When i have to use wood fireplace 30 degree elbows?
By Tyler M. - Fireplace Specialist on November 9, 2011
Answer:You would use these 30-degree elbows on a chimney run that is obstructed in some way from a straight vertical run. For example, if you have to go around a rafter or some other obstruction. It is always best to vent 100% straight vertically with class A chimney pipe such as this if you can, but these elbows will allow for an offset to get around any obstruction.

What kind of guidelines are there for bends in the chimney pipe? Is there a minimum straight run after the bend? I need to go around a room, preferably without changing where the pipe exits the roof. Is it OK to do a 30° bend and return to vertical then a second combo to get the pipe to its original spot?
By Tyler M. - NFI Certified Specialist on August 8, 2013
Answer:Chimney offset guidelines are established by the manufacturer of the fireplace. Class A chimney pipe only allows a maximum of a 30-degree offset, but each model has its own restrictions and limitations on number of elbows used and the total offset distance. However, a simply offset such as shown in this picture is fairly common and should not be a problem. We recommend checking with your fireplace's manufacturer for more information.
