Water is collected and then redirected. Exhaust performance increases in higher wind conditions due to natural ventilation design Designed to withstand 130 MPH at grade wind-speeds. Can be modified to meet higher wind speeds Damper Operation works up to 80 of damper, depending upon the throat size.

This highly effective & highly efficient ventilator has helped buildings stay cool for over 50 years. Page 3 of 12

4 Natural Ventilation System Design A Natural Ventilation system provides a natural intake for fresh supply air and a natural evacuation point for hot air and fumes. Warm air naturally rises to the ceiling, natural ventilation lets it escape. This system has zero operating cost, zero maintenance costs, and makes for a cooler and more comfortable facility Our 50 years of experience gives us the ability to design the optimal ventilation solution for your facility. With our experience and time tested formulae we can design the optimal ventilation system for your facility. Visit MoffittHVAC.com/Vent-Selector to begin designing a Natural Ventilation system yourself. Simply input the variables for your building (dimensions, heat load, etc.) and you ll find out how much ventilation your building will need.

10 MoffittVent Operation and Maintenance Manual MAINTENANCE INSTRUCTIONS MoffittVent Ventilators are designed to provide many years of smooth, trouble-free service with only a minimal amount of periodic maintenance required. Ventilator dampers are controlled by a continuous steel line shaft (supported by roller bearing hangers at each frame), to which is attached the rack and pinion actuators. Check pinion set screw and line shaft couplings; tighten if necessary. The rack should be perpendicular to its attachment point on the damper panel, otherwise binding may occur. Adjust by loosening pinion set screw and re -positioning pinion on line shaft. Periodically apply a liberal coating of good quality gear grease (of a viscosity suited for the expected temperatures under which vents are to operate) to pinions, line shaft bearings, fixed and moving pivots. Moffitt Ventilators are designed to be self-cleaning by action of the elements. However, the atmospheric conditions to which ventilators are exposed will dictate the nature and frequency of a program to clean and maintain ventilators. We would recommend every 4 months for the first year, then adjusts per site requirements. DAMPER OPERATORS MOTOR OPERATED - When the MoffittVent damper system is motor operated the open-close cycle of dampers is limit switch controlled. The unit will automatically shut off at the end of open or close cycle. Any intermediate damper position may be set by pushing the stop button or the starter push button unit. MANUALLY OPERATED - When the MoffittVent Natural damper system is manually operated the open-close cycle of dampers is controlled by either a wheel handle located on the roof external to the unit or manual chain wheel drop located below the unit. The Damper can be ope ned or closed to any position by simply stopping the damper in the desired location. Visual inspection of the damper location is done through access doors located next to each operator wheel. COMPONENT ACCESS Access the components inside the ventilator by removing the sheet of cladding from the side of the unit. A scaffold should then be spanned across the ventilator throat to reach to service the interior components. Remove scaffold and re-install cladding once maintenance has been completed. METAL STORAGE & MAINTENANCE - IMPORTANT If not used immediately the metal should be stored in a dry place where there is as little moisture as possible to avoid staining or white rust. Moisture from rain, snow, condensation, etc. should be avoided as it can get trapped between the stacked materials. Break the steel strapping bands used for shipment and store with the stacks or crates of metal in an inclined position. If outdoor storage cannot be avoided, protect the metal with canvas or waterproof paper cover. Leave the bottom of the canvas loose to allow for air movement. Keep the steel off the ground in an inclined position with an insulator, such as wood. Do not use plastic! Plastic can cause sweating or condensation on the metal Failure to follow above instructions could affect equipment warranty. Page 10 of 12

Throat size shall be MATERIALS The MoffittVent free area shall increase proportionally throughout so as not to restrict calculated velocities with the exhaust opening not exceeding 1.5 times the throat size All ventilators shall be capable of self-cleaning by action of the elements, with provisions for carrying water and normal wind-transported soil to the outside of the ventilator Frames shall be constructed of minimum 3/16 ASTM A36 steel plate, angle and channel, and shall be shop welded. Component parts shall be sized for ease of shipment and handling, and be field assembled After fabrication, all structural components shall be hot dip galvanized. Sheeting shall be 22 gauge (Galvalume/G90 galvanized steel substrate: choose one) (note: for mill finish sheeting must be Galvalume) for the accelerator, hood, and end wall sheeting. The sheeting shall be (choose one): Mill finish Exterior stock Kynar color to match interior wash coat Exterior stock Kynar color to match interior Kynar color 2.3. ACCESSORIES Ventilators shall be equipped with 1/2 mesh, 19 gauge, galvanized bird screens attached to 3/8 diameter galvanized rod frames. Ventilators shall be equipped with dampers, each with a permanently sealed and lubricated mechanical gear reducer. The gear reducers shall open and close the dampers by means of rack arm and pinion gear operations. The damper shall be manually operated with a continuous loop chain wheel, manual roof hood crank, or electrically operated using ¼ or ¾ horsepower, 1800 RPM T.E.N.V. motors (choose one). Dampers shall be an integral part of the ventilator and shall form an inverted cone under the hood when the damper is in the open position for 5 sizes and above, and single leaf for sizes 4 and below INSPECTION Examine alignment of structural steel prior to installation and do not proceed until structure is within tolerances established by AISC INSTALLATION AND ERECTION Install MoffittVent and accessories in conformance with approved drawings and MOFFITT specifications & erection instructions DAMAGED MATERIAL Repair or replace all damaged material.
