lifetime Warranty provides one replacement grate if yours fails. The Pilgrim fireplace grates below have Lifetime Warranties:

Buying a cast iron grate or a steel grate with the thick bars and a Lifetime Warranty is the best way to get off to a good start for an enduring fireplace grate. Distributing the heat and properly tending ashes will definitely prolong the life of your fireplace grate.

Wine Cork Fire Starters

Wine Cork Fire Starters - How to make cork fire starters.

For many, a blazing fireplace and a glass of wine are a companionable duo.  But first, that bottle of wine needs to be opened and that fire needs to be started. Perhaps it speaks to the appropriateness of their pairing that the corks from the wine bottles can be easily turned into wine cork fire starters for your fireplace.

How to Make Wine Cork Fire Starters

The only tricky part of this do-it-yourself project is to be sure you are collecting wine corks that are actually natural cork instead of synthetic cork. The synthetic wine corks are made from plastic compounds to have a similar look and “pop” of real cork. But burning plastics in your fireplace can give off toxic fumes. Therefore, stick with natural corks.

Use natural cork for cork fire starters. Avoid synthetic corks for cork fire starters.

Process 

  1. Fill clean glass canning jars with natural corks. (You can use other recycled jars with lids as well. Just select jars with tight fitting lids.)
  2. Pour rubbing alcohol into the jars all the way to the very top. The corks will absorb the alcohol over time, so fill ‘er up! As you use the fire starters, you may need to add more alcohol to the jar from time to time.
  3. Seal the jars. Tighten down on them because you don’t want any of the alcohol to evaporate.
  4. Set the jars aside for a while.
  5. Wrap raffia around the lids for an added touch.

  6. Download Fire Starter Labels, cut them out, and attach them to the jars of cork fire starters.

How to Use Your Home Made Cork Fire Starters

Allow time for the corks to absorb the alcohol. When the clear alcohol begins to take on the mellow color of the corks, your wine cork fire starters are ready to use.

They are ready to use when the alcohol darkens.

They are ready to use when the alcohol darkens.

If you are making these for presents, make them 6 to 8 weeks before you gift them. (And they do make great hostess gifts or inexpensive but thoughtful winter holiday presents for friends, family and neighbors, particularly if you have decorated the jars with raffia and labels.)

When you want to light a fire, open the jar. Add one to three cork fire starters, depending on the size of your fireplace and grate, to the pile of tender, newspaper and logs. Re-seal the jar to prevent the alcohol from evaporating from the remaining cork fire starters. Light the newspaper, sit back, and enjoy your fire with a glass of wine in hand. And, yes, remember to save the cork from that wine bottle!
