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.
Snorkel terminations are available for terminations
requiring a vertical rise on the exterior of the
building. The gures follow the same installation
procedures used for standard horizontal
terminations. If installing the snorkel termination
below grade (basement applications), you must
provide proper drainage to prevent water from
entering the snorkel termination. Do not back ll
around the snorkel termination.

2. Rigid vent pipes and ttings have special
twist-lock connections. Assemble the desired
combination of pipe and elbows to the
appliance adaptor with pipe seams oriented
towards the wall or oor. Twist-lock Procedure:
The female ends of the pipes and ttings have
three locking lugs (indentations). These lugs will
slide straight into matching slots on the male
end of adjacent pipes and ttings. Push the
pipe sections together and twist one section
clockwise approximately one-quarter turn until
the sections are fully locked. NOTE: Horizontal
runs of vent pipe must be supported every
three (3) feet (914 mm). Use wall straps for this
purpose.

3. Attach vent pipe assembly to the stove. Set
stove in front of its permanent location to
ensure minimum clearances. Mark the wall for a
