VENTING INSTALLATION
Continued
2. Rigid vent pipes and fittings have special
twist-lock connections. Assemble desired
combination of pipe and elbows to appli-
ance adaptor with pipe seams oriented
towards wall or floor.
Twist-lock Procedure:
Female ends
of pipes and fittings have four locking
lugs (indentations). These lugs will slide
straight into matching slots on male ends
of adjacent pipes and fittings. Push pipe
sections together and twist one section
clockwise approximately one-quarter turn
until sections are fully locked. See Figure
17, page 15.
Note: Horizontal runs of vent
must be supported every three feet. Use
wall straps for this purpose.
3. Attach vent pipe assembly to fireplace us
-
ing twist lock connections for rigid pipe or
clamp method for flex pipe. Set fireplace
in front of its permanent location to insure
minimum clearances. Mark wall for a 10

square hole (for noncombustible material
such as masonry block or concrete, a 8

diameter hole is acceptable). See Figure
18, page 15. The center of hole should line
up with center line of rigid vent pipe. Cut a

Adequate
Drainage
provide a minimum of 1 foot of vertical rise for
every 3 feet of horizontal run. The maximum
horizontal run is 20' with 8' vertical rise (see
Installation for Horizontal Termination
). The
maximum vertical run is 30' (see
Installation
for Vertical Termination
, page 17).
Installing Vent System in a Chase
A chase is a vertical box-like structure built to
enclose venting that runs along the outside
of a building.
NOTICE: Treatment of firestops
and construction of the chase may
vary from building type to building
type. These instructions are not
substitutes for the requirements
of local building codes. You must
follow all local building codes.
Note: When installing in a chase, you should
insulate the chase as you would the outside
walls of your home. This is especially im-
portant in cold climates. Minimum clearance
between vent pipes and combustible materials
such as insulation is 1".
After framing chase (see
Framing
on page
8) install vent system by following installation
instructions.
INSTALLATION FOR HORIZONTAL
TERMINATION
1. Determine the route your horizontal vent
-
ing will take.
Note: The location of horizon-
tal vent termination on exterior wall must
meet all local and national building codes
and must not be blocked or obstructed.
WARNING: Do not recess
vent terminal into a wall or sid-
ing. This is a fire hazard.
Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of building (see Figures 15 and
16). Snorkel kits are available for rigid pipe
applications only to provide a 14" rise and
a 36" rise (see page 21). Follow the same
installation procedures used for standard
horizontal terminations. If installing snorkel
termination to raise vent termination from
below grade level such as in a basement
installation, you must provide proper drain-
age to prevent water from entering snorkel
termination (see Figure 16). Do not back
fill around snorkel termination.
