Section 3-3: Installing a Wall Mounted Vent System
This section applies to installations where the shortest possible vent
run is through the wall. Refer to Appendix A - Power Vent locations,
to ensure the planned Power vent location is acceptable. Refer to the
table below for vent run requirements. Please note, images are shown
without screens for clarity purposes. However, your fireplace should
not be operated without proper installation of screens.

adhere to the following guidelines:
Ensure the maximum vent run does not exceed 100'
Ensure the number of 90° elbows does not exceed 6
Ensure the number of 45° elbows does not exceed 12
