Is this used for fireplace chimney venting of smoke?

This elbow is used as a venting system for a direct vent (gas) fireplace or stove. The inner pipe is for exhaust, and the outer pipe brings in fresh air from outside. For more information on direct vent fireplaces or stoves, please see our Gas Fireplace and Stove Buying Guide here

Answer:This product is intended for use with "direct vent" gas fireplaces only and cannot be used in a wood burning application.
Typically, it is necessary to use Class A chimney pipe to vent a wood burning fireplace. If you have a wood burning stove, you will need to use single or double wall stovepipe, then transition to Class A chimney pipe before passing through the first combustible wall or ceiling.
Please advise as to what type of fireplace/stove you have. If you are able to provide the manufacturer name and model number of the unit, I will be happy to recommend the best setup for your venting needs.

I have a Napoleon Gas-Fired Direct Vent Wall Furnace and need to remove a 90 degree swivel elbow from a piece of horizontal pipe. But, I cannot get it loose again. Is there some tool or trick to getting the pipe to separate? If not, is there a local vendor who can separate the pieces?

Answer:The individual sections can indeed be difficult to separate. After ensuring that the section is untwisted completely, you can use a narrow shank flat head screwdriver to work around the perimeter of the pipe. Moving slowly, you should be able to pop each individual lance loose, if the screwdriver is narrow enough. This is the best method I have come across, as the manufacturer does not offer a specialty tool to pull the sections apart again.
