Important Information
READ CAREFULLY
The following terms are used throughout this manual to bring attention to the
presence of hazards at various risk levels, or to important information concerning
product life.
DANGER
CAUTION
Indicates an imminently hazardous
situation, which, if not avoided, will result
in death, serious injury or substantial
property damage.
Indicates potentially hazardous situation,
which, if not avoided, may result in
moderate or minor injury or property
damage.
NOTICE
WARNING
Indicates special instructions on
installation, operation or maintenance,
which are important but not related to
personal injury hazards.
Indicates a potentially hazardous
situation, which, if not avoided, could
result in death, serious injury or
substantial property damage.
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a
temperature setting of 140°F (60°C). To protect against hot water injury, install an ASSE
approved mixing valve in the water system. This valve will reduce point of discharge
temperature by mixing cold and hot water in branch water lines. A licensed plumbing
professional or local plumbing authority should be consulted.
NOTICE
The water heater is equipped with an energy cut out device to prevent overheating. Should
overheating occur or the gas supply fails to shut off, turn off the manual gas control valve to the
water heater and call a qualified service technician.
Whenever the water heater is filled with cold water, condensate will form on the cool tank
surface and drops of water will fall on the hot burner and combustion chamber surfaces
producing a “sizzling” noise. Condensation is normal and does not indicate a leak. It will
disappear when the tank becomes heated.
CAUTION
The water heater, when set at a lower temperature setting, is not capable of producing hot water
of sufficient temperature for sanitizing purposes.

Important Information
NOTICE
The lower the temperature setting, the greater the energy efficiency, both to heat the water and
to maintain the storage temperature during standby periods. Lower water temperatures also
extend tank life. Remember, no water heating system will provide exact temperatures at all
times. Allow a few days of operation at this setting to determine the correct temperature setting
consistent with the requirements for the installation.
WARNING
Do not operate the water heater or Accessory Module without the Accessory Module cover in
place. Do not operate the water heater or Setback Control without the Setback Control Junction
Box Assembly cover in place.
Do not operate water heater, Accessory Module, and Setback Control with jumpered or absent
controls or safety devices.
Turn off or disconnect the electrical power supply to the water heater and its accessories before
servicing. Label all wires prior to disconnection when servicing controls. Wiring errors can
cause improper and dangerous operation. Verify proper operation after servicing.
All electrical wiring must be installed and grounded in accordance with local codes, or in the
absence of local codes, the National Electrical Code, ANSI/NFPA 70 and/or CSA C22 Electrical
Code.
Do not use wire holders to the right of the water heater gas valve. The screws used for the wire
holders can damage the water heater internal components.
For energy efficient operation of your water heater, the suggested initial water temperature setting is
120˚F (49˚C). During the winter season, or any cold period, you may desire a higher water temperature
setting to adjust for the colder incoming water. This adjustment, however, may cause additional
condensation to form on the cooler tank surface. This does not mean the tank is leaking. During summer
months, the warmer incoming water temperatures will benefit the performance of your water heater and
reduce the amount of condensation developed.
Condensation does not mean your tank is leaking. Over 40% of reported tank leaks on installation are
proven to be condensation. To avoid unnecessary expense and inconvenience, make sure the tank is
leaking before calling a service technician.
Water temperature over 125°F
can cause severe burns
instantly or death from scalds.
Children, disabled and elderly
are at highest risk of being
scalded.
Review this instruction manual
before setting temperature
at water heater.
Feel water before bathing or
showering.
Temperature limiting valves
are available.

WARNING
The Leak Sensor can be mounted in a water heater drain pan. If the installation does not use a
drain pan, the dam should be used to corral the water heater tank leak to the Leak Sensor.
The bottom of the Leak Sensor must be touching the floor. Failure to do so will result in
inaccurate leak detection.

Inlet Shut-off Valve Installation
In the following section, the instructions detail how to install the Inlet Shut-off Valve. If installed,
this device will shut off the water supply to the water heater after the Leak Sensor has sensed
and verified a water heater tank leak has occurred. The Accessory Module and Leak Sensor
must be installed for the Inlet Shut-off Valve to work with the water heater gas control.
The inlet shut-off valve can take up to 16 minutes to close, if installed, after a water heater tank
leak is sensed and verified.
Unpack the Inlet Shut-off Valve
Step 1: Remove the Inlet Shut-off Valve and its components from their packaging, as shown in Figure 70.
Figure 70
Prepare the Water Heater for the Installation of the Inlet Shut-off Valve
Step 2: If the water heater is already installed and the water heater is full of water, pressure must be
removed from the water heater tank, and the tank must be at least partially drained.
WARNING
If installed properly, the Inlet Shut-off Valve will prevent continuous flow when a water heater
tank leak is detected and verified. If damage will occur, a drain pan must be installed and piped
to an adequate floor drain.
