READ THE SAFETY INFORMATION
Before inspecting, diagnosing, repairing or operating any
water heater, be sure to examine all of the safety and
warning labels on the water heater. Follow the instruction
on these warning labels. Read and understand the Use

ELECTRICAL SHOCK
Troubleshooting and repairing this water heater can
expose you to electrical shock. Some of the diagnostic
procedures require the presence of AC and DC volt elec-
tricity. Use extreme caution when performing these pro-
cedures. When replacing a serviceable component, turn
off all power to the water heater and check for the pres-
ence of power with a multi meter or test lamp.
The ignition cable carries more than 10,000 volts of elec-
trical energy. Use extreme caution when diagnosing the
Tankless Gas Water Heater.

flammable or combustible materials anywhere near or in the
vicinity of a water heater. The spark ignition and burner as-
sembly in the water heater controls can ignite these vapors.
Failure to do so can result in property damage, bodily injury
or death.
