THERMOSTAT AND MANUAL RESET

The model water heaters listed above are equipped with a high temperature limit 

as a cut-off device. Temperature above 82

°

C will cause manual reset button to trip 

shutting down the electric element.

To activate element, the water temperature must be below 37

°

C. Push reset 

button to

ANODE PROTECTION

The tank in this water heater is protected by a magnesium or aluminum anode to 

prolong the life of the tank. Removal of the anode will decrease tank life and will 

void the warranty on the inner tank. Anode must be checked every 6 (six) months, 

and replaced if below 50% of original diameter, failure to do so will void your 

warranty. Use only genuine Suburban anode rods. Use of other anodes may void 

the warranty. Anode performance depends on water quality, therefore are 

NOT

 

covered by warranty. 

To prevent a water leak when replacing the anode rod, a pipe thread sealant 

approved for potable water (such as Teflon Tape) must be applied to the threads 

of the anode rod.  Proper application of a thread sealant will not interfere with the 

anode’s tank protection.

Anode Dimensions:   Length - 215mm, Diameter - 17mm.

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 the section on winterizing.

WARNING! Do not replace the anode rod with any non-Suburban 

accessory part, such as an “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 is designed to open if the temperature 

of the water within the heater reaches 98.9 degrees Celsius, or if the water 

pressure in the heater reaches 850 kPa. Recreational vehicle water systems are 

closed systems and during the water heating cycle the pressure build-up in the 

water system will reach 850 kPa. 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 850 kPa. Once the pressure has dropped 

below 850 kPa, the valve will close. This condition is normal and does not indicate 

a defective relief valve.

WARNING! Do not plug, cap or reduce the outlet pressure and temperature 

valve.

The pressure-relief device is to be operated regularly to remove lime deposits and 

to verify that it is not blocked.

DANGER! Failure to operate the relief valve easing gear at least once every 

six months ma

y result in the water heater exploding.  Continuous leakage of 

water from the valve may indicate a problem with the water heater.

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 recreational 

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. 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.

One way to reduce the frequency of this occurrence is to maintain an air pocket 

at the top of the water heater tank. This air pocket will form in the tank by design. 

However, it will be reduced over time by the everyday use of your water heater.

To replenish this air pocket:

 

1.

  Turn off water heater.

 

2.

  Turn off cold water supply line.

 

3.

  Open a tap in the RV.

 

4.

  Pull out on the handle of the Pressure Relief (P & T) Valve and allow water 

to flow from the valve until it stops.

 

5.

  Release handle on P & T Valve - it should snap closed.

 6.

  Close tap and turn on cold water supply; as the tank fills, the air pocket will 

develop.

Repeat this procedure as often as needed to reduce the frequency of the weeping 

of the P & T Valve. If the weeping persists after following this procedure, you may 

elect to install an expansion or accumulator tank in the cold water line to relieve 

the pressure caused by thermal expansion.

Suitable fittings are required to be installed in the pressure relief valve for piping 

water away. A hole for the discharge pipe must be drilled in the bottom of the 

control housing and the piping passed through the hole. The hole through which 

the piping passes must be sealed water tight.

The discharge pipe must not be reduced in size along its length. The length and 

number of bends should be kept to a minimum and should be supported in a 

manner to reduce the risk of crushing or blockage.

Please contact your local dealer for assistance.

DRAINING AND STORAGE INSTRUCTIONS

If unit is to be stored during the winter months, the heater must be drained to 

prevent damage in the case of freezing temperatures.

 1. 

Turn off electrical supply to the water heater.

 2. 

Turn off pressure pump on the water system.

 3. 

Open both hot and cold water taps.

 4. 

Open the drain on the water heater. (Remove anode rod)

 5. 

Follow RV manufacturer’s instructions for draining of the entire water 

system.

NOTE

: Be certain to refill water heater with water before using the appliance.
