INSULATION BLANKETS
Insulationblanketsareavailabletothegeneralpublicforexternaluse
ongaswaterheatersbutarenotnecessarywiththeseproducts.The
purpose of an insulation blanket is to reduce the standby heat loss
encountered with storage tank heaters. Your water heater meets or
exceedstheEnergyPolicyActstandardswithrespecttoinsulationand
standbylossrequirements,makinganinsulationblanketunnecessary.
Shouldyouchoosetoapplyaninsulationblankettothisheater,you
should follow these instructions(For identication of components
mentionedbelow,seeFigure1).Failuretofollowtheseinstructions
canrestrictthe air ow required for proper combustion, potentially
resultinginre,asphyxiation,seriouspersonalinjuryordeath.
• Do notapplyinsulationtothetopofthewaterheater,asthiswill
interferewithsafeoperationoftheblowerassembly.
• Do notcovertheouterdoor,thermostatortemperature&pressure
relief valve.
• Do notallowinsulationto comewithin2”(5.1 cm)oftheoor to
preventblockageofcombustionairowtotheburner.
• Do notcover the instruction manual. Keep it onthe sideof the
water heater or nearby for future reference.
• Doobtainnewwarningandinstructionlabelsfromthemanufacturer
forplacementontheblanketdirectlyovertheexistinglabels.
• Do inspect the insulation blanket frequently to make certain it

COMBUSTION AIR AND VENTILATION
Agaswaterheatercannotoperateproperlywithoutthecorrectamount
ofairforcombustion.Donotinstallinaconnedareasuchasacloset,
unless you provide air as shown in the “Facts to ConsiderAbout
Location”section.Neverobstructtheowofventilationair.Ifyouhave
anydoubtsorquestionsatall,callyourgassupplier.Failuretoprovide
theproperamountofcombustionaircanresultinareorexplosion
