NOTE: When installing this vent system in a chase, it is always
good building practice to insulate the chase as you would the
outside walls of your home. This is especially important for cold
climate installations. Upon completion of building your chase
framing, install the vent system by following the instructions in
this manual. Remember to build the chase large enough so that
minimum clearance of combustible materials (including insulation)
to the vent system are maintained.

pipe lengths, elbows and horizontal or vertical termination kit.
All rigid pipe vent system components lock into place by sliding the
concentric pipe section with four (4) equally spaced interior beads
onto the appliance collar or previously installed component end with
four (4) equally spaced indented sections. When the internal beads
of each starting outer pipe line up, rotate pipe section clockwise 90°
(approximately 3 inches). The vent pipe is now locked together.

Vertical Through the Roof Applications (Figure 62)
Your Gas Fireplace has been approved for:
a) Vertical installations up to 40 feet in height.
b) Two sets of 45 degree elbow offsets within these vertical
installations. From 0 to a maximum of 8 ft. a vent pipe can be
used between elbows.
c) Wall straps must be used to support offset pipe every 4'.
