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.
Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of the building (see Figures
9 and 10). Snorkel kit SVK is also avail-
able (see page 15). Follow the same in-
stallation procedures used for standard
horizontal terminations. If installing the
snorkel termination below grade (base-
ment applications), you must provide
proper drainage to prevent water from
entering the snorkel termination (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.
