Hey you woodchucks, quit chucking my wood!
Two options here...a power closed/spring open damper, or a fusible link style heat dump door like Yukon sells, http://www.yukon-eagle.com/FURNACEACCESSORIES/SAFETYHEATDUMP/tabid/200/Default.aspxUnless you have the recommended backdraft dampers installed than it will more than likely overheat. I've thought about this numerous times. I'd like to pull then out, but don't want my LP furnace blowing into it if it turns on.
hafta have a plenum to put that in though.
Still on sale for $1399 at Menards...as of right now anywaysFor 1699 I don't think you'd find anything on the market comparable with these features .
