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).
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.
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.
