My bad on the Class-B pipe info. What Juice said sounds right to me. I have only dealt with 2 wood burning stoves in 23 years of mobile home repair. Both were roof jobs. Both reused the existing stacks. I have seen other wood stoves in homes, but they were not involved in my repairs.
Here in Fresno, our coldest month December, has an average high temp of 54 and average low of 45 degrees historically. We certainly get some very cold days too, but not many. Very few wood burners in my area. Even fewer now that we have so many "No Burn" days in the winter.
Today is PERFECT!
