The log set is rich in color and detail, provide a real wood log appearance. They are produced by a unique process where ceramic fibers are melded together in the form of a variety of log shapes. They are then hand painted and accented to create the most realistic looking logs available. The properties of the ceramic fibers allow the logs to withstand the extreme temperatures that they are exposed to within the combustion chamber of the fireplace. It is for this reason that our Phazer® logs are guaranteed for life!

Direct Vent Technology
Napoleon`s Direct Vent Gas Fireplaces do not require a chimney and can be vented directly through a wall or roof. The direct vent draws its combustion air from outside while venting to the same outside atmosphere.
