Section 402.4.3 of the 2009 IECC requires new wood burning fire places to have gasket door and outside combustion air.

Several mason have asked me if a Lyemance chimney top damper instead,

There are several other similar “energy effect” dampers available

While the 2012 IECC sections 402.4.2 allows tight fitting flue dampers.

Discussion;

1) Is a chimney top damper a tight fitting flue damper?

2) Would those that are enforcing the 2009 IECC allow the top damper

3) If one was using a top damper have there been problems with warm moist air condensing in the chimney flue?

4) Other comments…

1- Is a chimney top damper a tight fitting flue damper?

Regardless if it is or not, it is NOT a gasketed door as required.

2- Would those that are enforcing the 2009 IECC allow the top damper

In lieu of gasketed doors? NO

3- No
