Gas Piping - Kenmore 153.338071 Owner's Manual

Breathing Hazard o Carbon Monoxide Gas
, Flue gases may escape if vent
pipe is not connected.
• Do not store corrosive chemicals
in vicinity of water heater.
• Chemical corrosion of flue and
vent system can cause serious
injury or death.
• Contact a qualified installer or
service agency.
Breathing carbon monoxide can cause brain damage
or death. Always read and understand instruction manual.
There must be:
A readily accessible manual shut off valve in the gas supply
line serving the water heater, and
A drip leg (sediment trap) ahead of the gas contro! valve to
help prevent dirt and foreign materials from entering the
gas control valve.
A flexible gas connector or a ground joint union between the
shut off valve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting the
water heater. Use a soapy water solution, not a match or open
flame. Rinse off soapy solution and wipe dry.
The minimum inlet gas pressure shown on the rating plate is
that which will permit firing at the rated input.
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.
Gas Piping
Fire and Explosion Hazard
Do not use water heater with
any gas other than the gas
shown on the rating plate,
Excessive pressure to gas
control valve can cause serious
in}ury or death
Turn off gas lines during
installation
Contact qualified installer or
service agency.
Make sure the gas supplied is the same type listed on the
model rating plate. The inlet gas pressure must not exceed
14 inch water column (3.SkPa) for natural gas. The minimum
inlet gas pressure listed on the rating plate is for the purpose
of input adjustment, if the gas control valve is subjected to
pressures exceeding 1/2 pound per square inch (3.SkPa), the
damage to the gas control valve could result in a fire or explosion
from leaking gas.
if the main gas line shut-off serving eli gas appliances is used,
also turn "OFF" the gas at each appliance. Leave alI gas
appliances shut "OFF" until the water heater installation is
complete.
A gas line of sufficient size must be run to the water heater.
Consult the current edition of National Fuel Gas Code
ANSI Z223.1/NFPA 54 and your gas supplier concerning pipe
size.
Breathing Hazard - Carbon Monoxide Gas
_!:_! , High altitude orifice must be installed
for operations above 2,000 fL (610 m).
_,_ _ • Contact a qualified insta,ier or serv,ee
P
_ss"'" _ agency.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual
if a standard model is installed above 2,000 feet (610 m) the
input rating should be reduced at the rate of 4 percent for each
1,000 feet (305 m ) above sea level which requires replacement
of the burner orifice in accordance with National Fuel Gas Code
ANSI Z223.1/NFPA 54. Contact your local Sears Service Center
or local gas supplier for further information.
Failure to replace the standard orifice with a high altitude orifice
when installed at elevations above 2,000 feet (610 m) could
result in improper and inefficient operation of the appliance,
producing carbon monoxide gas in excess of safe limits, which
could result in serious injury or death. Contact your local Sears
Service Center or local gas supplier for any specific changes
which may be required in your area.
Fire and E×plosion Hazard
- Use joint compound or tape
compatible with propane.
Leak test before operating
heater
-Disconnect gas piping and
shut-off valve before pressure
testi ng system.
The appliance and its gas connection must be leak tested
before placing the appliance in operation.
