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 minimum efficiency requirements 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 identification of components mentioned below, see Figure 1). Failure to follow these instructions can restrict the air flow required for proper combustion, potentially resulting in fire, 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 draft hood.

•Do not cover the outer door, thermostat or temperature & pressure relief valve.

•Do not allow insulation to come within 2” (50.8 mm) of the floor to prevent blockage of combustion air flow 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 does not sag, thereby obstructing combustion air flow.
