VENT PIPE INSTALLATION
AWARNING
Make sure the gassupplied is the same type listed on the
model rating plate. The inlet gaspressuremust not exceed
10.5in. water column (2.6kPa)for natural gasor 13in. water
column (3.2kPa) for propane (L.P.)gas.The minimum inlet
gaspressurelistedon the model rating plate is for the pur-
poseof input adjustment.
AWARNING ,
If the gascontrolvalveis subjected to pressures exceeding'A
poundper squareinch(3.5kPa), the damage to the gascon-
trol valvecouldresult in a fire or explosion from leakinggas.
_WARNING
If the main gasline shutoffservingall gasappliances isused,
alsoturn "OFF" the gasat eachappliance. Leaveall gasappli.
ancesshutoff untilthe water heater installation iscomplete.
There must be a minimum of 6" clearance between single wall
vent pipe and any combustible material. Fill and seal any clear-
ance between single wall vent pipe and combustible material
with mortar mix, cement, or other noncombustible substance.
For other than single wall, follow vent pipe manufacturer's clear-
ance specifications. To insure a tight fit of the vent pipe in a
brick chimney, seal around the vent pipe with mortar mix
cement.
AWARNING
Failureto haverequired clearancesbetween vent pipingand
combustible material will result in a fire hazard.

A gas line of sufficient size must be run to the water heater.
Consult the latest edition of National Fuel Gas Code ANSI
Z223.1, also referred to as NFPA 54 and the gas company con-
cerning pipe size.
There must be:
• A readily accessible manual shut offvalve in the gas supply llne
serving the water heater, and
• A drip leg (sediment trap) ahead of the gas control 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
shutoffvalve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lil_hting the
water heater. Use a soapy water solution, not a match or open
flame. Rinse offsoapy solution and wipe dry.
Standard Models are for installation up to 3,300 feet above sea
level.
High Altitude Models are for installation from 3,300 to 5,500
feet above sea level.
If a standard model is installed above 3,300 feet or a high altitude
model is installed above 5,500 feet, the input rating must he
reduced at the rate of 4 percent for each 1,000 feet above sea level.
Contact your local Sears Service Center or gas utility for further
information.
