• 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
DVP Series Venting Only
Attach the fi rst vent components to the starting collar. At-
tach the slip section (cyclone-12 slip) onto the glass cylin-
der (see Figure 8.1).
The next section of pipe slips into the slip section and
must have an overlap of 1-1/2 inch but no more than 6
inches, to allow the slip section room to slide up for glass
removal.
The fi rst section of pipe must be secured to the framing
to make it rigid and allow it to support the remaining pipe
sections.
Figure 8.1
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 Figure 8.4) and the seams are not aligned (see Fig-
ure 8.5). Tug slightly on section A to confi rm it has com-
pletely locked into place.
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.

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 high temperature silicone, including the
slip section that connects directly to the horizontal termina-
tion cap, but not including the CYCLONE-12SLIP.
• 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
Note: The end of the pipe sections with the lances/tabs on
it will face toward the appliance.
Note: It is critical that the relationship of the DVP pipe, Cy-
clone-12SLIP and glass asembly is installed per specifi cation
shown in Figure 8.1. The Cyclone-12SLIP section MUST be
able to be manipulated up and down to ensure routine main-
tenance to the fi replace can be performed.
Do not mix pipe, fi ttings or joining
methods from different manufacturers.
