Suburban SW3P User Manual

X. S AFETY WARNINGS
Should overheating occur, or the gas supply fall to shut off, shut off the
manual gas valve to the appliance before shutting off the electrical
supply.
Do not use this appliance If any part has been submerged underwater.
Immediately call a qualified service technician to Inspect the appliance
and to replace any part of the control system and any gas control that
has been submerged under water.
Do not alter the operation of your water heater nor change the
design/construction of your water heater. Accessories are being
marketed for RV products which we do not recommend. For your
safety, only factory authorized parts are to be used on your water
heater.
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. If 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 room or occupied areas.
Never operate the heater If you smell gas. Do not assume that the smell
of gas in you RV is normal. Any time you detect the odor of gas. It is to
be considered life threatening and corrected immediately. (See Safety
notice on front cover of this manual.)
WARNING! Make sure water heater is filled with water before power is
turned on. Even momentary operation of heater without water in it will
burn out the element.
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 heater faucets, close both faucets.
WARNING! Do not store or use combustible materials or liquids near
or adjacent to this heater. The appliance shall not be Installed In any
location where flammable liquids or vapors are likely to be present.
XI. A N O D E PROTECTION
The tank in this water heater is protected by a magnesium or aluminum anode 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).
XII. P R E SS U R E RELIEF VALVE
The temperature and pressure relief valve 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. 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. 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.
XIII. THERMOSTAT AND MANUAL RESET
MODELS: SW6D, SW6DE and SW6DM (See Figure 17)
The model water heaters listed above are equipped with a high temperature limit
as a cut-off device. Temperature above 180° F will cause manual reset button to
trip shutting down main burner
To activate burner, the water temperature must be below 100°F, push reset
button to re-activate burner.
XIV. THERMOSTAT AND MANUAL RESET
MODELS: SW6PE, SW6PER and SW6DE (See Figure 18)
The model water heaters listed above are equipped with a high temperature limit
as a cut-off' device. Temperature above 180° F will cause manual reset button to
trip shutting down the electric element.
To activate element, the water temperature must be below 100°F, push reset
button to re-activate the electric element.

XV. DRAINING AND STORAGE INSTRUCTIONS
If 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 either at the switch for 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.
5. Remove anode rod from tank;-
6 . Follow RV manufacturer's instructions for draining entire water system.
NOTE: Be certain to refill water heater with water and remove all air from tank
and liner before re-lighting or before turning on electrical power.
XVI. 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". Sulphur water 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 (6) ounces of chlorine (common household
liquid bleach) to each 10 gallons in the water tank. Then run the heavily
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. If you don't
have a water filtration system that removes chlorine, you will have a problem
getting rid of the chlorine taste. You might consider adding such a system
because it allows you to keep the water chlorinated and this prevents several
problems, including sulphur water. Chlorination also takes care of other types of
bacteria and viruses.
XVII. REMOVING WATER HEATER
1. Shut-off gas supply and disconnect gas supply line from water heater.
2. On all Electric Models, disconnect 120 V.A.C. supply at junction box mounted
on heater.
3. On all DSI Models, disconnect 12 V.D.C. power supply at junction box on
heater.
4. On Models SW6D and SW6DE disconnect all wires at module board.
5. Shut-off water supply. Drain water from tank following instructions under
"Draining and Storage".
6 . Disconnect hot and cold water lines from water heater.
7. Remove screws or nails securing control housing to framed opening.
8 . Slide heater out. To reinstall, follow instructions in manual under "Installation
Instructions".
