SECTION III – START UP AND OPERATION
WARNING / CAUTION
Temperatures above 130ºF (54º C) can cause scalding. Scalding temperatures are especially
hazardous to young children, aged or handicapped persons. A serious or disabling injury can occur.
Note that a mix ing valve installed at the hot water outlet can reduce the risk of scalding at such
points of use as lavatories, sinks and bathing facilities
Excessively hot water may suggest that the upper operating thermostat has failed. If you determine
an operating control thermostat has failed, it should be replaced IMMEDIATELY by a qualified
service technician.
If the burner turns on and off every 3 to 4 minutes on a regular basis, the lower control thermostat
setting may have to be decreased. Such a "short cycling" condition accelerates wear of burner
components which can lead to early failure.
