I emailed Selkirk Corp. yesterday with some concerns/questions with some pics. about my chimney pipe, like to stay somewhere near the safety parameters, guess it's fair to say that it's not a professional installation but in some ways better, like he says every 8' should have wall supports and bands, I didn't measure it but I'm darn close with a 22ga. mid floor pipe flashing that has a 1" high lip that is clamped to the pipe but later I will add some more bands.
"The insulated chimney pipe is rated for 1000 degrees continuously, 1400 degrees for one hour, and 2100 degrees for 10 minutes 3 times in an hour. The purpose of the insulation in the chimney is not to keep the chimney outer surface fr"om getting hot. The insulation is there to reduce the clearances to combustibles to a minimum of 2”. The surface of the chimney will get hot. I don’t know what type of stove pipe you have. I believe it may be a little too thin for a wood stove. The stove pipe that we manufacture is 22 gauge. Looks like you could use more supports. Wall bands are required every 8’. The piece of wood is under the tee is a fire hazard.
I hope this helps explain some of your questions."
AND>>> "Also I wanted to add that you may want to purchase a stove pipe thermometer. The stove pipe temperature should be regulated to 300-350 degrees. This will help prevent over heating the chimney system.
Best Regards,"
