The minimum inlet gas pressure shown on the rating plate is
that which will permit firing at the rated input.
Breathing Hazard - Carbon Monoxide Gas
• High altitude orifice must be installed
for operation above 3,300 ft. (1,006 m)
or 5,500 ft (1,676 m) for a high altitude
models.
m " Contact a qualified installer or service
agency.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
If a standard model is installed above 3,300 feet (1,006 m) or a
high altitude model is installed above 5,500 feet (1,676 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 3,300 feet (1,006 m) or
above 5,500 feet (1,676 m) for high altitude model) 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 Explosion Hazard
• Use joint compound or tape
corn patible with 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 petroleum (Propane [LP.]) gases.
The appliance and its gas connection must be leak tested
before placing the appliance in operation.
The appliance and its individual shutoff valve shall be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 pound per square inch (3.5kPa). It shall be isolated from
the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2 pound
per square inch (3.5kPa).
Connecting the gas piping to the gas control valve of the water
heater can be accomplished by either of the two methods
shown in Figures 19 and 20.
Sediment Traps
Fire and
Explosion
Hazard
• Contaminants in gas lines can
cause fire or explosion.
• Clean all gas piping before
installation.
• Install drip leg in accordance
with NFPA 54.
16
Contaminants in the gas lines may cause improper operation
of the gas control valve 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 drip leg (sometimes called a sediment trap)
must be incorporated in the piping. The drip leg must be readily
accessible. Install in accordance with the Gas Piping section.
