No additional aiming is required because the eligible appliances are protected no matter where they <br />are located within the "Zone of Protection". Therefore, the spray is not to be impeded in any manner. <br />When an appliance such as an upright broiler or salamander is part of the cooking appliance lineup, a <br />dedicated appliance nozzle must be used to protect it. The ZD nozzles cannot protect cooking appliances with <br />an enclosed cooking area such as an upright broiler or salamander. No ZD nozzles are required above the <br />upright broiler protected by a dedicated nozzle, however the ZD nozzle located to the right and left of <br />the appliance must be no more than 6 inches from the edge of the appliance. The illustration below <br />reflects the situation described above. The location of the upright broiler is now fixed and the appliance must <br />remain in this location. <br />Dedicated appliance protection of salamanders, cheese melters, chain broiler or a range with a back-shelf is <br />always in addition to the zone defense nozzles located overhead. <br />DEDICATED APPLIANCE <br />NOZZLE PROTECTION <br />APPENDIX A - Page 34 of 49
