In summary, a stainless steel chimney chase cover fits over the top outside edge of your chase or brick chimney, similar to a shoe box top. It can have no holes, one hole, or multiple holes, and is custom fitted to your particular chimney or chase. Here's how to measure for a great fit:

Length and Width:

When measuring for a custom fitted chase cover, it is important that all measurements are accurate to the nearest 1/8". In addition, be sure to measure all four sides. Just because one side appears to be the same length as the other does not mean it is! Mortar joints in between the bricks may be slightly different sizes, causing uneven side lengths, for example.

Measure both long sides and use the longest measurement for the length. Secondly, measure both short sides and use the longest measurement for the width. In summary, 1/4" should be added to both length and width to provide the necessary tolerance for fabricating your chase cover.

Hole Measurements:

If you need a hole(s) for your flue pipe to come through the chase cover, you should measure the round pipe diameter and add 1/2". For oval/square/rectangle clay flues, add 1/2" to each dimension.

Please note, this extra allowance is important. If the hole is too small, your pipe will not fit through the chase cover. Moreover, the gap between the metal pipe and hole can be covered with an optional storm collar or sealed with a sealer (for clay tile).

Lastly, be sure to include the dimensions to the edge of each hole from all four sides of the chase cover, so that the hole can be placed correctly. If you want the hole to be centered, then no additional dimensions are needed.

Collar Height:

Typically, the standard collar is 2" to 3". In addition, the collar is rolled out with an overlap, spot welded, and siliconed for extra protection. For a square or rectangle hole that will have a clay tile flue liner protruding from it, you may want to make the collar the same height as the clay tile in order to install a single flue chimney cap.

Skirt Length:

The skirt length should be long enough to cover any exposed wood and allow fasteners to go through the skirt and into the structure behind it for security. The standard skirt lengths are around 3".

Drip Edge and Diagonal Creases:

Two important, no charge options are the top diagonal creases and the 1/2" drip edge, added to the bottom of the skirt. Firstly, the creases prevent water and snow from accumulating. Secondly, the drip edges keep the water from falling directly onto your siding or brick. In conclusion, only the length, width and number of holes determine the price of the cover.

Stainless Steel Chase Cover Storm Collar

Storm Collar:

Most importantly, the storm collar prevents water from entering the chimney between the metal pipe & the chase cover hole. Firstly, measure the outside diameter of the pipe. Lastly, use the chart below to select your storm collar size.
