PART 2 – SAFETY REGULATIONS
A. OPERATION AND INSTALLATION WARNINGS
To avoid serious injury or death, read, understand, and follow all the precautions listed here.
Vapors from flammable liquids will explode and can cause a fire, 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 flammable 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 fire or low fire
adjustments, CO levels must be monitored using a flue gas analyzer such that a CO level of no more than 150 ppm is exceeded at any
time during operation.
Adjusting the “low fire offset” or the “main flow restrictor” in small increments can result in a significant 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 flue gas analyzer.
This water heater must be installed by a licensed plumber, licensed gas fitter, 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.
Westinghouse 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 fire, overheating, flood, physical damage, or any other damaging condition that might affect the operation of
the unit. Have the water heater checked by a qualified technician before resuming operation.
Do not power up the unit unless the gas and water supply valves are fully opened. Make sure the fresh air intake port and exhaust gas
port are open and functional.
No one but a professional service technician should attempt to install, service, or repair this water heater. There are no serviceable
parts which can be changed by the user / owner. User / Owner: Contact the original professional service technician if the water heater
needs repair or maintenance. If the original technician is unavailable, ask your gas supplier for a list of qualified service providers.
Keep the area around the water heater clean and free of all materials that can burn. DO NOT store or place gasoline, oils, spray paint,
or other flammable products near the water heater.
DO NOT use spray paint, hair spray, or any other flammable spray near the water heater or near the exterior fresh air intake port. DO
NOT place any items in or around the exterior exhaust gas outlet port and/or fresh air inlet port that could restrict or block the flow in or
out of the vent system.
DO NOT store or place newspapers, laundry, or other combustible items near the water heater or the exterior exhaust gas outlet and/or
fresh air inlet port.
The owner should inspect the system monthly for damage, water stains, signs of rust, corrosion, and exhaust vent and air intake
blockage. If inspection of the unit shows signs of damage, the water heater should be shut off until the problem is repaired by a
qualified technician.
After installation, all water heater safety devices should be tested.
This water heater is certified for indoor installations only. The water heater consists of gas ignition system components which must be
protected from water (dripping, spraying, etc.) during operation and service. Carefully consider installation location and the placement of
critical components (circulators, condensate neutralizers, etc.) before installing the water heater.
DO NOT allow children to operate this unit. DO NOT use this unit if it does not appear to be operating correctly. A qualified technician
should service and inspect the water heater annually.
The water heater temperature is factory set to 125
o
F (51.7
o
C). To avoid scalding, always check the temperature of the hot water before
bathing, showering, washing, etc. DO NOT adjust the water temperature while the water heater is being used by other persons.
