INSTALLATION FOR
HORIZONTAL TERMINATION
1. Determine the route your horizontal
venting will take. Note: The location
of the horizontal vent termination on the
exterior wall must meet all local and
national building codes and must not be
easily blocked or obstructed.
WARNING: Do not recess vent
terminal into a wall or siding.
Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of the building (see Figures
9 and 10). Snorkel kit CSVK is also
available (see page 15). Follow the
same installation procedures as used for
standard horizontal terminations. If in-
stalling the snorkel termination below
grade (basement applications), you must
provide proper drainage to prevent wa-
ter from entering the snorkel termina-
tion (see Figure 10). Do not back fill
around the snorkel termination.
2. Rigid vent pipes and fittings have spe-
cial twist-lock connections. Assemble
the desired combination of pipe and el-
bows to the appliance adaptor with pipe
seams oriented towards the wall or floor.
Twist-lock Procedure: The female
ends of the pipes and fittings have four
locking lugs (indentations). These lugs
will slide straight into matching slots on
the male ends of adjacent pipes and fit-
tings. (All connections must be sealed
with high temperature silicone sealant
as specified in the second warning state-
ment on page 7.) Push the pipe sections
together and twist one section clockwise
approximately one-quarter turn until the
sections are fully locked. See Figure 11,
page 9. Note: Horizontal runs of vent
must be supported every three feet. Use
wall straps for this purpose.
Flexible vent pipe must be installed with
spacer springs every 12". See Figure 11,
page 9. All connections must be clamped
tightly and sealed with high temperature
silicone sealant as specified in the sec-
ond warning statement on page 7.
