INSTRUCTIONS FOR USE
REFLECTIVE BARRIER WATER HEATER
Fully Encapsulated Fiberglass, Double Sided
with Aluminum Foil
WARNING FOR GAS HEATERS
WARNING FOR ELECTRIC HEATERS
Make sure the blanket does not block proper venting across the top of the heater and does not obstruct the air flow
into the burner area.
Take care that the insulation does not cover heating element controls or the power connection. Failure to do so can
cause an electric shock.
1. Completely clean the top of the heater with detergent and warm water. Do not use
solvent-based cleaners. Make sure that the water heater top is completely dry.
2. With the vinyl side out, wrap the 48" width of the insulation around the water heater with the
tabs at the top. Mark the vinyl at the point the insulation overlaps.
3. Using a knife and a straight edge, cut the jacket with the vinyl side up along the line marked
at the overlap. Cut 3 strips of tape 6" long and tape the insulation together at the top, middle
and bottom.
4. Cut out insulation over burner control area on gas units and thermostat on electric unit.
Center and apply tape down the entire length of the seam.
5. For gas heaters: Do not insulate the top of gas water heaters.
For oil heaters: Cut the remaining tape into pieces of approx. 6". Then tape the excess
insulation to the top of the water heater.
For electric heaters: Cut the excess insulation to fit around hot and cold water pipes and the
relief valve. Then use the remaining tape to fasten insulation to the top of the water heater.
Precautions: Avoid contact with skin or eyes. Wear long-sleeved, loose-fitting clothing, gloves
and eye protection. Wash with soap and water after handling.
**“R” means resistance to heat flow. The higher the R value, the greater the insulating power.
