Ill. Water Heater Overall Construction
A. Glass-lined Tank
The steel, glass-lined tanks provide long life under varying water conditions. This same construction
is what is used for more than 7 million residential water heaters sold annually. The baked-on enamel
process reaches temperatures in excess of 1600°F. Three (3) year tank warranty, replaceable anode
rod, high output, fast recovery, gas connection supplied, foam jacket on all gaslelectric models.
B. Anode Protection
-
Water Heater
Each Suburban water heater is equipped with a replaceable anode rod. The sacrificial anode
equalizes aggressive water action providing cathodic protection for the tank. The anode rod is a very
important factor in tank life and should only be removed for inspection of draining. Replacement of
the anode rod is recommended when consumption or weight loss is greater than 75%. With regular
inspection and replacement of the anode (part number 231419), tank life can be greatly extended.
Frequency of anode replacement will vary depending on the water conditions and usage.
C. Temperature and Pressure Valve
Temperature and pressure relief valves will normally drip during heating cycles. In a closed system,
a liquid will expand when heated and cause a rise in temperature and pressure. How much is
excessive and why only sometimes? Here are six basic reasons:
1. The temperature and pressure of incoming water.
2. The cleanliness of the thermostat or "probe" position of valve.
3.
The pressure setting of relief valve (150 PSI).
4. Age and condition of the spring assembly inside valve.
5. The temperature setting of preset or manual thermostat.
6. The evaluation and atmospheric pressure at which the heater is used.
D. WinterizationIFlushing Instructions
.
. .
If the RV is to be stored during winter months, the water heater must be drained to prevent damage
from freezing. The followina steps can be followed to do this:
1. Turn off power and gas.
2. Turn off pressure pump or your water hook-up source.
3. Open both hot and cold water faucets.
4. Open drain on water heater.
5. Follow RV manufacturer's instructions for draining entire water system.
E. Odor from Hot Water System
Odor from the hot water system is not a service problem, and many water supplies contain sufficient
amounts of sulphur to produce an odor. The odor is similar to rotten eggs and is often referred to as
sulphur water. It is not harmful
-
only unpleasant to smell. Sulphur water can be caused by a
chemical action or by bacteria. The solution to eliminate is heavy chlorination of the water system.
Add about six ounces of heavy chlorine (common household liquid bleach) to each ten gallons in the
water tank. Then run the heavy chlorinated water through~ut the system, opening each faucet one
at a time until you smell the chlorine. Let the RV sit for a few days and the chlorine should take care
of the problem. Then you'll need to take care of the chlorine. You may consider adding a filtering
system that removes chlorine and prevents sulphur water.
