If I order a 40 x 16 Multi-flue semi-custom Gelco chimney cap with a 4 inch overhand, does that mean that the top will be 48 x 24 inches?
By Will M. on August 25, 2015
Answer:Yes, the screen size would be 40" x 16" and the lid would be 4" larger on all sides.

How is this product installed?
By eFireplaceStore on October 21, 2014
Answer:There are a couple of ways to install this type of cap. The first is to test fit the cap to determine proper placement, then using construction adhesive, apply a bead to the metal swing tabs that run around the perimeter of the cap. Then, firmly secure the cap to the chimney wash.
The second way is better for removal. Test fit the cap on the chimney wash and once the correct location is determined, use a marker to mark mounting points around the perimeter of the swing tabs. You should have 2 mounting points on each long side and 1 on each short side. Set the cap aside and use a masonry drill bit to drill at your marked attachment points. Insert concrete anchors appropriate to the size of the holes you drilled. Lastly, place the cap in position and install fasteners through the tabs into the anchors.

If I choose installation option two of this Multi-Flue Gelco chimney cap, and mount it to the chimney wash, how far past the flue should I measure? For instance, if the two flues together are exactly 12 3/4" x 21", what size cap should I get?
By Chris C. on May 26, 2015
Answer:With the mounting strip being .5" wide, I would allow for at least 1" between the outside of the flue tile to the inside of the screen at a minimum, but additional coverage is ideal. With the two flues measuring 12.75" x 21", I would choose a cap no smaller than 15" x 23", but no greater of course than the outside measurement of the chimney wash itself.

I have a chimney crown that measures 21 1/4 x 50 1/4 What is the right size for me?
By Will M. on January 26, 2016
Answer:To select the right size cap for your chimney, you would need to select a size that is larger than the outside dimensions of your flue tile yet smaller than the outside dimension of your chimney crown. For the mesh height, you will need to select a height that is at least 5" above the tallest flue tile extending from your crown. However, you have a single flue chimney and we may be able to locate a more appropriate cap with both the inner and outer dimensions and shape of the flue.

Is there a flange on the base of this Multi-flue Gelco chimney cap to anchor to a flat base and not the flue?
By eFireplaceStore on June 30, 2015
Answer:There is indeed a perimeter swing tab system that allows you to anchor this cap to the concrete crown of your chimney. The tabs can be swung inward or outward of the mesh walls, in order for the best fit for your application.

Is there any disadvantage to using a higher screen mesh than required? Would more clearance above the flue result in a better draft?
By eFireplaceStore on November 28, 2016
Answer:A taller mesh will indeed result in less draft impedance, however there is a compromise that needs to be made between draft and flue protection. I recommend leaving no more than 8 inches of space between the top of the flue and the underside of the lid for proper coverage.

I am looking at this Multi-Flue Semi-custom Gelco chimney cap to go over two flues that extend approximately 2- 3 inches above the chimney crown. What I am unsure about is how high the cap should be. You have several options where the heights are different, and I do not know what height I should get. How do I determine this?

The outside dimensions of my chimney flue are 18 1/4 x 13 1/4 inches. Would I need to order a 19 x 14 inch chimney cap to fit?
By eFireplaceStore on October 12, 2015
Answer:A 19 x 14 cap will indeed work for your application, as the measurements for these caps are taken from the interior of the screen mesh.

How do I measure my chimney for a chimney cap? Do I measure the perimeter of the brick lining?

I want to secure this Multi-Flue semi-custom Gelco chimney cap using the center of the mortar joints on the top surface of my chimney. The center measurements are 12 1/2" X 23 1/2". Can 1/2" measurements be produced and how much should I allow for the flaps to affix to the chimney? Can I get away with 12" X 23"?
By Will M. on October 6, 2015
Answer:This cap mounts to the surface of the chimney crown in between the outer diameter of the crown and the outer diameter of the terracotta flue that protrudes from your chimney. Subsequently, you should choose a size that is slightly smaller that the outer diameter of the chimney crown, but larger than the outer diameter of the terracotta flue. The base has 3/4" swing tabs that can be either inside or outside mounted.
