Gas Supply; Gas Requirements; Gas Piping; Gas Pressure - Kenmore ELITE 153.33262 Use And Care Manual

Explosion Hazard
• Use a new CSA approved gas supply line.
• Install a shut-off valve.
• Do not connect a natural gas water heater to an L.P. gas
supply.
• Do not connect an L.P. gas water heater to a natural gas
supply.
• Failure to follow these instructions can result in death,
explosion, or carbon monoxide poisoning.
Gas Requirements
IMPORTANT: Read the rating plate to be sure the water heater
is made for the type of gas you wilt be using in your home. This
information wilt be found on the rating plate located near the gas
control valve/thermostat. If the information does not agree with
the type of gas available, do not install or light. Call your dealer.
NOTE: An odorant is added by the gas supplier to the gas used
by this water heater. This odorant may fade over an extended
period of time. Do not depend upon this odorant as an indication
of leaking gas.
Gas Piping
The gas piping must be installed according to all local and state
codes or, in the absence of local and state codes, the "National
Fuel Gas Code", ANSI Z223.1(NFPA 54)-current edition.
Tables 1 and 2 on the following page provide a sizing reference for
commonly used gas pipe materials. Consult the "National Fuel Gas
Code" for the recommended gas pipe size of other materials.
NOTE: Use pipe joint compound or teflon tape marked as being
resistant to the action of petroleum gases (See Figure 12.)
1. Install a readily accessible manual shut-off valve in the gas
supply line as recommended by the local utility. Know the
location of this valve and how to turn off the gas to this unit.
2. Install a drip leg (if not already incorporated as part of
the water heater) as shown. The drip leg must be no tess
than three inches tong for the accumulation of dirt, foreign
material, and water droplets.
3. Install a ground joint union between the gas control valve/
thermostat and the manual shut-off valve. This is to allow
easy removal of the gas control valve/thermostat.
4. Turn the gas supply on and check for leaks. Test all
connections by brushing on an approved noncorrosive leak-
detection solution. Bubbles will show a leak. Correct any
leak found.
Gas Pressure
FIGURE 12.
Explosion Hazard
• Gas leaks can not always be detected by smell.
• Gas suppliers recommend that you use a gas
detector approved by UL or CSA.
• For more information, contact your gas supplier.
• If a gas leak is detected, follow the "What to do if you
smell gas" instructions on the cover of this manual.
IMPORTANT: The gas supply pressure must not exceed the maximum
supply pressure as stated on the water heater's rating plate. The
minimum supply pressure is for the purpose of input adjustment.
Gas Pressure Testing
IMPORTANT: This water heater and its gas connection must be leak
tested before placing the appliance in operation.
• If the code requires the gas lines to be tested at a pressure
exceeding 14" W.C., the water heater and its manual shut-off
valve must be disconnected from the gas supply piping system
and the line capped.
• If the gas lines are to be tested at a pressure tess than 14" W.C.,
the water heater must be isolated from the gas supply piping
system by closing its manual shut-off valve.
NOTE: Air may be present in the gas lines and could prevent the
burner from lighting on initial start-up. The gas lines should be purged
of air by a qualified technician after installation of the gas piping
system. While purging the gas piping system of air, insure that the
fuel is not spilled in the area of the water heater installation, or
any source of ignition (NOTE: spilled fuel may trip the FV Sensor
preventing heater from starting). If the fuel is spilled while
purging the piping system of air follow the "WHAT TO DO IF YOU
SMELL GAS" instructions on the cover of this manual.
