UNIT DRAINING and FILTER CLEANING
MAINTENANCE AND SERVICE
• Clean the cold-water inlet filter. (Refer to "Unit Draining and Filter Cleaning" 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,
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.
Turn off the electrical power supply and close the manual gas shutoff valve
and the manual water control valve before servicing.
WARNING
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 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.
