I've been running the 1500 (Hor discharge, with a damper, tee, and 15' vertical flue) since Sept without incident. I had a situation today that I wanted to share. I have a dedicated boiler building with two separately insulated rooms connected by an inside door - one 10x20 for the boiler and one 10x20 for wood storage. I just topped up the wood storage area and I raised the humidity level in the entire building due to some snow and frost on the wood. When it drops below zero I tend to get a layer of frost on the Garn intake pipe, but not as much as last night due to the increased moisture in the building. I only have to do a single fire down to about zero, but last night it was about -15 so I ended up with an extra burn this morning. When firing the beast tonight the fan wouldn't kick and I had a damper failure error on the screen. The damper is located near the outside wall and was frozen up tight. With just a single burn I may have had time to melt things back there, but I've got a double layer or Roxol on everything so the building only stays about 55 when it's below zero and not much more.............. The good news is that I left 3 feet behind the boiler to allow access back there. The second good news is that Heaterman gave me the suggestion to drop a couple electric baseboards in the boiler room in case I went away and wanted some freeze protection out there. Here is the heads up..... If you're planning a layout and use a damper if going with a vertical discharge...........leave room back there to get at stuff ........that, plus the baseboard heater back there made an ugly thing a piece of cake. Thanks Steve!!
