Ruud AP14236 installation instructions Cementing Joints, Installing the water heater

Installing the water heater.

NOTICE: All pipe, fittings, solvent cement, primers and procedures must conform to American National Standards Institute and American Society for Testing and Materials (ANSI/ASTM) standards.

WARNING: DANGER OF FIRE OR BODILY INJURY - Solvent cements and primers are highly flammable. Provide adequate ventilation and do not assemble near heat source or open flame. Do not smoke. Avoid skin or eye contact. Observe all cautions and warnings on material containers.

CAUTION:

For proper installation:

DO NOT use solvent cement that has become curdled, lumpy or thickened.

DO NOT thin solvent cement. Observe shelf precautions printed on the containers.

For applications below 32°F use only low temperature type solvent cement.

Appropriate solvent and cleaner must be used for the type of vent pipe used (PVC, CPVC or ABS).

Cementing Joints

All joints in the vent piping must be properly sealed and the following materials are recommended:

PVC materials should use ASTM D2564 grade cement.

CPVC materials should use ASTM F493 grade cement.

ABS materials should use ASTM D2235 grade cement.

Cleaner-Primer and Medium Body Solvent Cement:

Cut pipe end square, remove jagged edges and burrs. Chamfer end of pipe, then clean fitting socket and pipe joint area of all dirt, grease or moisture.

After checking pipe and socket for proper fit, wipe socket and pipe with cleaner-primer. Apply a liberal coat of primer to inside surface of socket and outside of pipe. Do not allow primer to dry before applying cement.

Apply a thin coat of cement evenly in the socket. Quickly apply a heavy coat of cement to the pipe end and insert pipe into fitting with a slight twisting motion until it bottoms out.

NOTICE: Cement must be fluid; if not, recoat.

Hold the pipe fitting for 30 seconds to prevent the tapered socket from pushing the pipe out of the fitting.

Wipe all excess cement from the joint with a rag. Allow 15 minutes before handling. Cure time will vary according to fit, temperature and humidity.

NOTICE: Stir the solvent cement frequently while using. Use a natural bristle brush or the dauber supplied with the can. The proper brush size is one inch.

NOTICE: This unit is equipped with a Flammable Vapor Sensor. Do not apply power until enough time has passed to allow the vapors from the primer and cement to dissipate.
