Polypropylene - Smith XWH 150 Instruction Manual

7. Priming and Cementing:
• Handle fittings and pipes carefully to prevent
contamination of surfaces.
• Apply a liberal even coat of primer to the fitting socket
and to the pipe end to approximately 1/2" beyond the
socket depth.
• Apply a second primer coat to the fitting socket.
• While primer is still wet, apply an even coat of approved
cement to the pipe equal to the depth of the fitting socket
along with an even coat of approved cement to the fitting
socket.
• Apply a second coat of cement to the pipe.
• While the cement is still wet, insert the pipe into the
fitting, if possible twist the pipe a 1/4 turn as you insert
it. NOTE: If voids are present, sufficient cement was not
applied and joint could be defective.
• Wipe excess cement from the joint removing ring or
beads as it will needlessly soften the pipe.

POLYPROPYLENE

This product has been approved for use with the Polypropylene
vent with the manufacturers listed in Table 12.
All terminations must comply with listed options in this manual
and be a single-wall vent offering.
For support and special connections required, see the
manufacturer's instructions. All vent is to conform to standard
diameter and equivalent length requirements established.
When determining equivalent combustion air and vent length for
polypropylene single-wall piping:
• 1 foot of Duravent 4 inch single-wall pipe is equivalent to 1.6
feet of piping.
FLEXIBLE POLYPROPYLENE
For use of flex pipe, it is recommended to have the vent material
in 32°F or higher ambient space before bending at installation.
No bends should be made to greater than 45° and ONLY installed
in vertical or near vertical installations (Figure 19).
