Dave. I agree. I think pitch in any amount would really be different than wood pd for pd. I think pitch would be considered an accelerant.
Sean, cleaning isn't rocket science. It's physically removing soot/creosote by whatever means nescessary, brushes, rods, I use rotary cleaning tools for the most part. Easier and more effective. A win, win. But the sometimes tricky part is doing it effectively and thoroughly. As in verifying your pathway and the effectiveness of the cleaning. Cleaning a chimney is often the easy part, cleaning the appliance has its tricks and challenges.
The temps that you are looking for can vary somewhat by style of appliance and how you monitor them can also vary quite a bit. The most common and easiest method is a magnet thermometer on single wall connecting pipe. Placed 12-18"s above the flue collar readings of about 250-550f are considered a 'clean' burn. Some thermometers or people may vary from those numbers slightly but that's the gist of it.
If you have a freestanding woodstove made of steel. Then reading the stovetop temperature with a magnet thermometer 4-6"s from the flue collar and placed off centre to either the left or right(or better yet use a couple of thermometers, they're pretty cheap) and placed on the thick steel top plate you want to see temps of 400-700f. Robust secondary combustion won't occur until about 400 stovetop so up to that temp you are shooting smoke straight up the chimney(smoke is unrealized heat and pollution). I run my steel stove right up to 800+f stovetop sometimes, but I'm crazy like that. Lol.
There are lots of different ways to monitor temps and different types of appliance will have slightly different temp zones that you will be looking for. For example a cast stove will run at(or should to avoid damage) slightly cooler temps then those I mentioned for a steel stove. Inserts are inherently hard to monitor temps in magnet thermometers placed above the door is one way if it doesn't protrude enough to get a 'stovetop' reading. You need to learn to burn by the 'look' of the fire more with a insert. Also infrared temperature guns are super handy for wood burning systems. For checking temps and for checking temps of surrounding combustible items too. 100f above ambient(room) temperature is considered the upper safe limit for heating items up. Usually around 165-175 is the max temp you want to see of combustible items around your stove. That will be hot to the touch but you should be able to keep your hand on it for a few seconds without burning.
It's dangerous business having fire in a box inside your home. Best to equip oneself with some basic knowledge and monitoring devices.
Butch. I have a couple more courses to take this next spring and then I will be looking to re-line and install. I've held off because I wanted more practical experience. From what I've seen in the field, many don't feel the same way as myself. I find lots of issues out and about cleaning. I've only undertaken minor repairs so far.
