SETTING THE WATER HEATER TEMPERATURE AT 120°F (49°C)
(APPROX. "
" MARK ON FACE OF THE TEMPERATURE ADJUSTING
DIAL) WILL REDUCE THE RISK OF SCALDS. Some States or Provinces
require settings at specic lower temperatures.
Figure 6 shows the approximate water temperatures produced at various
thermostat settings. Short repeated heating cycles caused by small hot
water uses can cause temperatures at the point of use to exceed the
thermostat setting by up to 20°F (11°C). If you experience this type of
use you should consider using lower temperature settings to reduce
scald hazards.
Valves for reducing point of use temperature by mixing cold and hot
water are available. Also available are inexpensive devices that attach
to faucets to limit hot water temperatures. Contact a licensed plumber
or the local plumbing authority.
To avoid any unintentional changes in water temperature settings, the
control has a tamper resistant feature for changing the temperature
setting. To change the temperature setting follow these instructions:
1. "Wake Up" the temperature indicators by holding down both the
"COOLER" and "HOTTER" temperature adjustment buttons at
the same time for one second (see Figure 6). One or two of the
temperature indicators will light up. These indicators will only remain
on for 30 seconds if no further buttons are pressed. After 30 seconds
the control will go back to "Sleep" mode.
2. Release both of the temperature adjustment buttons.
A. To decrease the temperature press and release the "COOLER"
button until desired setting is reached.
B. To increase the temperature press and release the "HOTTER"
button until the desired setting is reached.
NOTE: Holding down the button will not continue to lower or raise the
temperature setting. The button must be pressed and released for each
temperature change desired.
SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL TO
SHUT OFF, TURN OFF THE MAIN MANUAL GAS SHUTOFF VALVE
TO THE APPLIANCE. SEE FIGURE 1 (G).
CHECKING VENTING
The following steps shall be followed with each appliance connected
to the venting system placed in operation, while any other appliances
connected to the venting system are not in operation.
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal pitch, as
required in the National Fuel Gas Code, ANSI Z223.1/NFPA 54
or the CAN/CSA-B149.1 Installation codes and these instructions.
Determine that there is no blockage or restriction, leakage, corrosion
and other deciencies which could cause an unsafe condition.
3. So far as is practical, close all building doors and windows and all
doors between the space in which the water heater(s) connected
to the venting system are located and other spaces of the building.
Turn on all appliances not connected to the venting system. Turn
on all exhaust fans, such as range hoods and bathroom exhausts,
so they shall operate at maximum speed. Close replace dampers.
4. Follow the lighting instruction. Place the water heater being
inspected in operation. Adjust thermostat so appliance shall operate
continuously.
5. Test for vent system leakage after 5 minutes of main burner operation.
TEMPERATURE REGULATION
DANGER
THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE
THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT WATER
TEMPERATURES REQUIRED FOR AUTOMATIC DISHWASHING AND
LAUNDRY USE CAN CAUSE PAINFUL SCALDING WITH POSSIBLE
SERIOUS AND PERMANENT INJURY. THE TEMPERATURE AT WHICH
INJURY OCCURS VARIES WITH THE PERSON’S AGE AND THE TIME
OF THE EXPOSURE. THE SLOWER RESPONSE TIME OF CHILDREN,
AGED OR 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.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA WHERE
THE GENERAL PUBLIC DOES NOT HAVE ACCESS. IF A SUITABLE
AREA IS NOT AVAILABLE, A COVER SHOULD BE INSTALLED OVER
THE THERMOSTAT TO PREVENT TAMPERING.Suitable covers
are available from the manufacturer, authorized service agencies or
distributors. When ordering parts be sure to have the complete water
heater Model Number, Serial Number and Series Number available. This
information can be found on the rating label afxed to the water heater.
It is recommended that lower water temperatures be used to avoid the
risk of scalding. It is further recommended, in all cases, that the water
temperature setting be set for the lowest temperature that satises
your hot water needs. This will also provide the most energy efcient
operation of the water heater. The water temperature adjustment was
factory set at the lowest temperature. Pressing the "COOLER"
button decreases temperature and pressing the "HOTTER"
button
increases the temperature.
