OUTSIDE AIR KIT (fireplace and AC chimney)
The outside air kit is optional on the Ladera™ fireplace, but mandatory on
the AC chimney. It can be burned drawing air only from the house. When
the fireplace is in operation with the door closed, it will pull only a slight
amount of air from the house. Nevertheless, the outside air kit might be
mandatory in your jurisdiction, check your local building code.
To install an outside air intake on the fireplace:
1. Remove the obstruction plate and the access plate (both are super-
impose) located on the bottom of the left side (Figure 19, part 2).
2. Screw the obstruction plate inside the primary air box using only two
screws on the bottom (Figure 19, part 3).
3. Reinstall the access plate exposing the 5 inch diameter hole topped
by a triangle (Figure 19, part 4).
