TEMPERATURE REGULATION
DANGER
THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE
THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT WATER
TEMPERATURES REQUIRED FOR AUTOMATIC DISHWASHER
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 through Apcom Inc., 125 Southwest Parkway, Franklin,
TN 37065 or contact them by phone, 615-794-5574 or fax
615-791-0660.

FIGURE 7.
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 dial be set for the lowest temperature which
satisfies your hot water needs. This will also provide the most
energy efficient operation of the water heater. The water
temperature adjusting dial was factory set at the lowest
temperature; all the way clockwise to the mechanical stop. Turning
the dial counterclockwise
increases temperature and clockwise
reduces temperature.
SETTING THE WATER HEATER TEMPERATURE AT 120°F (49°c)
(APPROX. " " MARK ON FACE OF THERMOSTAT) WILL REDUCE
THE RISK OF SCALDS. Some states require settings at specific
lower temperatures.
Figure 7 shows the approximate water temperatures produced at
various thermostat dial 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.
CHECK 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 and
in these instructions. Determine that there is no blockage or
restriction, leakage, corrosion and other deficiencies 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 fireplace dampers.
4. Follow the lighting instruction. Place the water heater being
inspected in operation. Adjust thermostat so appliance shall
operate continuously.
5. Test for draft hood spillage at the relief opening after 5 minutes
of main burner operation.
6. After it has been determined that each appliance connected to
the venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, fireplace dampers
and any other gas burning appliance to their previous conditions
of use.
7. If improper venting is observed during any of the above tests,
the venting system must be corrected.
WARNING
FAILURE TO CORRECT BACK DRAFTS MAY CAUSE AIR
CONTAMINATION AND UNSAFE CONDITIONS.
