 A.  Assemble Vent Sections 
Attach Vent to the Firebox Assembly
Note: The end of the pipe sections with the lanced tabs 
will face toward the appliance.
Attach the fi rst pipe section to the starting collar:
•  Lanced pipe end of the starting collar.
•  Inner pipe over inner collar.
•  Push the pipe section until all lanced tabs snap in place.
•  Lightly tug on pipe to confi rm it has locked.

Assemble Pipe Sections
Per Figure 7.2:
•  Start the inner pipe on the lanced end of section A into 
the fl ared end of section B.
•  Start the outer pipe of section A over the outer pipe of 
section B.
•  Once both vents sections are started, push fi rmly until 
all lanced tabs lock into place.
•  Lightly tug on the pipe to confi rm the tabs have locked.
It is acceptable to use screws no longer than 1/2 in. (13 
mm) to hold outer pipe sections together. If predrilling holes, 
DO NOT penetrate inner pipe.
For 90º and 45º elbows that are changing the vent direction 
from horizontal to vertical, one screw minimum should be 
put in the outer fl ue at the horizontal elbow joint to prevent 
the elbow from rotating. Use screws no longer than 1/2 
in. (13 mm). If predrilling screw holes, DO NOT penetrate 
inner pipe.
Required Commercial, Multi-family (Multi-level exceeding 
two stories), or High-Rise Applications
All outer pipe joints must be sealed with high temperature 
silicone (300º F minimum continuous exposure rating), in-
cluding the slip section that connects directly to the hori-
zontal termination cap. 
•  Apply a bead of silicone sealant (300º F minimum con-
tinuous exposure rating) inside the female outer pipe 
joint prior to joining sections. See Figure 7.1. OR
  Apply a bead of silicone sealant (300º F minimum con-
tinuous exposure rating) to the outside of connecting 
joint after joining sections OR
  Apply aluminum foil tape (300º F minimum continuous 
exposure rating) to the outside of connecting joint after 
joining sections. On horizontal pipe runs, it is recom-
mended that the tape seam is positioned on the bottom 
side of the vent pipe.
•  Only outer pipes need to be sealed. All unit collar, pipe, 
slip section, elbow and cap outer fl ues shall be sealed 
in this manner, unless otherwise stated.
WARNING! Risk of Fire or Explosion! DO NOT break 
silicone seals on slip sections. Use care when remov-
ing termination cap from slip pipe. If slip section seals 
are broken during removal of the termination cap, vent 
could leak.

Note: Make sure that the seams are not aligned to prevent 
unintentional disconnection.
