Vertical vent sections within enclosures require a minimum clearance of1” (25mm) around the vent pipe.The LVX series requires a minimum enclosure height, as illustrated (dimension L), measured from the bottom of the appli-ance. For temperature requirements, this area must be left unobstructed. Some venting configurations that require morevertical rise will require a larger enclosure to provide minimum vertical clearance between vent pipes and combustibles.note:
