Turn off the electrical power supply and close the manual gas shutoff valve

and the manual water control valve before servicing.

WARNING

• Clean the cold-water inlet filter. (Refer to 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 and terminations 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 unit checked once a year or as necessary by a licensed technician. If

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

UNIT DRAINING and FILTER CLEANING

1. Close the manual gas shutoff valve.

2. Turn off power to the unit and wait a couple of seconds. Turn

on again.

3. Wait 30 seconds, and then turn off power to the unit.

4. Close the inlet water shutoff valve.

• If the heater is part of an Easy-Link or Multi-Unit System,

close the inlet and outlet shutoff valves to isolate the

heater. Then proceed to step 6.

5. Open all hot water taps in the house. When the residual

water flow has ceased, close all hot water taps.

6. Have a bucket or pan to catch the water from the unit's drain

plugs. If Isolation valves are installed, open the drains to

drain the water. If isolation valves are not installed, unscrew

the two drain plugs (large and small) to drain all the water

out of the unit. Do not lose the o-rings that will be on the

two drain plugs.

7. Wait a few minutes to ensure all water has completely

drained from the unit.

8. Clean the filter: Check the water filter located within the

cold inlet. With a tiny brush, clean the water filter of any

debris which may have accumulated and reinsert the filter

back into the cold water inlet.

9. Securely screw the drain plugs back into place.

Hand- tighten only.
