Operational Conditions
SMELLY WATER
rn cach _atcr hcatcr thcrc is ins_licd at Icast onc anodc rod (scc
parts scction) for corrosion protcction of tilc tank, Ccreain watcr
conditions wili causc a rcaction bctwccn this rod and tilc _atcr.
Thc most common complaint associatcd with tilc anodc rod is
onc of a "rottcn cgg smcll'. This odor is dcrivcd from hv&'ogcn
sulfldc gas dissolvcd in tilc watcr, Tbc smcll is tilc rcsult of_ur
Fkctors _-Mch mt_t all bc prcscnt for thc odor to dcvclop:
a, a conccnrwation of stdfiktcin thc supply _atcr,
b, little or no dissolved oxygen in the water.
c, a sulfate rcducing bactcria within the watcr hcatcr.
(This harmless bactcrh is non-toxic to humans.)
d, an cxccss of activc hydrogen in thc tank. Tbis is causcd
by the corrosion protcctivc action ofthc anode.
Smclly _atcr may bc climinatcd or rcduccd in somc watcr hcatcr
modcls by rcplacing thc anodc(s) _4th onc oflcss activc matcrial,
and thcn chlorinating thc watcr hcatcr rank and all hot _atcr
lines. Con_ct thc local Scaa's Scr_4cc Center for furthcr informa+
tion conccming an Anodc Rcplaccmcnt K t//900 453 and this
Chlorination Trcatmcnt,
lf thc smclly watcr pcrsists aftcr thc anode rcplaccmcnt and dllo-
rination trcatmcnt, wc can only suggcst that continuous chlori-
nat{on and filtcring conditioning cquipmcnt bc considcrcd to
diminatc thc watcr problcm.
Do not rereov¢ the anode leaving the tank _nprotectexL By
doing so, all warranty on the water heater tank is voided.
RUMBLING NOISE
ln somc watcr arcas, scalc or mincral dcposits will build up on
your hcating dcmcnts. This buildup will causc a rumbling noisc,
Follow Elcmcnt ClcaningiRcplaccmcnt instructions to clcan
and rcplacc thc clcmcnts.
HIGH TEMPERATURE SHUT
OFF
SYSTEM
Thc watcr hcatcr has a high limit shut off systcm with a rcsct
button Iocatcd on thc thcrmostat.
Follow thc rcsctting instructions which rcfcr to thc high limit
bchind thc acccss pancl.
NOTE, Ifyoor water heater is €onnected to an "OFF PEAK"
dock, and uses the "3 wire lead" wiring diagram in the
"Wiring Diagram" section, than the water heater will have a
hi-limit on both the _pper and lower thermostats÷ Follow
the insm*ctlons to reset the hi-limit behind the upper and
lower access panels÷
* Bcforc bcginning, turn "OFF" clcctrical powcr supply to thc
watcr hcatcr.
"AIR"
IN HOT WATER FAUCET'S
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long peri-
od of tlme (generally two weeks or more). Hydrogen gas
is extremely flammable and explosive. To prevent the
possibil;ty of injury under these cond;tions, we recom-
mend the hot water faucet be opened for several min-
utes at the kitchen s;nk before any electrical appl;ances
wh;ch are connected to the hot water system are used
(such as a dishwasher or wash;ng machine). If hydrogen
gas ls present, there will probably be an unusual sound
skn;lar to alr escapingthrough the pipe as the hot water
faucet is opened. There must be no smoking or open
flame near the faucet at the time ;t ls open.
AWARNING
HAZARD OF ELECTRICAL SHOCKI Before removing
any access panels or sarvlclng the water heater, make
sure the electrlcal supply to the water heater ;s turned
"OFF", Failure to do th;s could result in DEATH, SERI-
OUS BODILY INJURY,OR PROPERTY DAMAGE,
