I'll briefly explain what I've got here and the issue I'm having. I have included a ton of pictures to help show the system I have, etc. Sorry I can't get further away from it, there's a wall in the way. I decided to resurrect my Energy Mate wood furnace this year. It pipes into my normal furnace, and the furnace blower is supposed to blow the hot air through the house. It hasn't been used in 10 years or more according to the previous owners of the house. I cleaned the chimney, repiped the system, and cut all new firebrick for it, re-gasketed it (twice) then decided to start using it since my dad has offered to give me 2 face cords of seasoned ash. I grew up using a wood stove my whole life, but never a complicated system like this. The system was obviously used, as it took me nearly 4 hours to clean the creosote from the system. Drafts pretty well for a 25 foot chimney (some back draft sometimes -- I've set my smoke detector off a few times, but I didn't have a window in the basement cracked) and has its own separate thermostat, ran by a limit switch. Long story short, the whole system seems to work pretty well I think, but I'm having a few issues that I cannot seem to resolve no matter what I do. I stupidly messed with the limit switch before taking a picture of where the previous owner who obviously used it had the settings. The furnace blower kicks on to blow the hot air through the house, but even with a raging fire going and the damper completely closed (I guess mine can be totally closed and still vent fine, it's more of a bypass) I'm only getting lukewarm air through the house, even with the manual thermostat cranked up and the front blower raging and acting like a bellows. Can anyone explain why? I can't afford to spend $3000 on propane again this winter with my first baby on the way.
