Prepare condensate fittings
1.Remove PVC fittings and gasket from the accessories bag.
2.Deburr and chamfer outside and inside of ½" x 1¼" PVC nipple to ensure even cement distribution when joining.
3.Clean nipple ends and all fittings. Dry thoroughly.
4.For each joint in the condensate line, apply the following. Assemble parts ONLY in the order given.
a.Apply primer liberally to both joint surfaces — pipe end and fitting socket.
b.While primer is still damp, lightly apply approved cement to both surfaces in a uniform coating.
Figure 11 Condensate trap assembly
c.Apply a second coat of cement to both surfaces. Avoid using too much cement on sockets to prevent cement buildup inside.
d.With cement still wet, insert pipe into fitting, twisting ¼ turn. Make sure pipe is fully inserted.
e.Wipe excess cement from joint. Check joint to be sure a smooth bead of cement shows around the entire joint.
5.See Figure 11.
6.Assemble the ½" PVC nipple to the PVC reducing elbow as shown.
7.Allow joint to dry completely. Then slide gasket over nipple as shown.
8.Slide nipple through jacket condensate line hole to position as shown in Figure 13, page 20.
9.Cement the ½" tee to the protruding ½" nipple. Be sure both nipple and reducing elbow finish upright. IMPORTANT: Firmly press the reducing elbow and the tee together while the cement sets to ensure the gasket is securely compressed. The gasket ensures the jacket enclosure is airtight at this location.
