IMPORTANT INSTRUCTIONS BEFORE INSTALLATION
1. Be sure installation meets all local plumbing codes.
2. If you are not thoroughly familiar with plumbing and safety practices, consult your local store for
further information.
3. Check the water heater temperature-pressure relief valve for proper operation; replace if found to
be faulty.
WARNING: Explosion Hazard. Temperature-pressure relief valve must comply with
ANSI Z21.22 and ASME code. Overheated water can cause water tank explosion.
Properly sized temperature and pressure relief valve must be installed in opening
provided. Failure to follow these instructions could result in death or serious injury.
When checking the temperature-pressure relief valve operation, make sure that (1) no one is in
front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) the
water manually discharged will not cause any property damage or bodily injury. The water may
be extremely hot.
If the valve fails to completely reset and continues to release water after manual operation,
immediately close the cold water inlet to the water heater, follow draining instructions, and replace
the temperature-pressure relief valve with a new one.
Also read and follow additional information found in the water heater manual concerning the
temperature-pressure relief valve.
