This has been <br /> done and reviewed by the building inspector from the city of Everett WA. <br /> The owner supplied roof curb and the specified grease duct size 12" X 12" does not allow enough clearance <br /> for 2 layers of fire wrap. <br /> It is understood by the City of Everett building official and Ocean Air Contracting that there is no <br /> combustible materials within 18 inches of the grease duct above the roof structure therefore the city of Everett <br /> will accept the installation as complete. <br /> Cordially, <br /> Arnie Bossard I President <br /> Ocean Air Contracting Inc. <br /> • <br /> 1 <br />
