Drop a plumb bob down from the ceiling to the positionof the appliance flue exit, and mark the location where the vent will penetrate the ceiling. Drill a smallhole at this point. Next, drop a plumb bob from the roof to the hole previously drilled in the ceiling,mark the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters, or otherframing will obstruct the venting system. You maywish to relocate the appliance, or to offset, toCeiling Joistavoid cutting load bearing members.3.
