Hello gang, it's nice to see the board coming back to life now that cold weather is here!
I got the Harman insert going a while back for the year and ran into an interesting problem. I am getting random chirps from my smoke detector. I've replaced the batteries can't figure out what could be causing the chirps. I read the back of the carbon monoxide detector and found out that they have a shelf life and that mine is three years old, could it need replacement already?
The insert is a Harman Magana Fire that was professionally installed and has a great draft and I checked the tightness of the door gaskets with a dollar bill all the way around the doors before the first fire and although the gaskets are starting to flatten out, I could not pull the dollar out anywhere around the doors. We had to leave for the holiday and the fire had gone out by the time I returned; yesterday when I was restarting the fire and the stove was coming up to temp I noticed a odor of burning coal so I pulled the surround panel off and checked the flue pipe to stove connection and it looked secure at the joint and the sealant at the joint was all there with no cracks. As the stove came up to operating temp (350° or so) the smell went away. The stove has never been over-fired (it's always been run below 450°) and the only possible way that I can see for any gasses to escape the fire box is through a 3" "plug" in the heat exchanger that must have been used in the manufacturing process that appears to be pressed in and not welded.
Anybody have any ideas or can think of something that I may have overlooked?
