unintentional disconnection.
ASSEMBLE SLIP SECTIONS
The outer flue of the slip section should slide over the outer
flue of the pipe section and into (inner flue) the last pipe
section (see Figure 23).
Slide together to the desired length, making sure that a
11⁄2" outer flue overlap is maintained between the pipe
section and slip section.
The pipe and slip section need to be secured by driving
two 1/2 in. screws through the overlapping portions of the
outer flues using the pilot holes (see Figure 24).
This will secure the slip section to the desired length and
prevent it from separating. The slip section can then be
attached to the next pipe section.
If the slip section is too long, the inner and outer flues of
the slip section can be cut to the desired length.

SECURE THE VENT SECTIONS
Vertical sections of SLP pipe must be supported every 8 ft.
The SLP firestop includes tabs that may be used to secure
vertical sections.
The vent support or plumber’s strap (spaced 120° apart)
may be used to secure the vertical sections of pipe (see
Figure 25).
Horizontal sections of vent must be supported every 5 ft
with a vent support or plumber’s strap (see Figure 26).

WARNING
Risk of Fire/Explosion/Asphyxiation! Improper support
may allow vent to sag and separate. Use vent run
supports and connect vent sections per installation
instructions. DO NOT allow vent to sag below connection
point to appliance.
WARNING
Risk of Fire/Explosion!
DO NOT
break seals on slip
sections. Use care when removing termination cap from
slip pipe. If slip section seals are broken during removal
of the termination cap, vent may leak.
