B. On the TOP of the heater
1. Attaching the First Flue Component to the Start-
ing Collars:
To attach the fi rst fl ue component to the starting collars
on the top of the heater:
• Lock the fl ue components into place by sliding the
concentric pipe sections into the heater collar or
previously installed component end.
Figure 32. Adding Flue Components
• Align the seam of the pipe and seam of the collar to
allow engagement. Rotat the fl ue to lock into place.
Use this procedure for all the components. See
Figure 32.
• Slide the gasket over the fi rst fl ue section and place
it fl ush to the heater. This will prevent cold air infi ltra-
tion. High temperature caulk may be used to hold
the gasket in platce.
2. Continue Adding Flue Components
To continue adding fl ue components in accordance with
the pre-planned fl ue system confi guration:
• Ensure that each succeeding fl ue component is se-
curely fi tted and locked into the preceding component
in the fl ue system.
For elbows that are changing the fl ue direction, two
screws minimum should be put in the outer fl ue at the
joint to prevent the elbow from rotating.

3. Assemble Slip Sections
• Slide the inner fl ue of the slip section into the inner
fl ue of the pipe section and the outer fl ue of the slip
section over the outer fl ue of the pipe section. See
Figure 33.
• Slide together to the desired length.
Figure 33. Slip Section Pilot Holes
• Maintain a 1-1/2 in. (38 mm) overlap between the
slip section and the pipe section.
• Secure the pipe and slip section with two screws no
longer than 1/2 in. (13 mm), using the pilot holes in
the slip section. See Figure 34.
Figure 34. Screws into Slip Section
• Continue adding pipe as necessary following
instructions in "Assembling Pipe Sections."
NOTICE: If slip section is too long, the inner and
outer fl ues of the slip section can be cut to the desired
length.
4. Install Support Brackets
For Horizontal Runs - The fl ue system must be
supported every 1.5 m of horizontal run by a horizontal
pipe support.
To install support brackets for horizontal runs:
• Place the pipe supports around the fl ue pipe.
• Nail the pipe supports to the framing members.
