GENERAL SAFETY INFORMATION

PRECAUTIONS

DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN UNDER
WATER. Immediately call a qualied service technician to inspect
the appliance 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 qualied service agency.

1. External re.

2. Damage.

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.

When servicing this unit, verify the power to the unit is turned off prior to opening the control cabinet door.

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 ammable.
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 ow.
OR OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN.

THERE SHOULD BE NO SMOKING

markings into useful information. Both of these references should
be used to identify the heater, its components and optional
equipment.

2. The installation must conform with these instructions and the
local code authority having jurisdiction and the requirements
of the power company. In the absence of local codes, the
installation must comply with the latest editions of the National
Electrical Code, NFPA 70 or the Canadian Electrical Code CSA
C22.1. The National Electrical Code may be ordered from:
