Vent Termrnal
system during
Periodically inspect the vent for obstructions or presence of soot. Soot is
formed whenever combustion is incomplete. This is your visual warning
that the water heater is operating in an unsafe manner. lf soot is present,
immediately shut the water heater down and contact your dealer or a
qualified service person.
When considering add-on rooms, porch or patio, attention must be given
to the venting of your water heater. For your safety, do not terminate the
vent on your water heater inside add-on rooms, screen porch or onto
patios. Doing so will result in products of combustion being vented into
the rooms or occupied areas.
Never operate the heater if you smell gas. Do not assume that the smell
of gas in your RV is normal. Any time you detect the odor of gas, it is
to be considered life threatening and corrected immediately. Extinguish
any open flames including cigarettes and evacuate all persons from the
vehicle. Shut off gas supply at LP gas bottle. (See the Safety notice on
front cover of this manual.)
NOTE: Always open both the cold and hot water faucets when filling
vehicle water tank to allow air pockets to be forced out of the water
heater, When water flows from the faucets, close both faucets.

OPERATING INSTRUCTIONS
- Electric Elements -
Electric water heaters are
designed to operate with a
minimum amount of service
problems; however, proper
operation and care is
essential.
By far the most common
trouble with electric water
heaters results from
energizing the water heater
before it is fllled with water
Even brief operation of the
electric element without
water in the tank will burn-out
the electric heating element.
Before the electric element EcoswrcH &r-srAr
will operate, the switchl2ovELEcrRrcELEMENroNLY
Iocated behind the water
heater door in the lower left
corner of the control housing
must be in the "ON' position.
To energize the electric
element, locate the Switch,
Lamp and Plate assembly
(see Figure 8) inside the RV
and turn the switch marked
'ELECTRIC' to the "ON"
position. The water heater
temperature will be regulated
by the thermostat.
lf the unit is not properly derated, lack of sufflcient orygen for combustion
may produce improper burner operation. Pilot outage ffiused by burner lifloff
or sooting from a yellow burner may occur indicatrng the possibility of carbon
monoxide. You may also notice a lack of efficiency in heating the water because
of incomplete combustion of the burner at these higher altitudes.
Consult with the local gas company, your dealer, an RV service agency or
Suburban Manufacturing Company for proper derating of the unit. Change-out of
the burner/orifice (derating) should be done by the dealer or a qualified service
agency.
NOTE: lt is important that once the unit has returned to lower elevation (below
4,500 feet), this high altitude deration and pilot adjustments (if equipped) be
reversed for proper operation of the unit.
TO TURN OFF WATER HEATER
Turn switch to "OFF'positlon.
Turn off electrical power to the appliance.
Turn off gas supply.
lf vehicle is to be stored or heater is going to be turned off whjle subject to
freezing temperature, drain water heater. (See "Draining and Storage
lnstructions.")
MAINTENANCE
WARNING! lf the user of this appliance fails to maintain it in the condition
in which it was shipped from the factory or if the appliance is not
used solely for its intended purpose or if appliance is not maintaindd
in accordance with the instructions in this manual, then the risk of a
fire and/or the production of carbon monoxide exists which can cause
personal injury, property damage or loss of life.
WARNINGT For your safety, all repairs should be performed by your
dealer or a gualified service person.
A. Main Bumer Do not allow the burner to burn with a yellow flame, because
sooting will occur. (See Safety Warnings). lf the burner flame is yellow and
has an enatic pattern, shut unit down and contact a qualified service agency.
Do not continue operating unit with improper burner flame. (See Figure 1 1 for
correct and incorrect burner flame appearance.)
B. Periodically inspect irnit for soot. lf soot is present anywhere on watef heater,
immediately shut unit down and contact your dealer or a qualified service
person. Soot is a sign of incomplete combustion and must be corrected
before operating water heater. Areas to check would include:
1. Check for an obstruction in burner or the flue box.
2. Check the screen in the door to see that no foreign material has
accumulated to prevent flow of combustion and ventilating air.
3. Check to be sure there is no flame present at burner oriflce or burner
wheneyer main gas valve is closed. This can be checked by turning the
OFF/ON switch to the "OFF" position.
C. Frequent checks should be made of the grommet on the gas inlet to assure
tight seal. (See "Making Gas Connections").
D. Periodically check wiring and wire connection to be sure wiring is not
damagedlfrayed and that all terminals and connections are t;ght and in
compliance with codes (See "Making Wre Connections").
DRAINING AND STORAGE INSTRUCTIONS
lf RV is to be stored during winter months, the water heater must be drained to
prevent damage from freezing.
1. Turn off electrical power to water heater eiiher at the switch from the electrical
element or at breaker.
2. Shut off gas supply to water heater.
3. Turn off pressure pump on water system.
4. Open both hot and cold water faucets.

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.
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 waterfrom tank whenever RV is not being used. Avoid
any extended time of non use with water in tank.
Also, refer to section on winterizing.
WARNING! Do not replace the anode rod with any non-Suburban
accessory part, such as an "add-on" electric heating element. ltems such
as these are not approved to be installed in Suburban products. They
could create an unsafe condition and will also void all warranties,
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 ts similar to
rotten eggs and is often referred to as "sulphur water". lt is not harmful - only
unpleasant to smell. Sulphur water can be caused by a chemical action or by
bacteria. The solution to eliminate is chlorination of the water system. Add about
six (6) ounces of chlorinated common household liquid bleach to each 10 gallons
in the water tank. Then run the chlorinated water throughout 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 will need to take
care of the chlorine. Remove the chlorine by flushing the system with fresh water.
This may take several attempts. You may consider adding a filtering system that
removes chlorine and prevents sulphur water. lf the sulphur or rotten egg smell
continues, flush the system once again as described above and replace anode
rod as necessary.
PRESSURE RELIEF VALVE
The temperature and pressure relief valve is designed to open if the temperature
of the water within the heater reaches 21 ffi, or if the water pressure in the heater
reaches 1 50 pounds. Recreational vehicle water systems are closed systems and
during the water heating cycle the pressure build-up in the water system will reach
150 pounds. \Men 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.
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. V\hter
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.
WARNING! Do not remove or plug the 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 offwater heater.
2. Turn off cold water supply line.
3. Open a faucet 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 &TValve - it should snap closed.
6. Close faucet and turn on cold water supply; as the tank fllls, the air pocket
will develop.
Repeat this procedure as often as needed to reduce the frequency ofthe weeping
of the P & T Valve. lf the weeping persists after following this procedure, you may
elect to install an expansion or accumulator tank in the cold water line between
the tank and check valve to relieve the pressure caused by thermal expansion.
Contact your local dealer for assistance.
