PLAN THE DUCTWORK
The Scirocco downdraft system is designed to offer wide flex- ibility in ducting. The interior blower can be ducted in four different directions; down, left, right or back using a 3 1/4" X 10" rectangular vent. The remote blower can be ducted in three directions; down, left or right using a 10" round vent. FIGURES 1 and 2 illustrate venting options.
The remote blower requires a separate wiring cable that should be installed at the same time that the ductwork is installed. For best results, 10" duct is recommended for the remote blower. A damper plate is included in the box with the remote blower and must be attached over the opening of the front of the downdraft blower box. Remote blower can be mounted on either an outside wall or the roof of the home.

CALCULATE THE DUCTRUN LENGTH
The ductwork length should not exceed 35 equivalent feet for 3 1/4" X 10" duct, or 55 equivalent feet for 9" or 10" round duct. Calculate the length of the ductwork by adding the equivalent feet listed in FIGURE 3 for each piece of duct in the complete system. An example is given in FIGURE 4.
For best results, use no more than three 90° elbows. Make sure that there is a minimum of 24" of straight duct between elbows if more than one is used. Do not install two elbows together. Round duct is recommended instead of rectangular duct especially if elbows are needed. For internal blower models, rectangular duct should be transitioned to 6" round as soon as possible.
