Horizontal venting? How far?
I want to put in a direct-vent fireplace, but I need to run it horizontally from the fireplace to the outside wall. The distance is about 10-12 feet. The problem is that I can't go vertical more than a foot or so.
I have looked at some various makes of fireplaces like Heat-n-Glo, Kozy Heat, Quadrafire. The only one that *appears* to go horizontally from the fireplace is Kozy Heat. They show they need a 1/4" rise per foot of horizontal run.
Does this mean I can exit the Kozy Heat fireplace with say a 45 degree angle and take it right into a horizontal run of 12 feet to the exit vent?
Other makes say you need like 2 feet of vertical for 3 feet of horizontal.... I'm very confused.
