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 Z223.1IN FPA 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
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.

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.
