OWNER’S MANUAL
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
19 and 20). Snorkel kit SVKBK is also
available (see page 17). Follow the same
installation 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 20). 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 fittings. (All connec-
tions must be sealed with high tempera-
ture silicone sealant as specified in the sec-
ond warning statement on page 10.) Push
the pipe sections together and twist one sec-
tion clockwise approximately one-quarter
turn until the sections are fully locked. See
Figure 21, page 12.
Note: Horizontal runs
of vent must be supported every three feet.
Use wall straps for this purpose.
