My wood furnace has a 16" round off of the top feeding back into my propane furnace. That setup is way too small.I thought so myself I was debating on adding one more on... it is a six inch duct coming out of the top now
My Yukon has 24x24 plenum, (2) 8x24 ducts coming of that. That will flow a lot of air! Your 16" round is almost 200 sq in., his single 6" is only 27! fire hazard city!My wood furnace has a 16" round off of the top feeding back into my propane furnace. That setup is way too small.
I agree. That doesn't really change anything. Insurance company definitely looking to get outta policyYeah some (most) HO ins co's are just looking for a way of getting out of covering wood stoves furnaces!
Do the math, (1) 12" is around 108 sq in. (2) 6" is only 54 sq inches! Also, you have to compare actual BTU rating, firebox size, and CFM of the duct blower, the Menards furnace with (2) 6" holes likely was a lot smaller furnaceWell it had the single 12" round duct hook up so would two 6" be good? Because furnaces at menards of a similar size out of the two they had there one had a single 12" hole out the top and one had two 6"
What is the make & model?
And this is more seat of the pants than anything - but looking at that pic, with the way the duct immediately goes down, that looks like a heat trap that could cause some very serious grief if there were a power outage or blower malfunction while there was a wood fire burning.
