If the combustion air passageway cannot terminate outside of the skirting or 
enclosure, a permanent opening with a minimum of 50 square inches of 
unobstructed infiltration (free area) for ventilation air must be provided for 
adequate combustion.  This permanent opening must be located no less than 12 
inches from the bottom of the enclosure or skirting.

Slit the corners of connector duct down to the top of the base assembly. If metal 
projects more than 1-inch above the top of the base assembly, trim the flanges down 
to 1-inch. While the top of distribution duct is being pulled up with one hand, bend 
down each side of the connector duct tightly to the base assembly with the other 
hand. This assures a tight connection between the base assembly and the connector 
duct and that the distribution duct will be full size. Use high temperature tape and/or 
high temperature silicone caulking on all joints and seams to minimize air leakage. 
Secure the base assembly to the floor with two screws in the front flange.

The O1COT-BASE cottage base (Figure 1B) is required for a freestanding cottage 
base installation.  The cottage base is designed to permit the installation of a 6-inch x 
14-inch register in each of the two side panels and the front panel.
