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 from the electrical
element or a 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 rell water heater with water and remove all air from tank
and lines before re-lighting or before turning on electrical power.
ODOR FROM HOT WATER SYSTEM
Odor from the hot water system is not a service problem and many water
supplies contain sufcient amounts of sulphur to produce an odor. The odor is
similar to rotten eggs and is often referred to as “sulphur water”. It 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 ushing the system
with fresh water. This may take several attempts. You may consider adding a
ltering system that removes chlorine and prevents sulphur water. If the sulphur
or rotten egg smell continues, ush the system once again as described above
and replace anode rod as necessary.
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 SW10D, SW10DE SW12D, SW12DE, SW16D and SW16DE
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”.
WINTERIZING
If your water heater plumbing system is equipped with a bypass kit, use it to
close off the water heater, drain the water heater completely and leave the water
heater closed off (out of the system) in the bypass position particularly if you are
introducing antifreeze into the plumbing system. Antifreeze can be very corrosive
to the anode rod creating premature failure and heavy sediment in the tank. If the
plumbing system is not equipped with a bypass kit, and you intend to winterize
by adding antifreeze to the system, remove the anode rod (storing it for the
winter) and replace it with a 3/4” drain plug.
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING! If the user of this appliance fails to maintain it in the
condition in which is was shipped from the factory or if the appliance is
not used solely for its intended purpose or if appliance is not maintained
in accordance with the instruction in this manual, then the risk of a re
and/or the production of carbon monoxide exists which can cause
personal injury, property damage or loss of life.
OPERATING AND LIGHTING INSTRUCTIONS
WARNING! If you do not follow these instructions exactly, a re or
explosion may result causing property damage, personal injury or loss
of life.
WARNING: Before operating water heater, be sure tank is lled with
water. See “Safety Warnings”.
A. This appliance does not have a pilot. It is equipped with an ignition device
which automatically lights the burner. Do not try to light the burner by hand.
B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to
smell next to the oor because some gas is heavier than air and will settle on
the oor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch.
• Do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas
supplier’s instructions.
• If you cannot reach your gas supplier, call the re department.
C. This is an automatic gas valve, no adjustments are necessary. Do not attempt
to repair the gas valve. This may result in a re or explosion.
D. Do not use this appliance if any part has been under water. Immediately call
a qualied service technician to inspect the appliance and to replace any part of
the control system and any gas control which has been under water.
E. Before operating water heater, check the location of the vent to make sure it
will not be blocked by the opening of any door on the trailer. If it can be blocked,
do not operate the water heater with the door open.
OPERATING INSTRUCTIONS
1. STOP! Read the safety information provided.
2. Turn off all electric power to the appliance.
3. Turn “OFF” gas supply.
4. Wait ve minutes for gas to clear the area. If you smell gas then STOP!
Follow instructions in item B of the safety information. If you don’t smell gas, go
to next step.
5. Turn “ON” gas supply.
6. Turn on electrical power to the appliance.
7. Turn switch to “ON” position. If the burner does not light, the system will
automatically attempt two more tries for ignition before lock-out. NOTE: Each
ignition cycle will have a 15 second purge before spark cycle if system is a three
try system.
8. If lockout occurs before main burner lights, turn switch to “OFF”, wait ve
seconds and turn switch to “ON” position. This will restart the ignition cycle. The
rst start-up of the heater may require several ignition cycles before all air is
purged from the gas lines.
If the burner will not come on, the following items should be checked before
calling a service person.
1. Switch turned off.
2. Gas supply to heater is empty or turned off.
3. Reset button on ECO is tripped.
OPERATING INSTRUCTIONS
FOR UNITS WITH ELECTRIC ELEMENT
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 lled with water. Even brief operation of
the electric element without water in the tank will burn-out the electric heating
element.
To energize the electric heating element, turn the switch to “on”. The switch
is located behind the water heater door in the lower left corner of the control
housing. The water temperature will be regulated by the thermostat.
