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).
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.
I
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. 5-3) is designed to open if the temperature of the
water within the heater reaches 210F, 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.
I
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 exceedst the relieving point of the P & T
Valve, the valve will relieve the excess pressure.
Suburban recommends that a check valve not be installed directly at the inlet to the water heater
tank. This will increase weeping of the pressure relief valve.
