The inspection company does Saturday and Sunday appointments. Open wire splices were observed in the attic space. This is non standard. All wire splices must be enclosed in a covered junction box. We recommend enclosing the open wire splices in an approved junction box by a qualified licensed electrician. The flexible gas supply pipe passes through the furnace housing. Vibration from the furnace can wear through flexible gas pipe which could cause a gas leak. SDG&E is "Red Tagging" this condition as they considered it to be unsafe. Due to this condition we recommend a rigid cast pipe be installed from the gas regulator through furnace housing, to the exterior of furnace housing by a qualified licensed HVAC contractor.
