Hi everybody!! My name is Josh. I am new to fireplaces and inserts altogether. I just recently bought a cheapo Vogelzang Colonial wood burning insert from Northerntool.com. Like i said i don't know much about fireplaces but i have a rectangular damper and the exit pipe for the insert is 6". How do i get through that damper with the flu pipe? Since i have a ceramic flu it is ok just to run 5' of flex stainless flex pipe off of the insert? I am not trying to be cheap but i just don't have the money to run a $500 pipe all the way up the fireplace. Any input will be helpful and appreciated. Thanks.
