VENT PIPE INSTALLATION

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 noncorabustible substance.

For other than single wall, follow vent pipe manufacturers 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.

Gas Р1р1щ

awarning

Mai® sure the gas supplied is the same type listed on the

model rating plate. The inlet gas pressure must not exceed

I0«5 in. water column (2.6kPa) for natural gas or 13 in. water

column (3.2kPa) for propane (LR) gas. The minimum inlet

gas pressure listed on the model rating plate is for the pur

pose of input adjustinent

AWARNING

if the gas control valve is subjected to pressures exceeding 'h

pound per square inch (3.SkPa), the dami^ to the gas con

trol valve could result in a fire or oqjfosion from leaking gas.

AWARNING

If the main gas line shutoff serving all gas appliances is used,

also turn “OFF" t^ gas at each appliance. Leat№ all gas appli

ances shut off until the water hei^r installation is complete.

AWARNING

Failure to have required clearances between vent piping and

combustible material will result in a fire hazard.

AWARNING

Be sure vent pipe b properly connected to prevent escape of

dangerous flue gases which could cause deadly asphyxiation.

AWARNING

Chemical vapor corrosion of the flue and vent system may

occur if air for combustion contains certain chemical vapors.

Spi^ can propellants, cleaning solvents, refrigerator and air

conditioner refri^rants, swimming pool chemicals, calcium

and sodium chloride, waxes, bleach, and process chemicals are

typical compounds which are potentially corrosive.

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 rudily accessible manual shut off valve in the gas supply line

serving the water heater, and

• A drip l№ (sediment trap) ahead of the gas control valve to help

prevent dirt and foreign materiab fiom entering the gas control

valve,

• A flexible gas connector or a ground joint union between the

shutoff valve and control valve to permit servicing of the unit.

Be sure to check all the gas piping for leaks befóte lighting the

water h«ter. Use a soapy water solution, not a mattii or open

flame. Rinse off soapy solution and wipe dry.

Standani Models are for installation up to 3,300 feet above sea

level.

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 be

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.

AWARNING

The appliance and its gas connection must be leak tested

before placing the appliance in operation.
