Safety Precautions - American Standard 75-76 AS Operating, Installation And Service Manual

OPERATION

Safety precautions:

DO turn off heater if it has been subjected to physical damage,
flooding, or fire.
DO NOT turn on heater unless it is filled with water.
DO NOT turn on heater if cold water supply inlet valve is
closed.
DO NOT attempt to light heater until all lighting instructions
are understood and followed. See below and label on heater near
thermostat (Figure 6).
DO NOT allow flammable liquids, such as gasoline or paint
thinner, to be stored or used near heater.
DO NOT allow combustible materials such as newspaper, rags
or mops to accumulate near heater.
WARNING
TO AVOID POSSIBLE INJURY, FIRE AND EXPLOSION.
READ THESE PRECAUTIONS BEFORE ATTEMPTING
TO LIGHT OR RELIGHT THE PILOT. Check the data plate
near the gas control valve thermostat for the correct gas. DO
NOT USE THIS WATER HEATER WITH ANY GAS
OTHER THAN THE ONE LISTED ON THE DATA PLATE
(Figure 6). Failure to use the correct gas can cause problems
which can result in DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE. If you have any questions or
doubts consult your gas supplier or gas company.
CONDENSATION
Whenever the heater is filled with cold water or hot water is
drawn from a faucet there will be a certain amount of
condensation formed while the burner is "ON". Moisture from
the products or combustion condenses on the cooler tank
surfaces and forms drops of water which may fall onto the
burner or other hot surfaces to produce a "sizzling" or "frying"
noise. Condensation is normal and should not be confused
with a leaking tank.
The water from condensation will be noted at different times
of the year in varying quantities. This condensation may spill
out of the collector pan onto the floor. Do not confuse this
with a leak. Once the water inside of the heater reaches a
temperature of 120°F, the condensation will stop. Operating
the water heater at the lowest thermostat temperature setting
can keep the water heater in the condensation mode. Adjusting
the thermostat setting slightly higher will overcome this
problem. There is hot water scald potential however if
thermostat is set too high.
NATURAL GAS MODELS
IF YOU S MELL GAS :
1. Open windows.
2. Get all people out of building.
3. DO NOT light matches. Do not smoke.
4. DO NOT touch electrical switches (on or off).
5. Extinguish any open flames.
6. Shut off gas at manual shut-off valve.
7. Use an outside phone and immediately call the gas com-
pany and the fire department. Ask for instructions. Before
hanging up, give your name and address.
8. DO NOT go back into the building. If help is coming, wait
for it outside of the building.
L.P.G. (PROPANE, BOTTLED)
GAS MODELS
L. P. G. IS HEAVIER THAN AIR
Should there be a leak in the system, the gas will settle at
FLOOR LEVEL. Basements, crawl spaces, skirted areas
under mobile homes (even when ventilated), closets and
areas below ground level will serve as pockets for the ac-
cumulation of gas.
BEFORE LIGHTING SNIFF AT FLOOR LEVEL
IF YOU SMELL GAS, FOLLOW THESE RULES:
1. Open windows.
2. Get all people out of building.
3. DO NOT light matches. Do not smoke.
4. DO NOT touch electrical switches (on or off).
5. Extinguish any open flames.
6. Shut off gas at the L.P. tank outside of the building.
7. Use an outside phone and immediately call the gas com-
pany and the fire department. Ask for instructions. Before
hanging up, give your name and address.
8. DO NOT go back into the building. If help is coming, wait
for it outside of the building.
OUT OF FUEL
When your L.P. tank runs out of fuel, turn off gas at all gas
appliances including gas to pilots. After L.P. tank is refilled,
all appliances must be re-lit according to the manufacturer's
instructions.
WARNING
HYDROGEN GAS
Hydrogen gas can be produced in a water system that has not
been used for a long period of time (generally two weeks or
more). HYDROGEN
FLAMMABLE. To prevent the possibility of injury under
these conditions, we
recommend the hot water faucet be open for several minutes at
the kitchen sink before you use any electrical appliance which
is connected to the hot water system. Do not light a cigarette,
cigar or pipe. Do not smoke. If hydrogen is present, there will
probably be an unusual sound such as air escaping through the
faucet, as the water begins to flow. Remember no smoking or
open flame near the faucet at the time it is opened.
EXPOSURE TO WATER
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.
