START-UP PROCEDURES
WARNING!
This water heater is equipped with an
adjustable thermostat to control water
temperature. Hot water temperatures
required for automatic dishwasher and
laundry use could cause scald burns
resulting in serious personal injury and/or
death. The temperature at which injury
occurs varies with the person’s age and
time of exposure. The slower response
time of disabled persons increases the
hazards to them. Never allow small
children to use a hot water tap or to draw
their own bath water. Never leave a child
or disabled person unattended in a
bathtub or shower. Since the thermostat
temperature setting could be set too high,
adjust the thermostat temperature setting
to 125°F or lower. Lower settings help
reduce risk of scald injury. Remember, no
water heater system will provide exact
temperature at all times. Allow a few days
of operation at this setting to determine
the correct temperature setting consistent
with your needs and remember, “Hotter
water increases the risk of scald injury.”
Also, the water heater should be located
in an area where the general public does
not have access to set temperatures.
WARNING!
Failure to follow these instructions can
result in serious person injury or death.
Do not relight pilot or start burner with
combustion chamber full of gas or oil
vapor, or with very hot combustion
chamber.
1. Study the burner start-up information included
in this manual carefully.
2. Fill the water heater tank with water. Open the
relief valve or a nearby hot water faucet to
allow air in the tank to escape.
Be sure all connections into the tank are tight
as leaks at tank fittings will damage the
insulation.
3. The top thermostat is a temperature limiting
safety device set at 200°F. The thermostats
are set at the factory at 130°F on the upper
operating thermostat and 120°F on the lower
operating thermostat. The lower operating
thermostat should be set 10° lower than the
upper operating thermostat setting. Adjustment
may be made by turning the thermostat dial to
the desired temperature.
