See Figure 13. When ducts are used, they shall be of the same cross° sectional area as the free area of the openings to which they connect. The minimum short side dimension of rectangular air ducts shall not be less than 3 inches (76.2 ram)+ See Figure 13+ OUTLET AmR DUCT Water Piping Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injup] or death.

If the free area through a design of louver or grille is known, it should be used in calculating the size opening required to provide the free area specified. If the design and free area is not known, it may be assumed that wood louvers will be 20°25 percent free area and metal louvers and grilles will have 60°75 percent free area. Louvers and grilles shall be fixed in the open position or interlocked with the equipment so that they are opened automatically during equipment operation. Special Conditions Created by Mechanical Exhausting or Fireplaces: operation of exhaust fans, ventilation systems, clothes dryers or fireplaces may create conditions requiring special attention to avoid unsatisfactory operation of installed gas utilization equipment. +MIXING VALVE HOT WATER OUTLET ON WATER HEATER WATERHEATER FIGURE14.
