ANODE PROTECTION
The tank in this water heater is protected by a magnesium or
aluminum anode (Fig. 5-2) to prolong the life of the tank. Under
normal use, the anode rod will deteriorate and because of this,
we recommend it be replaced yearly.
NOTE: Water with high levels of iron and/or sulfate will
increase the rate of deterioration; therefore, more
frequent replacement may be required.
Operating the water heater without proper anode protection will
decrease tank life and will void your warranty on the tank.
NOTE: Tank is drained by removing anode rod (See "Drain
and Storage" instructions in the maintenance
chapter).
To extend anode life, drain water from tank whenever RV is not being used. Avoid any extended
time of non use with water in tank.
Also, refer to section on winterizing.
y
WARNING! Do not replace the anode rod with any non-Suburban accessory part,
such as "add-on" electric heating element. Items such as these are not approved to be
installed in Suburban products. They could create an unsafe condition and will also
void all warranties.
PRESSURE RELIEF VALVE
The temperature and pressure relief valve (Fig. 5-2) is designed to open if the temperature of the
water within the heater reaches 210°F, or if the water pressure in the heater reaches 150 pounds.
Recreation vehicle water systems are closed systems and during the water heating cycle the
pressure build-up in the water system will reach 150 pounds. When this pressure is reached, the
pressure relief valve will open and water will drip from the valve. This dripping will continue until
the pressure is reduced to below 150 pounds, and the valve closes. This condition is normal and
does not indicate a defective relief valve.
y
WARNING: Do not place a valve between the relief valve and the tank. Do not plug
the relief valve under any circumstances.
WATER WEEPING OR DRIPPING FROM PRESSURE RELIEF VALVE
You may experience water weeping or dripping from your water heater's Pressure and
Temperature (P & T) Relief Valve when your water heater is operating. Water weeping or
dripping from the P & T Valve does not always mean the P & T Valve is defective. As water is
heated, it expands. The water system in a recreation vehicle is a closed system and does not allow
for the expansion of heated water. When the pressure of the water system exceeds the relieving
point of the P & T Valve, the valve will relieve the excess pressure.
