START UP
See
Features and Components
(page 8) for the location of
components mentioned in the instructions that follow.
NEVER turn on power to the water heater without being certain the
water heater is filled with water and a temperature and pressure
relief valve is installed in the relief valve opening.
DO NOT TEST ELECTRICAL SYSTEM BEFORE HEATER IS FILLED
WITH WATER. FOLLOW FILLING AND START-UP INSTRUCTIONS
IN OPERATION SECTION.
Full power is present whenever the
cabinet door is opened, even with
the pilot switch turned off.
Electrical Shock Hazard
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.
Burn Hazard
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.
Burn Hazard
If you choose a higher temperature
setting, install thermostatic mixing
valves at each point-of-use to help
avoid scalding.
FILLING THE WATER HEATER
Property Damage Hazard
To avoid water heater damage, fill tank with water
before operating.
CAUTION
1.
Turn off the electrical disconnect switch.
2.
Close the water heater drain valve.
3.
Open a nearby hot water faucet to permit the air in the system
to escape.
4.
Fully open the cold water inlet pipe valve allowing the heater and
piping to be filled.
5.
Close the hot water faucet as water starts to flow. The heater is
now ready for STARTUP and TEMPERATURE REGULATION.
INITIAL START UP
The following checks should be made by the installer when the heater
is placed into operation for the first time.
1.
Turn off the electrical disconnect switch.
2.
Open the front panel or top access cover, check all water and
electrical connections for tightness. Also check connections on top
and or sides of heater. Repair water leaks and tighten electrical
connections as necessary.
3.
Depress the red manual reset button on each Thermostat/ECO
combination control. See
Temperature Regulation
(page 16)
4.
Turn on the electrical disconnect switch.
5.
Observe the operation of the electrical components during the first
heating cycle. Use care as the electrical circuits are energized.
6.
Close the front panel or top access cover.
Temperature control and contactor operation should be checked by
allowing heater to come up to temperature and shut off automatically.
Use care as the electrical circuits are energized.
DRAINING THE WATER HEATER
The water heater must be drained if it is to be shut down and exposed
to freezing temperatures. Maintenance and service procedures may
also require draining the heater.
1.
Turn off the electrical disconnect switch.
2.
Open a hot water valve until the water is cool, then close the
supply water inlet valve to heater.
3.
Attach hose to outlet opening of drain valve and direct end to
drain.
4.
Open a nearby hot water faucet and the heater drain valve.
5.
If the heater is being drained for an extended shutdown, it is
suggested the drain valve be left open during this period. The
hose may be removed.
Follow the instructions in
Filling the Water Heater
(page 15) when
restoring hot water service.
• Burn hazard.
• Hot water discharge.
• Keep hands clear of drain
valve discharge.
