Sediment Traps/Dirt Leg; High Altitude Installation - Kenmore 153.331350 Use & Care Manual

Fire and Explosion Hazard
• Use joint compound or tape
compatible with natural gas
and propane.
• Leak test before operating
heater.
• Disconnect gas piping and
shut-off valve before pressure
testing system.
Use pipe joint compound or Teflon tape marked as
being resistant to the action of gases.
The appliance and its gas connection must be leak
tested before placing the appliance in operation.
The appliance and its individual shut-off valve
should be disconnected from the gas supply piping
system during any pressure testing of that system
at test pressures in excess of 1/2 psi (3.5kPa).
It should be isolated from the gas supply piping
system by closing its individual manual shut-off
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less
than 1/2 psi (3.5kPa).
Sediment Traps/Dirt Leg
Fire and Explosion Hazard
• Contaminants in gas lines can
cause fire or explosion.
• Clean all gas piping before
installation.
• Install sediment trap (dirt leg)
in accordance with NFPA54.
A sediment trap should be installed as close to the
inlet of the water heater as practical at the time of
water heater installation. The sediment trap should
be either a tee fitting with a capped nipple in the
bottom outlet or other device recognized as an
effective sediment trap. If a tee fitting is used, it
should be installed in conformance with one of the
methods of installation shown in Figures 13 and 14.
Contaminants in the gas lines may cause improper
operation of the gas control valve/thermostat that
may result in fire or explosion. Before attaching
the gas line be sure that all gas pipe is clean on
the inside. To trap any dirt or foreign material in the
gas supply line, a sediment trap (sometimes called
a dirt leg) must be incorporated in the piping. The
sediment trap must be readily accessible. Install in
accordance with the "Gas Piping" section. Refer to
the current edition of the National Fuel Gas Code
(ANSI Z223.1/NFPA 5 4).
High Altitude Installation
Breathing Hazard - Carbon Monoxide Gas
• For operation above 10,100 ft.
(3,048 metres) a high altitude
orifice must be installed.
• Contact a qualified installer or
service agency.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
This heater is approved for operation up to 10,100
feet (3,079 m) without alteration.
Failure to replace standard orifice with a high
altitude orifice when installed above 10,100 feet
(3,079 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 gas
supplier for any specific changes which may be
required in your area.
