I was all set to go with a 70,000 BTU Osburn 2200 when I started to look into the 100,000 BTU Osburn 2400 with the idea that bigger is better. A look through the owners manual caused me to think that the 2400 might be too much for my situation. Here's what jumped out at me:
1.5.3.3 Exterior Chimney
Chimneys constructed outside of the home on an exterior wall should be avoided if possible, especially in
colder climates. Exterior chimneys may not draft well and in fact may down draft (reverse flow) due to the
difficulty in heating them up to operating temperature while trying to evacuate the stack gases. All else
being equal, cooler chimneys will have less draft than hotter ones; this may lead to creosoting and poor
performance. If an exterior chimney is used to remove the stack gases the best results will be obtained by
using a connector vertically off the unit to the highest possible point before elbowing off horizontally to the
chimney. For efficiency and safety reasons the stove must not be installed with an insulated chimney
connected directly to the appliance.
This paragraph confuses me to be honest. It can't be found in the 2200 manual. I'm concerned about the final sentence. I was planning to drop an insulated flex liner down my existing exterior chimney. This seems to be a no-no for the 2400, although I can't quite figure out why. Could it be that this unit is just too much for my situation?
Thanks,
Mike
EDIT: Just realized that I had downloaded the .PDF file for the 2400 stand alone rather than the insert.
