READ THE SAFETY
INFORMATION
Before inspecting, diagnosing, repairing or operating
any water heater, be sure to examine all of the safe-
ty and warning labels on the water heater. Follow the
instruction on these warning labels. Read and under-
stand the Use and Care Manual that was shipped with
the water heater. Failure to do so can result in unsafe
operation of the water heater resulting in property dam-
age, bodily injury, or death. If you have any problems
reading or following the instructions in the Use and
Care Manual, seek the help of a licensed and qualified
professional.
ELECTRICAL SHOCK
Troubleshooting and repairing this water heater can
expose you to electrical shock. Some of the diagnos-
tic procedures require the presence of AC and DC volt
electricity. Use extreme caution when performing these
procedures. When replacing a serviceable component,
turn off all power to the water heater and check for the
presence of power with a multi meter or test lamp.
The ignition cable carries more than 10,000 volts of
electrical energy. Use extreme caution when diagnos-
ing the Tankless Gas Water Heater.

FLAMMABLE LIQUIDS AND
VAPORS
Gasoline, as well as other flammable material and liquids
(adhesives, solvents, etc.), and their vapors are extremely
dangerous. DO NOT handle, use or store gasoline or other
flammable or combustible materials anywhere near or in
the vicinity of a water heater. The spark ignition and burn-
er assembly in the water heater controls can ignite these
vapors. Failure to do so can result in property damage,
bodily injury or death.
WATER TEMPERATURE

ered when selecting the water temperature setting on the
thermostat. Water temperatures above 125 F can cause
