Do the dimensions include the tabs used for mounting?
1 Answer
No, the dimensions are based on the screen-to-screen size. The 3/4" mounting strips can either flip inside the screens or outside the screens for mounting to the surface/crown of the chimney around the flue(s).

If I select a 14" width (inside), what will the outside dimension required on the chimney?
1 Answer
This cap is a surface-mount, meaning it does not attach to the outside of the chimney. The width and length you select will be the screen-to-screen size of the cap, and then there will be a mounting flange that can flip inside or outside the screens, and you can then use masonry anchors plus adhesive (optional) to attach it to the chimney.

How does the Gelco Model # 0909M8 cap attach to the clay flue pipe?
1 Answer
No that cap mounts on to the crown of the chimney. The size not only depends on the flue opening/pipe size, but the OD of the chimney itself.

You had a similar question to this one, but the answer didn't match what I think is logical. I have a 23 by 19 old chimney (no flue), so I would like the cap to set over the chimney and bolt on top of it. Is this feasible? And would I add inches to the dimensions?
1 Answer
This is absolutely feasible. Note that the caps we offer are listed by their screen-to-screen size. So, for your application, if 23" x 19" is the outside dimension of your chimney, you would want to size down an inch or two to allow room to mount the swing-tabs to the top of your chimney.

I have a brick chimney; do I measure the outside diameter of the brick opening exactly or add extra an inch?
1 Answer
Since that cap mounts on the crown, you would need to measure both the flue opening and the OD of the brick chimney as well.

I'm a DIY'er and just finished putting a crown on our chimney. I'm not sure how tall the screen height of the cap should be. It's a 2-sided fire place, ranch style house. I'm thinking of centering the cap on the crown using a 16" x 35". Any thoughts? Pictures attached.
1 Answer
With these caps, you should choose a screen height at least 5" taller than the tallest flue tile extending from the crown surface.

How much do the mounting flanges add to the length and width of this Multi-flue semi-custom Gelco chimney cap? Also, how do I remove the cap for cleaning? Remove the tapcons?
1 Answer
The cap will arrive with 3/4" reversible swing tabs at the base for securing the cap to the crown via inside or outside mounting, depending on preference. This is not removed for cleaning and will stay secured to the crown. For cleaning, the lid can be quickly removed by unbolting the cap screws that hold it in place.

Does it matter which side is Length and which side is Width?
1 Answer
It does not. However, just so we have a reference between the two, there are longer lengths available than widths. The industry standard defaults the length as being greater than the width.
