VENTING - HORIZONTALLY USING SIMPSON DURA-VENT DIRECT VENT SYSTEMS
1. Set the Optima 45 in its desired location.
Determine if wall studs or roof rafters are in
the way the 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 connections
to connect to the appliance. An Archgard
adaptor (999-DV-SDA) is required. The
adaptor will allow Simpson Dura-Vent
System to be used.
3. Apply a bead of silicone inside the outer
section of the adaptor (crimped side). 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 adaptor and
twist lock the pipe.
NOTE: Twist-lock procedure: Four
indentations, 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 completely together, then twist-lock
one section 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.
