Assembling Pipe Sections
Insert the inner flue of section A into the flared inner flue of section B.
Start the outer flue of section A over the outer flue of section B (see
Figure 8.3).
Note:
The end of the pipe sections with the lances/tabs
on it will face towards the appliance.
Once both inner and outer flues are started, press section A onto
section B firmly until all lances have snapped into place. Check to
To attach the first pipe section to
the collars, slide the male end of
the inner vent of the pipe section
over the inner collar on the firebox
assembly. At the same time, slide
the outer flue over the outer collar
on the appliance. Push the pipe
section into the appliance collar
until all the lances (Figure 8.2) have
snapped in place. Tug slightly on
the section to confirm it has com-
pletely locked into place. It is ac-
ceptable to use screws no longer
than 1 inch to hold outer pipe sec-
tions together. If predrilling holes,
do NOT penetrate inner pipe.

• Overlap pipe slip sections at least 1-1/2 inches.
• Use pilot holes for screws.
• Screws must not exceed one inch long.
• Pipe may separate if not properly joined.
WARNING
make sure they have snapped together (see Fig-
ure 8.4) and the seams are not aligned (see Fig-
ure 8.5). Tug slightly on section A to confirm it has
completely locked into place.
For 90° and 45° elbows that are changing the vent
direction from horizontal to vertical, one screw
minimum should be put in the outer flue at the
horizontal elbow joint to prevent the elbow from
rotating. Use screws no longer than 1 inch. If
predrilling screw holes, do NOT penetrate inner pipe.
Make sure that the fiberglass rope ring supplied in the manual bag
seals between the first vent component and the outer appliance
wrap (see Figure 8.1).
