Installing Flue Components
1. Attach the First Flue Component to the
Starting Collars
To attach the first flue component to the starting
collars of the fireplace:
• Apply a 3/8 inch (10mm) bead of stove cement
around the inner pipe heater starting collar.
• Make sure that the heater rope gasket sup-
plied with the heater seals between the first
flue component and the outer heater wrap.
• Lock the flue components into place by sliding
the concentric pipe sections with four (4) equally
spaced interior beads into the heater collar or
previously installed component end with four (4)
equally spaced indented sections.
• When the internal beads of each outer pipe line
up, rotate the pipe section clockwise about one-
quarter (1/4) turn. The flue pipe is now locked
together.
• The first 90° elbow installed in the flue system of
a rear flueing heater MUST BE in a vertical po-
sition.

Component to the Starting Collars
WARNING: A 3/8 INCH (10MM)
BEAD OF STOVE CEMENT MUST BE
PLACED AROUND THE INNER PIPE
HEATER STARTING COLLAR BEFORE
ATTACHING THE FIRST FLUE COM-
PONENT. FAILURE TO SEAL THIS JOINT
MAY CAUSE THE HEATER TO OPERATE

WARNING: ENSURE THAT THE FI-
BERGLASS ROPE GASKET SUP-
PLIED WITH THE HEATER SEALS
BETWEEN THE FIRST FLUE COM-
PONENT AND THE OUTER HEATER
WRAP.
2. Continue Adding Flue Components
To continue adding flue components in accordance
with the pre-planned flue system configuration:
• Ensure that each succeeding flue component is
securely fitted and locked into the preceding com-
ponent in the flue system.
90° elbows may be installed and rotated to any point
around the preceding component’s vertical axis. If
an elbow does not end up in a locked position with
the preceding component, attach with a minimum
of two (2) sheet metal screws.
3. Install Support Brackets
Figure 12 Adding Flue Components
For Horizontal Runs - The flue 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 flue pipe.
• Nail the pipe supports to the framing members.
