VERTICAL TERMINATION
Vertical Through the Roof Applications
Your Gas Fireplace has been approved for:
a) Vertical installations up to 40 feet in height.
b) Two sets of 45° elbow offsets within these vertical
installations. A vent pipe from 0 to a maximum of 8 feet can
be used between elbows.
c) Wall straps must be used to support offset pipe every 4 feet
This application will require that you first determine the roof pitch
and use the appropriate venting components.
