Operating The Temperature Control
System
Water temperature adjustment
The water temperature setting can be adjusted from
32°C (91°F) to 68°C (155°F). Turn the Gas Control Valve/
Temperature Knob to the desired setting/temperature.
Note:
The temperatures indicated are approximates. The
actual temperature of the heated water may vary.
Operating modes and settings
Standard Mode - The controller adjusts the water heater to
maintain the temperature set by the user.
Low Setting - The Low setting (LOW) sets the controller at
approximately 32°C (91°F). This setting is recommended
when the water heater is not in use for a long period of
time. This effectively turns the controller temperature setting
down to a temperature that prevents the water in the water
heater from freezing while still conserving energy.
Exposure to water
IMPORTANT:
Should the water heater be subjected to flooding, fire, or
other unusual condition, turn off gas at the manual gas
shut-off valve and water at the inlet valve to the heater. Do
not put the heater in operation until it has been thoroughly
checked by a qualified gas technician.
Tampering
Tampering with the thermostat, gas valve or temperature
pressure relief valve is DANGEROUS and voids all warran-
ties. Only qualified personnel should service these compo-
nents.
Status Light Code
Normal Flashes:
0 Flashes Indicates Control Off/Pilot Out.
1 Flash
Indicates Normal Operation.
A continuous light indicates that the gas control valve/
thermostat is shutting down.
Diagnostic Flashes:
If the water heater is not working, look for the following
diagnostic flashes after lighting the pilot. For more details,
see “Status Light and Diagnostic Code Troubleshooting
Chart.”
2 Flashes Indicates Thermopile Voltage Low
4 Flashes Indicates Overheat Failure
5 Flashes Indicates Sensor Failure
7 Flashes Indicates Electronic Control Failure
8 Flashes
See “Status Light and Diagnostic Code
Troubleshooting Chart.”
V) MAINTENANCE INSTRUCTIONS
General Housekeeping
As a precaution against fire, and to maintain an adequate
flow of combustion air to the heater:
•
keep the appliance area clear and free from combustible
material, gasoline, and other flammable vapours and
liquids.
•
keep the terminal openings unobstructed.
•
do not pile cartons, paper or combustible material on top
of the heater.
Tank
Drain at least a pail of water from the drain valve once a
month. Some deposit will be washed out of the tank. If larger
particles, resembling coarse sand are washed out, or if the
drain becomes clogged while draining, an excess of lime
deposit has settled on the tank bottom and it is time to do
a major tank cleaning. Consult your local Gas Utility or a
qualified serviceman.
Venting System Inspection
Every 3 months, when inspecting the burner flame, an
inspection of the venting system should be made.
Check:
1. That the vent terminal is securely attached and free of
obstruction.
2. The air pipe to make certain its components are securely
fastened, sealed and are in good condition.
3. That the inner door on water heater is securely fas-
tened.
CORRECT ANY DEFECTS IMMEDIATELY.
Gas Control
The heater operates under a fully automatic control. Once
the desired water temperature has been selected, the gas
control will maintain that temperature within close limits.
DO NOT TAMPER WITH THE GAS CONTROL!
If the heater or the controls have been subjected to flooding,
shut off the gas at the manual shut-off valve to the heater
and call your gas company.
For gas control replacement, contact your local gas utility, or
a qualified serviceman. The replacement control must be a
manufacturer’s approved replacement for the control which
has been removed.
