Yes Rob that is the plan for two reasons. The AK180 requires a 7" exhaust and the 220 an 8" so I need only a 7" but the Anthra Kings have another need. The breach to the stove is way down low in order to get the max out of the airflow pattern. This means that fly ash tends to accumulate there and with heavy use starts to block up. A cleanout tee is the first thing to put in the flu line. If a stove needs 7" then it will not get that if the flu is partially blocked with ash.
If we approximate cross sectional areas for a 6-8" pipe (pi being 3.14 and that is close enough for a dumb horse farmer)
6" 28 sq in+
7" 38 sq in+
8" 50 sq in+
So 8" it is and as I build the flu you will see two clean out tees that I think are advisable in AK line installs. The AK180 is the best of the series for my application and once it was announced I was hooked. You see Dave you did not have to apply that hammer lock in order to force me to buy
- well I had to make up an excuse for the wife. I get the full 26 tubes for ultra efficiency. Yes, the stove is pricey but I want every gram of coal to count. This is not where you want to cheapskate. AK 180 + LEHIGH RICE - YEAH, MOTHER NATURE BEING IT ON, LET'S TRY THAT AGAIN - let's see what you got!
The slight down side is that this sucker is a big baby (it's a 220 in disguise) but that does not deter me in my application. In heavy use I used to clean that lower T out every Sunday morning with my AK110 by removing the cap and yes the stove remained on. More pics later as endless boring chores await my attention. Tomorrow is another day - I'm having a blast.
