DUCTING:
The option of ducting allows heat from the fireplace to be transferred to a different area. The maximum total length for the ducting is 20 feet (6.1 m). There are four (4) duct outlets that can be used (see Figure 27), however, the blower puts out 200 cfm no matter how many ducts are used. Therefore, the more ducts there are, the less air goes through each one. A short, straight duct maximizes its heating ability as air in the ducts is restricted by the length and number of bends in the pipe.
For the first 24 inches (610 mm) of ducting, 1⁄2 inch (13 mm) of clearance
is required. After 24 inches (610 mm), the duct can be run with 0 inch (0 mm) clearance, though 1⁄2 inch (13 mm) is preferred. To avoid heat loss, insulate the duct whenever it passes through an unheated area (i.e. crawl space). Insulating the ducts elsewhere helps the efficiency of the ducting system.
Standard galvanized ducting and heat registers are to be used. Simply remove the desired cover plate from the outside of the firebox and attach a 6 inches (152 mm) starter ring. Make sure to
