HYDROGEN GAS: Hydrogen gas can be produced in a hot

water system that has not been used for a long period of time

(generally two weeks or more). Hydrogen gas is extremely

flammable and explosive. To prevent the possibility of injury

under these conditions, we recommend the hot water faucet,

located farthest away, be opened for several minutes before

any electrical appliances which are connected to the hot water

system are used (such as a dishwasher or washing machine).

If hydrogen gas is present, there will probably be an unusual

sound similar to air escaping through the pipe as the hot water

faucet is opened. There must be no smoking or open flame

near the faucet at the time it is open.

HIGH WATER TEMPERATURE SHUT OFF SYSTEM

This water heater is equipped with an automatic gas Shut-off

system. This system works when high water temperatures

are present. The high temperature Shut-off is built into the gas

control valve. It is non-resettable. If the high temperature Shut-

off activates, the gas control valve must be replaced. Turn

“OFF” the entire gas supply to the water heater. Contact your

gas supplier or service agency.

VENTING SYSTEM INSPECTION

At least once a year a visual inspection should be made of the

venting system. You should look for:

1. Obstructions which could cause improper venting. The

combustion and ventilation air flow must not be obstructed.

2. Damage or deterioration which could cause improper

venting or leakage of combustion products.

3. Rusted flakes around top of water heater.

Be sure the vent piping is properly connected to prevent escape

of dangerous flue gases which could cause deadly

asphyxiation.

Obstructions and deteriorated vent systems may present

serious health risk or asphyxiation.

Chemical vapor corrosion of the flue and vent system may

occur if air for combustion contains certain chemical vapors.

Spray can propellants, cleaning solvents, refrigerator and air

conditioner refrigerants, swimming pool chemicals, calcium

and sodium chloride, waxes, bleach and process chemicals

are typical compounds which are potentially corrosive.

If after inspection of the vent system you found sooting or

deterioration, something is wrong. Call the local gas utility to

correct the problem and clean or replace the flue and venting

before resuming operation of the water heater.

BURNER INSPECTION

Flood damage to a water heater may not be readily visible or

immediately detectable. However, over a period of time a

flooded water heater will create dangerous conditions

which

can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY

DAMAGE. Contact a qualified installer or service agency to

replace a flooded water heater. Do not attempt to repair the

unit! It must be replaced!

At least once a year a visual inspection should be made of the

main burner and pilot burner, see Figure 33.

You should check for sooting. Soot is not normal and will

impair proper combustion.

Soot build-up indicates a problem that requires correction

before further use. Turn “OFF” gas to water heater and leave

off until repairs are made, because failure to correct the cause

of the sooting can result in a fire causing death, serious injury,

or property damage.
