Hi folks ... hoping someone is able to assist a newbie with a potentially embarassing question. I just purchased a used Jotul Firelight DV (1998 model) and am prepping my walkout basement for installation. Rather than installing in a corner, I built a diagonal wall to pull the stove out of the corner. The vent on this stove comes directly out of the rear and I would like to put a straight 12" pipe straight out of the stove and through the wall before routing the vent 90 degree up (wife doesn't want to see the pipe at all so want to run the vertical section behind the wall). I planned to vent up about 5 ft and then another 90 elbow to a 36" vent out the wall. To the point, I would like to know if it is ok to use the 12" horizontal directly off the stove. As mentioned, I will have 5 ft of vertical vent but just not immediately off the stove. So... stove... 12" horiz run.... 90 elbow... vert 5 ft .... 90 elbow .... 3 ft horiz to wall termination. Thanks much for any assistance you can provide !!
