PLAN HOW YOU WILL INSTALL YOUR WATER HEATER
TOOLS AND MATERIALS NEEDED
• Copper or galvanized pipe and fittings (3/4" minimum size)
as needed to make the piumbing connections (see FIG. 1,
Page 5 and FIG. 2, Page 6). CPVC plastic pipe and fittings
are permitted in some areas.
• You can buy water heater installation kits
from Sears. The kits Include flexible con­
nectors with 3/4" fittings to help make
installing the water heater easier.
• Pipe thread seal compound.
•
Electrical wiring materials as needed
(see Step 8 and Page 7).
• Pipe wrenches (2), hacksaw or pipe cutter, wire stripper or
knife, a wire cutter, and a Phillips screwdriver. If installing
copper pipe and solder fittings, you will need a propane
torch, lead free solidcore solder (see following Note Ф),
paste flux, emery cloth, sand paper or steel wool. If
installing CPVC plastic, solvent cement is needed.
Ф NOTE: For copper pipe installations, to help guard
against the adding of lead to water supplies, Federal law
prohibits the use of solder containing more than 0,2
percent of lead.
WHERE TO LOCATE THE WATER HEATER
If you are replacing an old water heater, you will probably want
to use the same location. If you want to change the location,
or if this is a new installation, consider the following:
• Locate close to where you will use the most hot water. Less
heat is iost when the hot water has a short distance to flow.
• Locate close to a floor drain, iaundry tub or sink. A proper
(check locai codes) drain is needed for the temperature
and pressure relief drain pipe (see Page 6), and for monthly
draining of the water heater (see Page 10).
• Do not install where water could freeze in the water heater.
Freeze damage voids your warranty from Sears (see Page 12).
• Do not install next to a wood-burning stove or other
appliance where high temperature could warp or otherwise
damage the water heater outer jacket.
• Put the water heater in a place water damage is least likely
if it should start to leak. If needed (see following note @ ) ,
make or buy a suitable drain pan and place it under the
water heater. The drain pan must have a free flowing drain
line to carry away water that may leak into it.
® NOTE: Recommended by American National Standards
Institute (ANSI) Z21-10.1- (latest issue) under instruction
section, if water heater is located in or above an area that
could be damaged by water leaks.
• For ease of service, be sure you are able to get to the drain
valve, temperature and pressure relief vaive, and access
panels to the controls.
• Be sure the floor is level so the water heater will stand
straight.
REMOVE THE OLD WATER HEATER
(if it applies)
1. TURN OFF ELECTRIC POWER TO THE WATER HEATER at
the fuse or circuit breaker panel.
If removing a gas water heater, TURN OFF THE GAS SUPPLY
TO THE HOUSE, disconnect and cap, or remove, the g^ line
to the water heater (check local codes) and the vent pipe.
------------------------- WARNING----------------------------
DO NOT SMOKE, CREATE SPARKS OR USE OPEN
FLAME DURING CAPPING OR REMOVING GAS LINE AS
AN EXPLOSION MIGHT RESULT.
2. Turn off the water supply to the water heater.
