• 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.
A. Assembly of Vent Sections

Installing Vent Pipe
Attaching Vent to the Firebox Assembly
To attach the fi rst pipe section to the collars, slide the male
end of the inner vent of the pipe section over the inner collar
on the fi rebox assembly. At the same time, slide the outer
fl ue over the outer collar on the appliance. Push the pipe
section into the appliance collar until all the lances (see
Figure 8.2) have snapped in place. Tug slightly on the sec-
tion to confi rm it has completely locked into place.
Make sure that the fi berglass rope ring supplied in the
manual bag seals between the fi rst vent component and
the outer appliance wrap (see Figure 8.1)

WARNING
Assembling Pipe Sections
Insert the inner fl ue of section A into the fl ared inner fl ue of
section B.
Start the outer fl ue of section A over the outer fl ue 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 fl ues are started, press section A onto
section B fi rmly until all lances have snapped into place.
Check to make sure they have snapped together (see Fig-
ure 8.4) and the seams are not aligned (see Figure 8.5).
Tug slightly on section A to confi 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 fl ue 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.
Commercial, Multi-family (Multi-level exceeding two
stories), & High-Rise Applications
For Installation into Commercial, multi-family (multi-level ex-
ceeding two stories) or high-rise applications: All pipe joints
must be sealed with silicone with a minimum of 300ºF contin-
uous exposure rating, including the slip section that connects
directly to the horizontal termination cap.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. See Figure 8.2
• Only outer pipes are sealed. Do not seal the inner fl ue.
All unit collar, pipe, slip section, elbow and cap outer fl ues
shall be sealed in this manner, unless otherwise stated.
Fire Risk
Explosion Risk
If slip section seals are broken during the
removal of the termination cap, gas will leak and
a fi re or explosion may occur.
Do not break silicone seals on slip sections.
WARNING
High Temperature Silicone Sealant
Commercial, Multi-family (multi-level exceeding two
stories), or High-rise Applications only Note: The end of the pipe sections with the lances/tabs on
it will face toward the appliance.
Do not mix pipe, fi ttings or joining
methods from different manufacturers.
