5. SPECIAL INSTALLATION PROCEDURES <br /> SPECIAL INSTALLATION PROCEDURES No. 11 <br /> SHORT VALLEYS/WATER DIVERTERS <br /> SHORT VALLEYS <br /> This situation occurs when a valley exits <br /> onto the roof surface well above the fascia. <br /> An extra valley cut panel is installed on top <br /> RAKE BATTEN of an existing panel so that the valley metal <br /> A B is concealed and held firmly in place. <br /> Keep the valley cut panels tight against the <br /> valley side walls so that the extra valley cut <br /> panels do not impede the water flow. <br /> (See III.) <br /> VALLEY <br /> WATER DIVERTERS'V'TYPE <br /> Gerard recommends the use of custom <br /> manufactured crickets/saddles for large <br /> RAKE BATTEN roof protrusions,following is an alternative. <br /> FIELD MADE DIVERTER: <br /> Gerard panels can be cut and bent to be <br /> used as water diverters to prevent pooling <br /> A �\ of water behind large roof protrusions not <br /> exceeding 48' (1200 mm)in width. When <br /> roof protrusions exceed 48' (1200 mm) in <br /> width, a cricket/saddle made from <br /> galvanized metal should be used. An <br /> alternative method is to install the <br /> diverters,so the water flow is shed around <br /> BACK LIP the protrusion. <br /> 3" <br /> When making a diverter, obtain the bend <br /> lines by marking a large triangle onto the <br /> BEND LINE panel by measuring 2' (50 mm) in from <br /> 1 3" each side and 3' (75 mm)down from the <br /> CUT LINE back lip in the center of the panel. (See III.) <br /> 1" "L ® To obtain the cut lines,add 1'(25 mm)to <br /> the bend lines. (See III.) Single direction <br /> 2" diverters are made by measuring down <br /> from the back lip 6' (150mm)on one side <br /> and 12'(300mm)on the other. <br /> A SPECIAL INSTALLATION DETAILS: <br /> Generally, these special details will <br /> apply for Gerard Shake panels as well as <br /> Gerard Tiles.
