Online Research shows that some vented gas fireplaces do not come with blower (Heat n Glo 8000CL). They say there is plenty of heat that comes off ceramic glass (but not tempered class) so that blowers are not required. But then Heat n Glo sells the 8000CLX with blower. What am I missing here. Will be placed in New construction, 18ft ceiling with ceiling fan, vented fireplace. Suggestions or thoughts?
