When trying to determine which chimney cap is best for the job, you must consider the configuration of the chimney, and any flue(s) in it.

 

For example, a multi-flue chimney cap would look much nicer on the picture shown at right than a small, single flue cap on the photo at right. In this scenario, either would fit and either would help protect the chimney against rain, birds and animals - but a larger multi flue cap with a base size closely matching the chimney casing measurement would best compliment the architecture of the home.

 

 

 

Single Flue Chimney Caps

Single Flue Chimney Caps are most often used for a masonry chimney containing a single flue (the opening in the chimney) and when there is a raised tile liner that extends above the mortar crown.

 

Measure the length and width of the OUTSIDE of the clay tile liner:

 

Width = _____________  Length = ____________

 

Single flue styles are adjustable within a couple of inches on each side because they are attached with slotted hex bolts that offer some installation flexibility.

 

 

Multi Flue Chimney Caps

A multi-flue chimney cap attaches to the mortar crown surrounding your flue tile liners. This style is best if

 

• the flue tile liner does not extend more than 2" above the chimney mortar crown
• there is more than one flue in the chimney
• the chimney flue us unlined.

 

Our "stock custom" multi-flue chimney caps offer a 47 stock sizes, with 4 screen heights.

The caps are sized by the "screen-to-screen" size; screen to screen size must exceed the opening(s) of your flues.

**The mounting flanges extend 1-1/2" on each side of the cap, so make sure your "C" and "D" measurements allow adequate space for these mounting flanges.
