OUTSIDE AIR KIT
(fireplace and AC chimney)
The outside air kit is optional on the WRT3820WS 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
(

, 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
