10. WATER TEMPERATURE ADJUSTMENT

approximately 120°F.

CAUTION: Hotter water increases the risk
of scald injury. Consult the instruction
manual before changing temperature.

explosion may result causing property damage, personal injury or loss
of life.

with an ignition device which automatically lights the
burner.  Do NOT try to light the burner by hand.

B. BEFORE OPERATING smell all around the

appliance area for gas. Be sure to smell next to the
floor because some gas is heavier than air and will
settle on the floor.

WHAT TO DO IF YOU SMELL GAS:

Do not try to light any appliance.

Do not touch any electric switch;
do not use any phone in your building.

Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire
department.

C. Use only your hand to push in the gas control

buttons. Never use tools. If the control buttons will
not push in, don’t try to repair them, call a qualified
service technician. Force or attempted repair may
result in a fire or explosion.

D. Do not use this appliance if any part has been

under water. Immediately contact a qualified
installer or service agency to replace a flooded
water heater. Do not attempt to repair the unit. It
must be replaced!
