VENTING - HORIZONTALLY USING SIMPSON DURA-VENT DIRECT VENT SYSTEMS
1. Set the Optima 72 in its desired location.
Determine if wall studs or roof rafters
are in the way when venting system is
attached. You may want to adjust the
location of the unit to compensate.
2. Simpson Dura-Vent Venting System is
designed with special twist-lock connec-
tions to connect to the appliance. An
Archgard adaptor (999-DV-SDA) is re-
quired. The adaptor will allow Simpson
Dura-Vent System to be used.
3. Apply a bead of sealant inside the outer
section of the 999-DV-SDA adaptor. Slip
the adaptor over the existing inner and
outer flue collar and fasten it to the outer
collar only with 3 screws (drill pilot holes
first). Level the appliance and fasten it to
the framing using nails or screws
through the nailing strips.
4. Assemble the desired combination of
pipe and elbows to the appliance adap-
tor and twist lock the pipe.
NOTE: Twist-lock procedure: Four inden-
tations, located on the female ends of the
pipes and fittings, are designed to slide
straight onto the male ends of adjacent
pipes and fittings by orientating the four
pipe indentations so they match and slide
in to the four entry slots on the male ends
(Fig. 2.). Push the pipe sections com-
pletely together, then twist-lock one sec-
tion clockwise approximately one quarter
turn, until the two sections are fully locked.
The female locking lugs will not be visible
from the outside, on the pipe or fittings.
They may be located by examining the
inside of the female ends. Horizontal vent
runs MUST be supported every three feet
(76 mm). Wall straps are available for this
purpose.
NOTE: Follow venting horizontal venting
chart and Allowable Termination locations
guidelines.
