HORIZONTAL INSTALLATION
Step 1. Set the gas stove in its desired location. Check to determine if wall studs or roof rafters
are in the way when the venting system is attached. If this is the case, you may want to
adjust the location of the stove.
Step 2. Simpson Dura-Vent pipe is designed with special twist-lock connections. To connect the
venting system to the stove flue outlet, a twist-lock adapter is built into the stove at the
factory. Assemble the desired combination of pipe and elbows to the adapter with pipe
seams oriented towards the wall or floor, as much out of view as possible. Remember to
include wall thickness in minimum clearances when figuring the measurements for your
installation needs.
Note: Twist-lock procedure: Four indentations, located on the female ends of pipes and fittings,
are designed to slide straight onto the male ends of adjacent pipes and fittings by orienting
the four pipe indentations so they match and slide into the four entry slots on the male
ends (Figure 5). 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.
NOTE: Horizontal runs of vent must be supported every 3 (914mm). Wall straps are available
for this purpose.
