Typical construction is for 'Pant-Leg' hood connections to the 4" x 16" vent connectors (Fig. 5). Vent stacks must be watertight and fit inside the vent connector openings. Fig. 7 – 14 – If using the 'Pant-Leg' duct, a mini vent hood (Fig. 8), positioned about 18" above the flue exit at the rear of the dishwasher and connected to existing duct work, must be used for the flue gases. The volume of flue exhaust in the mini vent hood should not exceed 200 CFM. If using the 'Pant-Leg' duct, a mini vent hood (Fig. 8), positioned about 18" above the flue exit at the rear of the dishwasher and connected to existing duct work, must be used for the flue gases. The volume of flue exhaust in the mini vent hood should not exceed 200 CFM. Fig. 8 In either case, if a powered means of exhaust is used, an electrical interlock must be provided to allow the flow of gas to the dishwasher burner only when the exhaust system is in operation. For additional information, refer to the National Fuel Gas Code, ANSI Z223.1, NFPA 54. In all cases, local codes will prevail. – 15 – RATE OF EXHAUST FLOW CALCULATIONS RATE OF EXHAUST FLOW CALCULATIONS The Rate of air flow required for a vent hood is now based on the linear length of the face of the hood instead of the area of the hood opening. The length of the hood is measured along the front side that is parallel with the front line of the appliance (LENGTH, Fig. 9). For hood designs not covered by these calculations consult the latest edition of the IMC or other local codes. Type of Hood CFM per Linear Feet of Hood Wall Mounted Canopy Single Island Canopy 200 CFM 400 CFM Subtract make-up air flow supplied directly to a hood cavity from the total exhaust flow rate of the hood, if applicable. Fig. 9 – 16 – ELECTRICAL CONNECTIONS — DISHWASHER ELECTRICAL CONNECTIONS — DISHWASHER WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES. THERE MAY BE MULTIPLE CIRCUITS. BE SURE ALL CIRCUITS ARE DISCONNECTED. Some machines may have more than one electrical power supply. All supplies MUST be disconnected. Motor(s) Connect a permanent electrical power supply to the terminal block in the control box. Three-phase motor(s) must rotate the impeller in the direction of the arrow found on the pump housing of the motor pump unit (Fig. 10), the drive motor can rotate in either direction. Before placing the machine into service, a check must be made to verify correct rotation. Only one motor needs to be checked, as the machine is wired at the time of manufacture so that all motors will rotate the same direction. Fig. 10 If the impeller does not rotate in the direction of the arrow, DISCONNECT POWER SUPPLY(IES) to the machine and interchange any two power supply leads at the control box terminal block. On machines with a circuit breaker box, reverse any two leads at the incoming power supply block in the circuit breaker b...
