USERS OF THIS APPLIANCE SHOULD BE AWARE THAT GAS
COMPONENTS WEAR OUT OVER A PERIOD OF TIME. THE
GAS CARRYING COMPONENTS OF THIS APPLIANCE SHOULD
BE INSPECTED FOR PROPER OPERATION PERIODICALLY
BY A QUALIFIED SERVICE TECHNICIAN.
MAIN BURNER
Check main burner every 12 months for proper ame characteristics.
This is done by removing door(s) on heater, g. 1. The main burner
should provide complete combustion of gas; ignite rapidly; give
reasonably quiet operation; cause no excessive ame lifting from
burner ports. Make sure that the ow of combustion and ventilation
air is not blocked.
WARNING
Use appropriate caution when performing this inspection and
do not put any part of your body immediately in front of the
combustion chamber.
If proper flame characteristics are not evident, check for
accumulation of lint or other foreign material that restricts or
blocks the air openings in the heater or burner. Also check AIR
REQUIREMENTS.
WARNING
SOOT BUILD-UP INDICATES A PROBLEM THAT REQUIRES
CORRECTION BEFORE FURTHER USE. Consult with a qualied
service technician.
Should the main burner or burner air openings require cleaning,
turn the control switch to “OFF” position and allow the burner to
cool. Remove the burner and clean with a soft brush. Clean main
burner orice with a suitable soft material.
HIGH TEMPERATURE LIMIT SWITCH
The thermostat has a single use built-in limit switch which will shut
off gas to burner in case of excessive water temperatures. The
thermostat must be replaced if the limit switch opens.
VENTING SYSTEM
HAVE VENTING SYSTEM CHECKED EVERY SIX MONTHS FOR
OBSTRUCTIONS AND/OR DETERIORATION IN VENT PIPING.
A. Insofar as is practical, close all doors, windows and air inlets to
the building. Turn on all exhaust fans (range hood, bathroom
exhaust, etc.) so they will operate at their maximum speed.
Close replace dampers.
B. Turn water temperature adjusting knob to full, counterclockwise
and open water faucet if necessary to keep burner in
operation.
C. “CHECKING THE DRAFT.” Operate the water heater for
several minutes and check to see if it is venting properly by
passing a lit match or paper near the opening of the Air Mixing
Box (See gure 11). If the draft is proper, the match ame
will be drawn into the Air Mixing Box. If not, the combustion
products will tend to extinguish the ame. If an improper draft
exists, do not operate the water heater until proper adjustments
or repairs are made to provide adequate draft through the gas
vent.
D. Next, turn on all other fuel burning appliances within the same
room so they will operate at their full input.
Repeat step C above.
POWER VENTER MAINTENANCE
The water heater must be inspected quarterly. Points of
inspection are:
1. MOTOR - Motor must rotate freely. This is a sealed motor
and no oiling is required.
2. WHEEL - Wheel must be clean of soot, ash or any other
coating which inhibits either rotation or air ow. Remove all
foreign material from vent system before operating.
3. AIR SUPPLY BOX - Every month check operation and make
sure nothing is blocking dilution air entrance.
4. The pressure switch part inside the power venter must be
open and free from deposits of soot, carbon, etc.
For safety and satisfactory operation it is recommended that the
heater be checked once a year by a competent service person.
FIGURE 11
T & P VALVE
At least once a year, the temperature and pressure relief valve
must be checked to ensure that it is in operating condition. Lift
the lever at the top of the valve several times until the valve seats
properly and operates freely.
WARNING
THE WATER PASSING OUT OF THE VALVE DURING THIS
CHECKING OPERATION MAY BE EXTREMELY HOT. AVOID
CONTACT AND DISCHARGE SAFELY TO PREVENT WATER
DAMAGE.
DRAINING
Periodically open the drain valve and allow the water to run until
it ows clean. This will help prevent sediment build-up in the
tank.
It is normal for lime and scale deposits to form within the tank
and on the heat exchanger surfaces. Such deposits will not
be removed by periodic draining. It is necessary to chemically
delime the affected parts in water areas where such deposits
are encountered. Deliming information can be obtained from the
water heater manufacturer at, 500 Tennessee Waltz Parkway,
Ashland City, TN 37015.
