OPERATING INSTRUCTIONS
WARNING
Water heaters are heat-producing appliances. To avoid damage or injury
there must be no materials stored against the water heater, and proper
care must be taken to avoid unnecessary contact (especially by children)
with the water heater. UNDER NO CIRCUMSTANCES SHALL
FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT
THINNER BE USED OR STORED IN THE VICINITY OF THE WATER
HEATER OR IN ANY LOCATION FROM WHICH FUMES COULD
REACH THE WATER HEATER.
Installation or service of this water heater requires ability equivalent to
that of a licensed tradesman in the field involved. Plumbing and
electrical work are required.

setting.

to interrupt space heating.
2. Thermostat satisfied.

circulator and de-energizing relay.
b. Normally open contacts open, stopping boiler operation.

WARNING
SCALDING
This water heater can deliver scalding temperature water at any
faucet in the system. Be careful whenever using hot water to avoid
scalding injury. By setting the thermostat on this water heater to
obtain an increased water temperature, you may create the potential
for scald injury. To protect against injury, you should install an ASSE
approved mixing valve (a device to limit the temperature of water to
protect against scald injury via mixing hot and cold water supply) in
the water system. This valve will reduce point of discharge
temperature in branch supply lines. Such valves are available from
the manufacturer of this water heater or a local plumbing supplier.
Please consult with a plumbing professional.
