Was there some reason you opted to use a 5.25 inch flue on the CS/FE100.Flue run in 4/6/8 inch at the hardware store,and there is no reducer to the 5.25 flue,so split the elbow clampto the pipe.Second question,will there be a problem of using too many 90*els in order to vent to the outside.I have to go through a wallso it will require 3 and 4 to 6 feet of pipe,and cap on top.Here is the background on this question,in my hotrod days the exhaust on the cars we ran were short and with very little bends as posible,so back pressure would form in the system,and cut engine performance.The CS/FE100 is the engine,the flue is the exhaust ,the low speed blower and the heat push the smoke out the flue.Is cfm on the blower along with the heat as heat rises,enough to vent this unit,without causing too much smoke to the product and too much retained heat in the unit.Therefore back pressure.
Inquiring minds want to know.
Thanks,
