I will be adding a baro damper to my stove soon but need some guidance on what size and where to put it. Currently there is a 4" pipe from the back of the stove going up vertical (about 4 foot run) to a 4"-6" adapter to a 90deg 6" elbow that goes into the flue.
#1 Use a 4" baro in the vertical run from the stove to the adapter?
#2 Replace the 6" elbow into the flue with a T, put 6" baro on other side?
For the times I need to reconnect gas furnace it would be easier to do #1 (sucks to do but the cat can't load the stove when I'm gone for 2-3 days, my friends are all coal/wood illiterate)
