Wood furnace woes?
We installed a Yukon Husky/Eagle wood-oil combo recently and I was hoping others here have experience with these furnaces. It took a while to get the heat rise adjusted, i.e., the blower speed, so that when burning oil the fan wouldn't cool down the unit to the point of shutting off the blower before reaching the temp that was set on the thermostat. Still I'm only able to get a 75 degree heat rise rather than 90.
I'm wondering, however, about the wood side of things. The furnace doesn't seem to draw enough air to sustain a really hot fire. If I leave the ash drawer cracked open the fire is hot enough to keep the plenum temp between 120 and 160 degrees. If I close the drawer the fire cools down so that the blower short cycles. The draft control seems to be working correctly and I'm burning seasoned maple and ash.
The guy I keep getting at Yukon is telling me that it isn't cold enough outside and that's why it's shutting down (he doesn't get it that the thermostat isn't shutting the blower off, it's the fan limit switch).
Does anyone have a suggestion? Thanks!
