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
Attaching Vent to the Firebox
Assembly
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
completely locked into place. It is
acceptable to use screws no longer
than 1 inch to hold outer pipe sections 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).
