VENT RESTRICTOR
Vent restrictors are required in certain venting applications. This restrictor must be installed
before connecting the vent pipe to vent terminal.
Referring to the figure below, slide the restrictor into the inner flue pipe and bend the side
tabs appropriately to secure the part. Examine the following diagram for further detail.
Figure: 8 - Drawing of venting restrictor and placement.
HORIZONTAL TERMINATION INSTALLATIONS
1. Set the unit in the desired location, this location must satisfy all applicable
codes and regulations. Check to determine if wall studs and roof rafters are
clear of the venting path. Adjust the unit accordingly.
2. Simpson Dura-Vent Direct Vent pipe and fittings are designed with special twist
lock connections for attaching the appliance flue outlet to the venting system.
This special twist lock adapter has been installed on the appliance from the
factory. Assemble the desired combination of pipe and elbows to the appliance
adapter with pipe seams facing towards the wall or ceiling, depending on
application.
Twist Lock Procedure
Four indentations, located on the female ends of the pipes and fittings, are designed
to slide straight into the male ends of adjacent pipes and fittings. Align the four
indentations so that they match the four entry slots on the male ends, and then slide
into slots. Push the pipe sections tightly together, then twist lock one section
clockwise ¼ turn, until a complete lock is achieved.
