MAINTENANCE AND SERVICE

• Clean the cold-water inlet filter. (Refer to the Unit Draining and Filter Cleaning Section on this page.)

• Be sure that all openings for combustion and ventilation air are not blocked.

• The venting system should be checked annually for any leaks, corrosion, blockages or damage.

• The burner should be checked annually for dust, lint, grease or dirt.

• Keep the area around the water heater clear. Remove any combustible materials, gasoline or any

flammable vapors and liquids.

• In accordance with all local codes and common safety practices, water discharged from the pressure

relief valve can cause severe burns instantly from scalding. DO NOT touch the pressure relief valve.

• If the relief valve discharges periodically, it may be due to thermal expansion in a closed water supply

system. Contact the water supplier or local plumbing inspector on how to correct this situation.

• Visual check of burner flames (see below) through the burner window in the burner assembly located

at the middle of the water heater.

The manufacturer recommends having the water heater checked once a year or as necessary by a licensed

technician. If repairs are needed, any repairs should be done by a licensed technician.
