Hi. I have a Temco Insert that was bought a number of years ago for our house. We have just now built the part of the house for the fireplace and are in need of an offset to get around the beam in the middle of the room. We have found one 30 degree offset and are in need of another 30 degree offset and an 18" piece of Temco (8" dia. pipe) to complete the offset. Does anyone have any leads on where to find another offset and short piece of Temco pipe?? Thanks.
