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.
!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
•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

!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 IMPROPERLY. SEE FIGURE 11.
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.
