Two important things to note!

  • If you are using an inside mount cowl on a tile flue, caulk it into place with silicone sealant.
  • If you are using an inside mount cowl on a metal flue, do not use the sealant.

Metal chimney flues get too hot and can damage the sealant. For a cowl that attaches to the chimney, plan the spacing of the masonry anchors before attaching the cap.

Use an anchor on each side of the chimney. Keep the anchors at least one foot apart. Slide the chimney cowl flange onto the crown of the chimney. Then straighten it using the level.

Follow all provided directions for application. If the cowl must be screwed on, hold the cowl flange tight against the masonry and drill through both at once. Sink the masonry anchor, then insert the first screw into the bracket and tighten it into place.

Drill the next hole on the same side as the first. Use the level and work around the perimeter of the chimney, tightening consecutive screws as you proceed.
