Geez, I think I need a "Fireplace for Dummies" book!š¤¦š»āāļø I appreciate as many of your comments as possible because I'm definitely out of my element here.
Question for StoveLiker
StoveLiker, when you said, "It might have saved your home in the fire, and that's what they're meant to do," I didn't quite catch what you meant. Are you referring to the cap's function or something else?
Dent in Cap
The cap has a dent (see photo), which has been there since installation. Could this dent interfere with its ability to adequately vent smoke by disrupting the airflow or draft?
Manufacturer-Approved Cap?
This is a Majestic Biltmore 42 fireplace. Do I need to stick with a cap recommended by the manufacturer, or if I can consider other types of caps? If so, any suggestions for alternatives?
Makeup Air Compensation by Open Windows?
We know that a makeup air system would be needed to prevent backdraft when the windows are closed. However, here's where I'm confused:
Even with two 7-foot casement windows (open about 4 inches each), a little smoke still escapes at the top of the fireplace. Shouldn't having the windows open compensate for the lack of a makeup air system? And if so, does this indicate that we might have an issue with the chimney draft?
Should We Extend the Chimney Height?
The manufacturer's manual specifies a minimum chimney height of 18.5 feet from the base of the fireplace unit to the top of the cap (ours measures 20 feet). And, in case it's relevant, the actual chimney section is 17.5 feet from the damper,(NOT including the 9-inch cap).
The installation manual states that the 'chimney height may need adjustment if smoking or overdraft occurs.'
Would extending the chimney height in 2-foot increments be worth a shot to improve the draft?
Thanks again for all of your comments!
