Hi! I am in the process of removing a propane stove in our living room and replacing it with a wood stove. The exhaust from the propane stove went out the side wall (log home). The hole from the exhaust was cut for a 6" pipe, I don't want to have to enlarge the hole. So...I'm looking at a wood stove that is set up for 8" pipe, can I safely reduce the chimney pipe size to 6", will this greatly effect the exhaust??? Or should I look for a smaller stove. Thanks a bunch, Chris P.s. why is stove pipe (triple wall) so freaking expensive???
