HE350 - Installation and Operation Manual
63
This configuration can be found inside the chase, but must at all times maintain clearances to combustibles.
The following figure is shown as an example.
To complete the installation, make a hole of 1/4" to 1/2" (6 mm à 13 mm) bigger than the insulate pipe
diameter in the outside wall of the house at the chosen location. From outside, place the outside wall
termination
(E)
in the hole (open side down) and fasten the register to the wall, with screws.
Place the insulated pipe over the wall termination tube and over the fireplace outside air connector. At
each end, carefully pull back the insulation and plastic cover, exposing the flexible pipe. Attach the flexible
pipe using pipe clamps. For a better seal, you may also use aluminum tape. Wrap the tape around the joint
between the flexible pipe and the air inlets. Carefully push the insulation and plastic cover back over the
pipe. Fix the plastic in place using aluminum tape.
