Troubleshooting Guide (cont*d)

Start Up Conditions (cont’d)

CONDENSATION

Whenever the water heater is filled with cold water, a certain

amount of condensation will form while the burner is on. A

water heater may appear to be leaking when in fact the water is

condensation. This usually happens vmen:

• When a new water heater is filled with cold water for the

first time.

• When gas burns and water vapor is produced in water

heaters, particularly high efficiency models where flue tem^

peratures are lower,

• When you use large amounts of hot water in a short time

and the refill water is very cold.

Moisture from the products of combustion condense on the

cooler tank surfaces and form drops of water which may fall

onto the burnet or other hot surfeces to produce a “sizzling” or

“frying” noise.

Excessive condensation can cause pilot outage due to water run

ning down the flue tube onto the main burner and putting out

the pilot.

Because of the suddenness and amount of water, condensation

water may be diagnosed as a “tank leak”. After the water in the

tank warms up (about 1-2 hours), the condition should

disappear.

Do not ^sume the water heater is leaking until there has been

enough time for the water in the tank to warm up.

An undersized water heater will cause more condensation. The

water heater must be sized properly to meet the family’s

demands for hot water including dishwashers, washing machines

and shower heads.

Excessive condensation may be noticed during the winter and

early spring months when incoming water temperatures are at

their lowest.

Good venting is essential for a gas fired water heater to operate

properly as well as to carry away products of combustion and

■ water vapor.

SMOKE/ODOR

It is not uncommon to experience a small amount of smoke and

odor during the initial start-up. This is due to burning off of oil

from metal parts, and will disappear in a short while.

Operational Conditions

SMELLY WATER

In each glasslined water heater there is installed at least one

anode rod (see parts section) for corrosion protection of the

tank. Certain water conditions will cause a reaction between this

rod and the water. The most common complaint associated with

the anode rod is one of a “rotten egg smell”. This odor is derived

from hydrogen sulfide gas dissolved in the water. The smell is

the result of four faaors which must all be present for the odor

to develop:

a. a concencration of sulfate in the supply water,

b. little or no dissolved oxygen in the water.

c. a sulfate reducing bacteria within the water heater. (This

harmless bacteria is non-toxic to humans.)

d. an excess of active hydrogen in the tank. This is caused by

the corrosion protective action of the anode.

Smelly water may be eliminated or reduced in some water heater

j the anode(s) with one of less active material,

and then chlorinating the water heater tank and all hot water

lines. Contact Sears Service for further information concerning

an Anode Replacement Kit #9001453 and this Chlorination

Treatment,

If the smelly water persists after the anode replacement and chlo

rination treatment, we can only suggest that continuous chlori

nation and filtering conditioning equipment be considered to

eliminate the water problem.

Do not remove the anode leaving the tank unprotected. By

doing so, all warranty on the water heater tank ¡$ voided.

awarning

HOTTER WATER CAN SCALD: Wrter heaters are intended to

pn^uce hot water. Water heated to a temperature which will

satisfy dotiies washing, dish washing, and other sanitizing needs

can scald and permanently injure you upon contact Some peo

ple are more likely to be permanently injured by hot water than

others. These indude the elderly, children, the infirm, or physical-

ly/fn«itally handicapped, if anyone using hot water in your home

(its into one of these ^nnips or if there is a local code or law

requiring a certain ^pwature water at the hot water tap, then

you must take spedai precautions. In addition to using the lowest

possible temperature setting that satisfies your hot water needs,

a means such as a mixing valve, should be used at the hot water

taps us^ by these people or at the vrater heater. Mixing valves

are available at plumbing supply or hardware stores. Follow man

ufacturers instructions for installation of the valves. Before

changing the factory setting on the thermostat, read the

Temperature Regulation” section in this manual.

‘AIR" IN HOT WATER FAUCETS

awarning

HYDROGEN GAS: Hydrogen gas can be produced in a hot

water system that has not been used for a long period of time

(generally two vreeks or more). Hydrogen gas is extremely

flammable and e^losive. To prevent the possibility of injury

under these conditions, we recommend the hot water hujcet

be opmed for several minutes at the kitdten sink before any

electrical appliances which are connected to the hot water sys

tem are used (such as a dishwasher or washing machine). If

hydrogen gas Is present, there will probity be an unusual

sound »milar to air escaping through the pipe as the hot water

foucet is opened. There must be no smoking or open flame

near the faucet at the time it is open.
