Proper care is your responsibility. Carefully read
and understand the Operating Information in this
guide before operating the Noritz Water Heater.
Be fully aware of where the gas shut-off valve is
located and how to operate it.
Close the gas shut-off valve immediately if the
appliance is subjected to fire, overheating, flood,
physical damage, or any other damaging condition
that might affect the operation of the unit.
The Water Heater must be checked by a qualified
technician before resuming operation.
DO NOT use this Water Heater if any part has
been under water, call a qualified technician
immediately for inspecting the Water Heater and
for replacing any part of the control system and
any gas control which has been under water.
Do not power up the unit unless the gas and water
supply valves are fully opened. Make sure that fresh
air intake flue and exhaust gas flue are opened and
functional.

Contact a qualified technician if the Water Heater
needs repair or maintenance.
Ask your gas supplier for a list of qualified service
providers.

Do not operate the water heater if its combustion air intake is located in or near one of the areas or in the vicinity of products listed in
Table. These areas will always contain hazardous contaminates that can form strong acids while passing through the burner and vent
system. These acids will corrode the water heater’s heat exchanger, burner components and vent system, resulting in flue gas spillage
and/or water leakage, possible substantial property damage, severe personal injury, or death. If the water heater combustion air intake
is located in any area likely to cause or contain contamination, or if products which would contaminate the air cannot be removed, the
intake must be re-piped and terminated to another location.
