TROUBLE SHOOTING HELP
THERMOSTAT AND GAS SUPPLY CHECK
A hydrogen sulfide (rotten egg) odor may result if water contains
high sulfate and/or minerals. Chlorinating the water supply
should minimize the problem, see EXTENDED NON-USE
PERIODS.
NOTE: Anode rod must remain installed (except for inspection)
to avoid shortening tank life. See LIMITED WARRANTY. Replace
as necessary.
