PRECAUTIONS
DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN
EXPOSED TO FLOODING OR WATER DAMAGE. Immediately
call a qualified service technician to inspect the water heater and to
replace any part of the control system which has been under water.
If the unit is exposed to the following, do not operate heater until all
corrective steps have been made by a qualified service technician.
1.
External fire.
2.

3.
Firing without water.
GROUNDING INSTRUCTIONS
This water heater must be grounded in accordance with the National
Electrical Code and/or local codes. These must be followed in all
cases. Failure to ground this water heater properly may also cause
erratic control system operation on ELECTRONIC CONTROL
models.
This water heater must be connected to a grounded metal,
permanent wiring system; or an equipment grounding conductor must
be run with the circuit conductors and connected to the equipment
grounding terminal or lead on the water heater.
LIMITING THE RISK OF SCALDING
For a variety of reasons, water heaters can produce water that is
much hotter than its temperature setting. Take precautions to prevent
this higher temperature water from reaching the water fixtures.
When servicing this unit, verify the power to the unit is turned off prior to opening the control cabinet door.
HAZARD MESSAGES
Read and understand this instruction
manual and the safety messages
herein before installing, operating or
servicing this water heater.
Failure to follow these instructions and
safety messages could result in death
or serious injury.
This manual must remain with the
water heater.
GENERAL SAFETY INFORMATION
GENERAL SAFETY INFORMATION
To reduce the risk of unusually hot
water reaching the fixtures in the
house, install thermostatic mixing
valves at each point of use.
A properly adjusted thermostatic mixing valve at each point of use
allows you to set the tank temperature to a higher setting without
increasing risk of scalds. A higher temperature setting allows the
tank to provide much more hot water and can help provide proper
water temperatures for appliances such as dishwashers and washing
machines.
HYDROGEN GAS (FLAMMABLE)
Hydrogen gas can be produced in a hot water system served by this
heater that has not been used for a long period of time (generally two
weeks or more). Hydrogen gas is extremely flammable. To reduce
the risk of injury under these conditions, it is recommended that the
hot water faucet be opened for several minutes at the kitchen sink
before using any electrical appliance connected to the hot water
system. If hydrogen is present there will probably be an unusual
sound such as air escaping through the pipe as the water begins
to flow. THERE SHOULD BE NO SMOKING OR OPEN FLAME NEAR
THE FAUCET AT THE TIME IT IS OPEN.
Electrical Shock Hazard
If the water heater becomes immersed
in water up to or above the level of the
bottom of the element doors, the
heater should be examined by a
qualified service agency before it is
placed in operation.

Burn Hazard
Explosion Hazard
Flammable hydrogen gases
may be present.
Keep all ignition sources away
from faucet when turning on
