DUCTING:
The option of ducting allows heat from the replace to be transferred to a different area. The maximum total length
for the ducting is 20ft (6.1m). There are four duct outlets that can be used, however, the blower puts out 200cfm
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 rst 24in (61cm) of ducting, 1/2in (1.3cm) of clearance is required. After 24in (61cm), the duct
can be run with 0in clearance, though 1/2in (1.3cm) 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 efciency 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
rebox and attach a 6in (15.2cm) starter ring. Make sure to foil-
tape all seams to prevent leaking. Ensure all ducting meets local
building codes.
