Installing Vent Components - Heat-N-Glo Grand-50-D Manual

B. Installing Vent Components
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component (3 foot straight pipe
minimum) to the starting collars of the fireplace:
• Apply a 3/8 inch (9.5mm) bead of stove cement around
the inner pipe 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 fireplace top.
• 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 pipe line up, rotate the
pipe section clockwise about one-quarter (1/4) turn. The
vent pipe is now locked together.

2. Continue Adding Vent Components
• Continue adding vent components, locking each succeed-
ing component into place.
• Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system.
• 90° elbows may be installed and rotated to any point
around the preceding component's vertical axis. If an el-
bow does not end up in a locked position with the pre-
ceding component, attach with a minimum of two (2)
sheet metal screws.

3. Install Support Brackets
For Horizontal Runs - The vent system must be supported
every five (5) feet of horizontal run by a horizontal pipe support.
To install support brackets for horizontal runs:
• Place the pipe supports around the vent pipe.
• Nail the pipe supports to the framing members.
For Vertical Runs - The vent system must be supported
every eight (8) feet (2.4m) above the fireplace flue outlet by
wall brackets.
To install support brackets for vertical runs:
• Attach wall brackets to the vent pipe and secure the wall
bracket to the framing members with nails or screws.
