LIMITED WARRANTY ................................................................... 23
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 water heater is due to a corrosive atmosphere. (Refer to
the limited warranty for complete terms and conditions.)
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.
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 to flow.
FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN.
