Table 3 – Items Included with the Water Heater

▪ A. OPERATION AND INSTALLATION WARNINGS

To avoid serious injury or death, read, understand, and follow all the precautions listed here.

WARNING

This water heater must be installed by a licensed plumber, licensed gas tter, and/or professional service technician. Improper installation and/or

operation can cause a potentially hazardous situation, which, if not avoided, could result in serious injury or death, and will void the warranty.

Rheem cannot anticipate every circumstance that might involve a potential hazard. Each installation has its own specialized characteristics,

requirements, and possible hazards. Therefore, all possible incidents are not included in these warnings. Proper and safe installation, operation,

and service are the responsibility of the professional service technician.

Proper care of the water heater is the user’s responsibility. Ensure the user carefully reads and understands the User’s Information Manual before

operating and maintaining the water heater.

Make sure the user knows the location of the gas shut-off valve and how to operate it. Immediately close the gas shut-off valve if the water heater

is subjected to re, overheating, ood, physical damage, or any other damaging condition that might affect the operation of the unit. Have the

water heater checked by a qualied technician before resuming operation.

DANGER

Vapors from ammable liquids will explode and can cause a re, resulting in personal injury or death. The water heater has a burner that can

come on at any time and ignite vapors. DO NOT use or store ammable liquids around the water heater.

Improper venting can cause a build-up of carbon monoxide. Breathing carbon monoxide can result in brain damage or death. DO NOT operate the

water heater unless it is properly vented to the outside and has an adequate fresh air supply for safe operation. Inspect the exterior exhaust gas

outlet port and fresh air inlet port on a regular basis to ensure they are functioning properly.

A concentration of carbon monoxide as small as .04% (400 parts per million) in the air can be fatal. When making high re or low re adjustments,

CO levels must be monitored using a ue gas analyzer such that a CO level of no more than 150 ppm is exceeded at any time during operation.

Adjusting the “low re offset” or the “main ow restrictor” in small increments can result in a signicant increase in CO concentration. To avoid

serious injury or death, DO NOT make any adjustments to the gas valve without monitoring the exhaust gases with a fully functional and calibrated

ue gas analyzer.
