Routine$Preventative$Maintenance
Properly'maintained,'your'water'heater'
will'provide'years'of'dependable'troubleE
free'service.'
It'is'recommended'that'a'periodic'
inspection'of'the'burner,'relief'valve,'
air'intake'filter,'water'filter'and'venting'
system'should'be'made'by'service'
personnel'qualified'in'gas'appliance'repair.
It'is'suggested'that'a'routine'preventive'
maintenance'program'be'established'and'
followed'by'the'user.
At'least'once'a'year,'lift'and'release'the'
lever'handle'on'the'pressure'relief'valve,'
located'in'the'hot'outlet'piping'of'the'
water'heater,'to'make'certain'the'valve'
operates'freely.'Allow'several'gallons'to'
flush'through'the'discharge'line'to'an''
open'drain.
NOTICE:$If$the$pressure$relief$valve$$
on$the$hot$water$heater$discharges$
periodically,$this$may$be$due$to$a$
problem$in$the$water$system.$Contact$
the$water$supplier$or$your$plumbing$
contractor$on$how$to$correct$this.$DO$
NOT$plug$the$relief$valve$outlet.
Rapid'closing'of'faucets'or'solenoid'
valves'in'automatic'water'using'appliances'
can'cause'a'banging'noise'heard'in'a'
water'pipe.'Strategically'located'risers'in'
the'water'pipe'system'or'water'hammer'
arresting'devices'can'be'used'to'minimize'
the'problem.
Inspect'the'area'around'the'water'heater''
to'ensure'a'safe'operating'environment.'
Keep'appliance'area'clear'and'free'from'
combustible'materials,'gasoline'and'other'
flammable'vapors'and'liquids.
Ensure'the'unit'has'not'been'damaged.''
If'damage'or'denting'is'present,'contact''
a'service'personnel'to'verify'proper'
operation.
Check'for'any'abnormal'sounds'during'
normal'operation'of'the'water'heater.
