INSULATIONBLANKETS

encounteredwithstorage tankheaters. Your Kenmorewater heater
meets or exceeds the NationalAppliance Energy ConservationAct
standards with respect to insulation and standby loss requirements,
makinganinsulationblanketunnecessary.
Should you choose to apply an insulation blanket to this heater, you
should follow these instructions (For identification of components
mentioned below, see Figure 1). Failure to follow these instructions
can restrict the air flow required for proper combustion, potentially
resultingin fire,asphyxiation, seriouspersonalinjuryordeath.
•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, thermostator temperature & pressure
reliefvalve.
•Do not allow insulation to come within 2" (5.1 cm) of the floor to
preventblockageof combustionair flowto theburner.
•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 Sears
forplacement onthe blanketdirectly overthe existinglabels.
•Do inspect the insulation blanket frequently to make certain it
doesnotsag, therebyobstructing combustionair flow.
