Assembling Pipe Sections
Insert the inner ue of section A into the ared inner ue of section B.
Start the outer ue of section A over the outer ue of section B (see
Figure 8.2). Note: The end of the pipe sections with the lances/tabs
on it will face towards the appliance.
Attaching Vent to the Firebox Assembly
To attach the rst pipe section to the collars, slide the male end of
the inner vent of the pipe section over the inner collar on the rebox
assembly. At the same time, slide the outer ue over the outer collar
on the appliance. Push the pipe section into the appliance collar until
all the lances (see Figure 8.1) have snapped in place. Tug slightly
on the section to con rm it has completely locked into place.

INCORRECT
CORRECT
Once both inner and outer ues
are started, press section A onto
section B rmly until all lances
have snapped into place. Check
to make sure they have snapped
together (see Figure 8.3) and
the seams are not aligned (see
Figure 8.4). Tug slightly on sec-
tion A to con rm 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.
For 90° and 45° elbows that are
changing the vent direction from
horizontal to vertical, one screw
minimum should be put in the
outer ue at the horizontal elbow
joint to prevent the elbow from ro-
tating. Use screws no longer than
1 inch. If predrilling screw holes,
do NOT penetrate inner pipe.
