I. Auxiliary Convection Air System
Note:
Both the outside air and auxiliary air kits are installed
on the right hand side of the fireplace.
The auxiliary convection air system allows the option at
the time of installation of the fireplace, to run a 6 inch
(152 mm) diameter duct to the outside of the home, and
bring outside air over the fans where it is heated and then
distributed into the room. This produces a postive pres-
sure inside the home.
Figure 3.13 Auxiliary Convection Air Duct
Alternatively, a 6 inch (152 mm) duct can be run to an-
other location in the home and used as a cold air return
within the home and distributed into the room where the
fireplace is located. See Figure 3.13.
If no ducting is installed, the fans will pull air from the
room and re-circulate heated air back into the room.
