B. Installing Vent Components
The glass must be taken off again for positioning the logs
when the unit is finally installed in place and finished around
it. Re-install the glass door. Attach vent system to the top
starting collars.
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars
of the fireplace:
Apply a 3/8 inch (9.5mm) bead of stove cement around
the 5 inch (127mm) fireplace starting collar.
Make sure that the fireplace rope gasket supplied with
the fireplace seals between the first 8-5/8 inch (219mm)
vent component and the outer fireplace wrap.
Lock the vent components into place by sliding the con-
centric pipe sections with four (4) equally spaced interior
beads into the fireplace collar or previously installed com-
ponent end with four (4) equally spaced indented sections.
When the internal beads of each 8-5/8 inch (219mm)
outer pipe line up, rotate the pipe section clockwise about
one-quarter (1/4) turn. The vent pipe is now locked together.
The first 90° elbow installed in the vent system of a rear
venting fireplace
MUST BE
in a vertical position.
