Product Description

HearthStone Shelburne 8370 / 8371 Outside Air Adapter

3" OUTSIDE AIR ADAPTOR 93-53700

IF YOU INTEND TO USE THE OPTIONAL BLOWER, you will not be able to use the rear inlet position on the rear outside air box. When installing the outside air kit in combination with the optional blower, the outside air must enter the rear outside air box from the left or right sides.

Important: Before you install the outside air kit, determine where the duct for the rear outside air box will originate. The duct can be attached either to the back, the left or the right sides of the rear outside air box by changing the position of the intake and blank cover plates.

When considering placement of the duct on the inside and outside of the house, keep in mind the need to avoid wiring and structural members of the house. Locate the termination of the duct on the outside wall in such a manner as to preclude the possibility of obstruction by snow, leaves, or other materials. Screen the outside termination with a ¼” x ¼” mesh rodent screen, and cover it with a rain/wind proof hood. Periodically check the screen to  ensure it is not blocked by debris such as spider webs or leaves
