2. Check the Power (120V 60Hz)
Ensure the water heater is connected to a properly rated power supply.
3. Check the Cold Water Inlet Valve
Ensure the cold water inlet valve is open when operating the water heater. The water heater will be damaged if it is not full of
water when operating. Such damages ARE NOT covered by product warranty..
4. Check the Gas Valve
Ensure the manual shut-off gas valve is open. The water heater will not operate unless it is supplied with gas.
5. Check the Area around the Water heater
Remove any combustible or flammable materials from the area around the water heater and do not hang wet laundry from the
exhaust vent pipe.
Do not operate the water heater if its combustion air intake is located in or near one of the areas or in the vicinity of products listed in
Table 1. These areas will always contain hazardous contaminates that can form strong acids while passing through the burner and vent
system. These acids will corrode the water heater’s heat exchanger, burner components and vent system, resulting in flue gas spillage
and/or water leakage, possible substantial property damage, severe personal injury, or death. If the water heater combustion air intake
is located in any area likely to cause or contain contamination, or if products which would contaminate the air cannot be removed, the
intake must be re-piped and terminated to another location.
DO NOT re-pipe ventilation system on your own. Call a qualified service provider for assistance.
AREAS LIKELY TO HAVE CONTAMINANTS
Spray cans containing fluorocarbons
Dry cleaning/laundry areas and establishments
Chlorinated waxes/cleaners
Chlorine-based swimming pool chemicals
Calcium chloride used for thawing
Refrigeration repair shops
Sodium chloride used for water softening
Paint or varnish removers
Plastic manufacturing plants
Hydrochloric or Muriatic acid
Furniture refinishing areas and establishments
New building construction
Antistatic fabric softeners used in clothes dryers
Chlorine-type bleaches, laundry detergents, and cleaning solvents
Adhesives used to fasten building products

B. DURING OPERATION
1. Check for Gas Leaks
Frequently check the gas pipe and connections for leaks with a
soapy solution. If air bubbles appear during the test, gas is leaking
out. Close the gas supply valve and call your gas supplier for
inspection.
After any repair of the gas pipeline or replacement of the gas regulator, call a
qualified service technician to observe the installation and replacement
before restoring power to the water heater. Failure to do so could result in a
fire or explosion, substantial property damage, severe personal injury, or
death.
2. Check for Proper Ventilation
Ensure there is sufficient ventilation while operating the water heater.
Improper ventilation could result in premature water heater failure.
Such failures ARE NOT covered by water heater warranty.
