Installation & Operation Manual
3 General venting (continued)
6.Priming and Cementing:
a.Handle fittings and pipes carefully to prevent contamination of surfaces.
b.Apply a liberal even coat of primer to the fitting socket.
c.Apply a liberal even coat of primer to the pipe end to approximately 1/2" beyond the socket depth.
d.Apply a second primer coat to the fitting socket.
e.While primer is still wet, apply an even coat of approved cement to the pipe equal to the depth of the fitting socket.
Table 3A Vent Pipe, and Fittings
f.While primer is still wet, apply an even coat of approved cement to the fitting socket.
g.Apply a second coat of cement to the pipe.
h.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.
i.Wipe excess cement from the joint removing ring or beads as it will needlessly soften the pipe.
All vent pipe materials and fittings must comply with the following:
