GENERAL SAFETY
INFORMATION
PRECAUTIONS
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN UNDER
WATER. Immediately call a qualified service technician to inspect
the appliance and to replace any part of the control system and any
gas control which has been under water.
IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT
OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE BEEN
MADE BY A QUALIFIED SERVICEMAN.
1. EXTERNAL FIRE.
2. DAMAGE.
3. FIRING WITHOUT WATER.
4. SOOTING
LIQUID PETROLEUM MODELS
WARNING
Water heaters for propane or liquified petroleum gas (LPG) are
different from natural gas models. A natural gas heater will not
function safely on LP gas and no attempt should be made to convert
a heater from natural gas to LP gas.
CHEMICAL VAPOR CORROSION
WARNING
CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY
OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN
CHEMICAL VAPORS. SUCH CORROSION MAY RESULT IN
FAILURE AND RISK OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium and
sodium chloride (water softener salt), waxes, and process
chemicals are typical compounds which are potentially corrosive.
Do not store products of this sort near the heater. Also, air which is
brought in contact with the heater should not contain any of these
chemicals. If necessary, uncontaminated air should be obtained
from remote or outside sources. The limited warranty is voided
when failure of the water heater is due to a corrosive atmosphere.
(Refer to the limited warranty for complete terms and conditions.)
IMPROPER COMBUSTION
WARNING
ATTIC AND/OR EXHAUST FANS OPERATING ON THE PREMISES
WITH A WATER HEATER CAN RESULT IN CARBON MONOXIDE
POISONING AND DEATH.
OPERATION OF THESE FANS CAN PRODUCE A NEGATIVE DRAFT
IN THE AREA OF THE WATER HEATER PREVENTING THE
PRODUCTS OF COMBUSTION FROM EXHAUSTING THROUGH
THE CHIMNEY OR VENT PIPE.
The venting of the water heater should be inspected by a qualified
service technician at the time of installation and periodically
thereafter to ensure a down-draft condition does not exist.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND
VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.
EXTENDED NON-USE PERIODS
WARNING
HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER SYSTEM
SERVED BY THIS HEATER THAT HAS NOT BEEN USED FOR A
LONG PERIOD OF TIME (GENERALLY TWO WEEKS OR MORE).
HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the risk
of injury under these conditions, it is recommended that the hot
water faucet be opened for several minutes at the kitchen sink
before using any electrical appliance connected to the hot water
system. If hydrogen is present, there will probably be an unusual
sound such as air escaping through the pipe as the water begins
