Rheem Commercial Power Direct Vent Water heater Installation Check List, For Proper Installation

FOR PROPER INSTALLATION:

!CAUTION

•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).

Avoid skin or eye contact. Observe all cautions and warnings on material containers.

6.WIRING — A polarized 120V 50/60 Hz power supply, with suitable disconnect means, must be connected to the black and white leads provided. The current draw by the Power Direct Vent unit is 1.5 Amps. The water heater, when installed, must be electrically grounded in ac- cordance with local codes, or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 in the United States; or CSA C22.1 Electrical Code, in Canada. Refer to Fig. 14 on page 26 & 27 of this manual for water heater internal wiring diagrams.

NOTICE: DO NOT use in conjunction with a GFCI.

!WARNING

DANGER OF FIRE OR BODILY INJURY – Solvent cements and primers are highly flammable. Pro- vide adequate ventilation and do not assemble near heat source or open flame. Do not smoke.
