| | DRAWING SHOWS THE ENTIRE DUCT IS ENCLOSED FROM THE HOOD |
| | TO THE IN-LINE EXHAUST FAN, THEN ENCLOSED AGAIN FROM |
| | THE OTHER SIDE OF THE IN-LINE FAN TO THE TERMINATION |
| | LOCATION. ACCORDING TO MASTER PERMIT # 17020796 SHEET |

| | OUTDOORS, THE FAN SHALL BE LOCATED IN A ROOM OR SPACE |
| | HAVING THE SAME FIRE-RESISTANCE RATING AS THE DUCT |
| | ENCLOSURE. ACCESS SHALL BE PROVIDED FOR SERVICING AND |
| | CLEANING OF FAN COMPONENTS. SUCH ROOMS OR SPACES SHALL |
| | BE VENTILATED IN ACCORDANCE WITH THE FAN MANUFACTURER?S |
| | INSTALLATION INSTRUCTIONS. |

| | SYSTEM SHALL BE INSTALLED IN ACCORDANCE WITH THE |
| | LISTING AND THE MANUFACTURER?S |
| | INSTRUCTIONS. PARTIAL APPLICATION OF A FIELD APPLIED |
